Small Size Temperature Humidity Test Chamber High Performance
Usage :
This equipment can simulate different environment condition. It's appropriate for testing material performance, such as resist heat, LED,resist dry,resist humidity and resist cold. That can define performance of material.
Charater :
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.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.
