The 80L small high and low temperature test chamber has the advantages of small size, low power, and low power consumption. The only drawback is that large test samples cannot be placed, and they are only used for small or small industrial products. At present, Guangzhou Jingxiu Thermal Equipment Co., Ltd. produces the smallest high and low temperature test box with a volume of 80L; its inner box size is W400mm * D400mm * H500mm; The temperature range can be selected from -40 ℃ to 150 ℃; Humidity range from 25% RH to 98% RH.

1. Compact design, low noise, lightweight and compact, beautiful appearance, small body with large content, space saving appearance, suitable for office use.

2. The inner lining material of the box is made of imported high-quality stainless steel (SUS304), which has good low-temperature strength, corrosion resistance, heat resistance, and mechanical properties; Good hot workability such as stamping and bending, no heat treatment hardening phenomenon (non-magnetic, operating temperature -196 ℃~800 ℃), and the outer box is made of high-quality steel plate spray painted paint.

3. Adopting a microcomputer temperature and humidity controller, with a touch screen operation mode, the Chinese and English screens can be switched, completely automatically controlled and locked by the microcomputer, ensuring precise and reliable temperature and humidity control.

4. The large observation window adopts double-layer glass and is equipped with lighting, making it convenient to observe the test conditions inside the box clearly at any time.

5. 9 sets of PID control parameter settings, with PID value automatic calculation function, maximum program capacity of 120 sets, 999 cycle settings.

6. Equipped with an independent temperature limit alarm system, it will automatically interrupt when the temperature limit is exceeded, provide water shortage warning alarm, prevent dry burning alarm, and ensure safe operation of the test process.
