Constant Stability Test Chamber Climate Environmental Test Chamber
Laboratory Programmable Temperature Humidity Test Chamber of
commerceProduct descriptionConstant temperature and humidity test chamber is also called
constant temperature humidity test machine, temperature and
humidity chamber, programmable damp and heat alternating test box,
constant temperature machine or constant temperature and humidity
box. It is used to test the performance of materials in various
environments. This kind of material has heat resistance, cold resistance, dry
resistance and humidity resistance. It is suitable for testing the quality of products such as
electronics, electrical appliances, mobile phones, communications,
meters, vehicles, plastic products, metals, food, chemicals,
building materials, medical care, aerospace, etc.

7,GB/T 10589-2008
8,GB/T2423.3-2008(IEC68-2-3)Specification:
1. The separation of humidifier circuit from electric circuit
improves safety and protects the circuit against the leakage of
water supply line.
2. Available in Chinese and English LCD touch screen, easy
operation and program.
3. Programmable temperature humidity test chamber is able to
display the relative date and information of the whole operating
system in running mode, graphic display. Precautions, maintenance
and troubleshooting appear on the screen instantly.
4. The Sirocco fan motor provides greater cyclic airflow to avoid
dead corner in the chamber so as to obtain an uniform distribution
of temperature and humidity.
5. The system of heating up, heating down, dehumidifying, and
humidifying can be operated independently so as to reduce the cost
of testing, extend the operating life of the machine and decrease
the failure rate.
6. Water Supply adopts automatic watering System, Circulating water
supply together with water filter.Technical parametersModel | BT-280 | BT-2150 | BT-2225 | BT-2408 | BT-2800 |
