In modern industrial manufacturing, industrial precision ovens are key "temperature artisans". They are widely used in electronics, aerospace, automotive, medical and other fields, providing stable performance and reliable quality for products. Gaining an in-depth understanding of their principles not only clarifies the scientific logic of industrial production, but also helps practitioners use equipment efficiently to improve benefits.
(I) Heating System: The Source of Heat
The heating system is the "heat source core" of the oven. The thermostat controls the thyristor through signals to adjust the heater power and regulate heat output: full power is supplied when the temperature is much lower than the set value, power gradually decreases when approaching the set value, and output stops when the set value is reached. This is energy-efficient and achieves high temperature control precision.
(II) Air Circulation System: The Messenger of Heat Transfer
Composed of a blower motor, extended shaft and multi-wing fan blades, the air circulation system is critical for heat transfer. The motor drives the wind wheel to rotate and form air flow, which is evenly delivered to all areas of the oven through optimized air ducts, avoiding dead corners and temperature differences. Hot air fully contacts materials during circulation to achieve rapid and uniform heating, which is essential for high-precision processes such as electronic chips and optical lenses.
(III) Electrical Control System: The Core of Precise Operation
The electrical control system is the core control unit of the oven. The Q8 series electrical control system adopts full-touch operation with a control precision of 0.01 level and supports multiple sensor adaptations. It has 100 built-in processes (50 steps per group), including EVT, cold output and transmission output functions. The DO channel features safe isolation and arc suppression design, enabling convenient, accurate and reliable operation that adapts to diverse control scenarios.
Future Outlook: Technological Innovation Leads Development
In the future, industrial precision ovens will focus on three major innovation directions: intelligence, energy conservation and environmental protection, and special process adaptation, continuously innovating to shape a new industrial future.
As core industrial equipment for precise temperature control, drying and curing, precision ovens’ operational stability directly impacts product quality and production efficiency. Scientific maintenance extends service life and ensures process parameter accuracy. Below are key methods divided into daily basic maintenance and regular in-depth maintenance.

3. Standardized Operation: Reduce Human-induced Wear
Avoid overloading workpieces and ensure proper spacing for hot air circulation to prevent local overheating. Follow the manual for temperature rise/drop—no sudden startup/shutdown or drastic adjustments to avoid furnace cracking. Turn off main power only when temperature drops below 50℃ to extend heating element life.
II. Regular In-depth Maintenance: Enhance Core Performance
Recommended monthly or quarterly, regular maintenance focuses on core components and requires professional technicians.
1. Heating & Circulation System Overhaul: Ensure Efficiency
Inspect heating tubes for oxide layers, scale or abnormal resistance (replace if needed), and clean/fasten junction box terminals with insulating grease. Disassemble fan impellers to remove dust and oil, lubricate bearings, replace damaged seals and adjust air duct baffles for uniform hot air circulation.
2. Temperature Control Calibration: Improve Accuracy
Calibrate temperature sensors with a standard thermometer—adjust parameters or replace sensors if deviation is excessive. Inspect signal transmission lines for interference or poor contact. Verify multi-stage heating curve accuracy for programmable ovens.
3. Furnace Structure Maintenance: Extend Service Life

In industrial manufacturing's "quality defense line", walk-in environmental test chambers are low-key yet critical. As "environmental simulation masters", they replicate extreme conditions from polar cold to tropical heat, testing large equipment and batch products. Their hidden technical strengths merit in-depth exploration.
I. Spacious Interior for Flexible Adaptation to Diverse Testing Needs
The "walk-in" design is a core breakthrough. With several to dozens of cubic meters of space, it accommodates large products (automotive parts, electronic devices) and enables batch testing of small/medium items. New energy vehicle battery packs and rail transit systems can be tested integrally without disassembly. Flexible racks and zoning fit various sample shapes, solving traditional equipment's "unfit and unstable" issues.
