Product Details


Humidity testing equipment is also called constant temperature and humidity test box, is a professional temperature and humidity aging test equipment,Widely used in battery, electronics, chemical, digital, LED, plastic, display, digital technology, instrumentation, medical and other industries.

Small high-low temperature wet heat test chamber is a necessary testing equipment in aviation, automobile, home appliances, scientific research and other fields. It is used for testing and determining electricians,Electronic and other products and materials for constant test temperature and humidity environment changes after the parameters and performance.


Structure characteristics of small high-low temperature wet heat test box:

1. The box body is processed and shaped by CNC machine tools. The shape is beautiful, elegant, novel and adopts non-reaction handle, which is easy to operate.

2. The tank is made of imported advanced stainless steel (SUS304) mirror plate or 304B argon arc welding, and the tank is made of A3 steel plate.

3. Microcomputer temperature and humidity controller is adopted to control temperature and humidity accurately and reliably.(Japanese OYO instrument)

4. It is equipped with a large observation window and a light to keep the box bright. Double glass is used to clearly observe the status of the box at any time.

5. Unique independent temperature limiting alarm system, which will automatically interrupt when the temperature exceeds the limit to ensure the safe operation of the experiment without accidents.

6. Recorder is optional. The printer can print the setting parameters and scan the temperature and humidity change curve, 4 ~ 20mA standard signal.

7. The left side of the box is equipped with a test hole with a diameter of 50mm.
