For standard environmental test chambers from our temperature chamber China product line, we can achieve a temperature range of -70℃ to 150℃ and a humidity range of 10% to 98% RH. As leading temperature chamber manufacturers, we ensure that every temperature chamber for sale meets these rigorous performance specifications.
Both the temperature and humidity test chamber and temperature and humidity cabinet cover an extremely wide range of testing conditions. The rapid temperature change series can achieve a heating and cooling rate of 5℃ to 25℃ per minute, demonstrating why we are preferred temperature chamber manufacturers for demanding applications. Every temperature chamber for sale from our temperature chamber china production line undergoes thorough quality testing before shipment.
Moreover, linear or non-linear temperature control can be optionally configured according to specific requirements. Customization of the temperature and humidity test chamber and temperature and humidity cabinet is also available to meet customers' specific needs.

The outer box is small in size, and the placement and movement of the equipment are not restricted by the site, which meets the requirements of testing in R&D units, office buildings, and production lines.
The equipment uses an original imported fully enclosed compressor with low vibration and low noise.
A complete safety system protects the normal operation of products and equipment.
The equipment introduces the concept of energy saving and environmental protection, and adopts a new low-temperature temperature control method in the temperature control process (this has been applied for a registered patent), which greatly reduces the energy consumption of the equipment.

Temperature Control System
Heating: The temperature inside the chamber is rapidly increased via electric heaters (such as resistance wires). A temperature sensor (e.g., PT100 platinum resistor) monitors the temperature in real-time and feeds the data back to a controller (such as a PID controller) to adjust the heating power. This precision is standard in every humidity chamber for sale from our lineup.
Refrigeration: Mechanical compression refrigeration cycles are mostly adopted, consisting of a compressor, condenser, expansion valve, and evaporator. The refrigerant absorbs heat in the evaporator to lower the temperature inside the chamber. As experienced humidity chamber manufacturers, we optimize these cycles for efficiency and reliability.
Air Circulation: A built-in fan forces air flow to ensure uniform temperature inside the chamber and avoid local temperature differences. Leading humidity chamber suppliers recognize this as essential for accurate test results.
Humidity Control System
Humidification
Steam humidification: Water is heated electrically to generate steam, which is directly injected into the chamber (fast but high in energy consumption). A self-developed humidification bucket is used by top humidity chamber manufacturers to balance performance and efficiency.
A temperature humidity chamber does not provide the same humidity capability at every temperature. Refrigeration capacity, air temperature, water-vapor content, condensation protection, and the system’s dew-point limit define the usable humidity envelope. Buyers should therefore compare the operating chart rather than reading only the headline range. Within the WJLANG temperature chamber China product range, standard models can cover wide temperature and humidity conditions depending on configuration, but the required profile, specimen load, and transition rate should be checked before selection. A temperature and humidity test chamber should also be evaluated for stability, uniformity, water quality requirements, sensor accuracy, data logging, and long-duration operation.
A standard temperature chamber is designed for stable high- and low-temperature exposure and moderate programmed cycles. A rapid-rate chamber adds greater heating and cooling capacity to achieve faster linear or non-linear transitions under defined loads. The faster option is appropriate for accelerated reliability screening, electronics qualification, and programs where ramp rate is part of the test requirement. Buyers should compare loaded ramp rate, overshoot, recovery, compressor configuration, noise, energy use, and specimen heat generation. When the profile requires repeated fast transitions, a thermal cycle chamber should be specified using the real sample mass and operating heat load, not empty-chamber performance alone.
For a temperature chamber China model, the nominal chamber volume does not determine test capacity by itself. Large fixtures, closely packed specimens, powered electronics, and obstructed airflow can reduce uniformity and slow temperature recovery. A temp humidity chamber should be selected after calculating usable volume, sample spacing, thermal mass, active heat load, cable routing, and sensor placement. Smaller components may be tested efficiently in a benchtop environmental chamber, while larger or higher-load assemblies require additional refrigeration and airflow capacity. WJLANG recommends defining acceptance points under representative load, including stability, deviation, uniformity, ramp rate, and recovery, so published performance can be translated into reliable test results.