II. Precise Temperature Control for Highly Simulating Diverse Extreme Environments
Precise temperature control is its core advantage, with a temperature range of -70℃ to 250℃ and humidity of 20%RH to 98%RH, replicating high-altitude, desert and coastal environments. Using PID algorithms and multi-point sensing, temperature/humidity fluctuations are controlled within ±0.5℃ and ±2%RH, ensuring reliable data. It simulates high-altitude conditions for aerospace and verifies consumer electronics' performance in extremes to support product iteration.
III. Energy Conservation and Environmental Protection for Long-term Operating Cost Optimization
To address high energy consumption, it adopts variable frequency compressors and low-power heating modules for intelligent power adjustment. Double-layer vacuum insulation reduces heat exchange, and high-end models feature waste heat recovery. Energy consumption is cut by over 30% vs. traditional equipment, saving tens of thousands in annual electricity costs. Stable operation lowers maintenance needs and extends service life, reducing long-term costs.

In addition, you can choose a suitable model based on your needs. Lab Companion provides customized services if existing specifications are insufficient .
V. Conclusion: The "Core Driving Force" for Industrial Quality Upgrading
With large space, precise control, energy efficiency and durability, these chambers are industrial testing's "quality stewards". Critical for improving product reliability in manufacturing transformation, they will upgrade to more precise and intelligent versions to empower industrial high-quality development.
As core equipment in industrial production and scientific research that accurately simulates complex environmental conditions such as high and low temperatures, and humidity, the safe and stable operation of test chambers not only directly affects the test process, but is also closely related to the characteristics of test samples. To maximize the protection of the performance of the equipment's core components, avoid safety risks during operation, and ensure the accuracy and reliability of the final test data, all models of test chambers have established clear and strict restriction standards for sample selection. Testing and storage of the following models of samples are strictly prohibited.
The specific prohibited scope includes:
• Flammable substances such as gasoline and ethanol, explosive substances such as gunpowder and acetylene, and volatile substances such as methanol and ether;
• Corrosive substances such as strong acids, strong alkalis and various corrosive solvents that may damage the equipment cavity;
• Biological samples such as microorganisms, cell tissues and living organisms that may cause pollution or safety hazards;
• Samples that are strong electromagnetic emission sources such as high-frequency emission modules, which may interfere with the equipment's control system;
• Radioactive substances with radiation hazards such as uranium and cobalt;
• Highly toxic substances that pose serious hazards to humans and the environment, such as cyanides and highly toxic pesticides;
• All models of samples that may generate flammable, explosive, volatile, highly toxic, corrosive, or radioactive substances due to changes in temperature and humidity during the testing or storage process.
Before starting the test chamber, operators must confirm the specific properties of the samples through professional testing methods or authoritative materials, and strictly abide by the above restriction requirements. If there is any doubt in judging the applicability of the samples, they should consult the technical personnel of the equipment manufacturer or experts in related fields immediately, and must not operate blindly based on experience. This is to avoid equipment cavity damage, control system failure, safety accidents, or serious deviations in test data caused by illegal use.
1. Preparation for Load-bearing and Dimensional Adaptation
• The load-bearing capacity of the site floor shall strictly meet the core requirement of ≥500kg/m², which is a key prerequisite for ensuring the long-term stable operation of the equipment and avoiding equipment deformation or safety hazards caused by insufficient load-bearing capacity.
• It is necessary to accurately confirm the external dimensions of the test chamber specified in the technical specification in advance. Combined with the on-site actual survey of the transportation and installation path, ensure that the equipment can smoothly pass through all key passage nodes such as elevators, laboratory doors and corridors, so as to avoid delay in delivery and installation due to inconsistent dimensions.
2. Preparation for Installation Site Conditions
• The floor of the installation site shall be flat without protrusions and depressions, and the ventilation conditions shall meet the basic standards for equipment operation. At the same time, there shall be no flammable, explosive, corrosive gases or dust in the environment, as such substances will seriously affect the service life of equipment components and the accuracy of test data.
• Strong electromagnetic radiation sources such as high-voltage lines and large motors should be actively avoided near the equipment installation location, as strong electromagnetic interference may cause disorder of the equipment control system, thereby affecting the temperature and humidity control accuracy of the test chamber.
• A floor drain that meets the drainage standards must be provided within 2 meters of the equipment's refrigeration unit. This requirement is to timely discharge the condensed water generated during the operation of the refrigeration system, so as to avoid water accumulation soaking the equipment or polluting the site environment.
• Sufficient maintenance and operation space shall be reserved around the equipment in accordance with specifications. The specific requirements strictly follow the following standards: Area A ≥80cm, Area B ≥60cm, Area C ≥110cm, Area D ≥110cm. Sufficient space is a necessary guarantee for later equipment maintenance, calibration and component replacement.

Through accurate monitoring, rapid response and effective intervention, each protection device not only ensures the long-term stable operation of the equipment and extends its service life, but also safeguards the safety of test samples and personnel operation. It serves as the core support for reliable test processes and accurate results, building a solid safety barrier for product quality verification.
In environmental reliability testing, high-low temperature humidity test chambers and constant temperature and humidity test chambers are easily confused due to similar names, but they differ significantly in testing capabilities, applications and technical characteristics. Accurate distinction and selection are key to ensuring valid test data. This blog will analyze the core differences and provide selection suggestions.
I. Core Definition: Essential Distinction of Functional Boundaries
The core difference between the two starts with functional positioning, which directly determines the applicable scenarios.
The core of the constant temperature and humidity test chamber is "maintaining stability". It can accurately control and maintain the set temperature and humidity for a long time, and is used to simulate the long-term performance of products in specific environments, such as electronic component stability testing and textile temperature-humidity sensitivity testing. Its core requirement is "steady-state environmental performance verification".
The high-low temperature humidity test chamber focuses on "dynamic simulation". In addition to precise temperature and humidity control, it has a wide-range fluctuation capability, which can simulate environments such as high-low temperature cycles and alternating humidity and heat, such as extreme temperature differences during product transportation and diurnal temperature-humidity changes of outdoor equipment. Its core requirement is "dynamic environmental reliability verification".
II. Key Differences: Multi-dimensional Analysis from Technology to Application
1. Temperature and Humidity Range and Fluctuation Capacity
The constant temperature and humidity chamber has a mild temperature and humidity range (temperature 0℃-100℃, humidity 30%-95%RH) and high control precision (temperature fluctuation ±0.5℃, humidity ±2%RH), but no extreme temperature-humidity impact capability.
The high-low temperature humidity chamber has a wider temperature and humidity coverage (temperature -70℃~200℃, humidity 10%-98%RH) and rapid change capability (heating rate 3℃/min-15℃/min, cooling rate 1℃/min-10℃/min), which can realize rapid cycle switching between "high temperature and high humidity - low temperature and low humidity"—a feature unavailable in the former.
2. Differences in Core Technical Architecture
The constant temperature and humidity chamber adopts single-stage compression refrigeration, conventional resistance heating, and steam or ultrasonic humidification. Its system design focuses on "energy saving and stability", with simple structure and low operating cost.
To meet extreme needs, the high-low temperature humidity chamber uses cascade refrigeration, rapid-heating tubes, and its humidity system includes a fast-response dehumidification module, with a thicker insulation layer on the chamber wall. Its technical complexity and manufacturing cost are much higher than the former.
3. Applicable Scenarios and Testing Purposes
The constant temperature and humidity chamber is used for steady-state environmental adaptability testing, such as electronic component aging and pharmaceutical storage simulation, to verify the performance consistency and durability of products in a fixed environment.
The high-low temperature humidity chamber focuses on dynamic reliability testing, such as high-low temperature cycling of auto parts and extreme environment simulation of aerospace products, to expose product defects (material aging, structural deformation, etc.) under drastic environmental changes.
In summary, the constant temperature and humidity chamber guards the steady-state environment, while the high-low temperature humidity chamber challenges the dynamic environment. There is no absolute advantage or disadvantage between the two. Only by matching needs, clarifying scenarios and budgets can the test truly guarantee product quality.
Environmental test chambers simulate complex conditions such as high/low temperatures and humidity, widely serving industries including electronics, automotive, aerospace, materials, and medical devices.
