Cooling Chamber/High Low Temperature Test Chamber/Temperature and Humidity Test Chamebr

Product Description:
Constant stability temperature humidity testing Machine is designed for testing the capability of heat-endurance, cold-endurance, dryness-endurance, and humidity-endurance, suitable for quality control of the industries of electron, electrical equipment, vehicle, metal, foodstuffs, chemistry, building materials, luggage, adhesion tape, printing, packaging, etc.

This temperature humidity test chamber can simulate high temperature and humidity, high temperature and low humidity, low temperature and high humidity, high temperature and low temperature environment conditions, assorted easy operation and study, high accuracy, programmable controller and fixed point system.
Cooling Chamber/High Low Temperature Test Chamber/Temperature and Humidity Test Chamebr
The temperature humidity test machine adopts Chinese and English touch screens, multiple sets of PID control functions, and RS-232C / 485C connected to the computer interface control. It can simulate different environmental conditions such as high temperature, high humidity, low temperature, high humidity, low temperature, low humidity, high temperature, and low temperature. It is also equipped with a highly accurate programming control and fixed-point control system that is easy to operate and learn. It is being identified and translated online.

Test accuracy:
2,GB/T 2423.2-2008
6,GBT 2424.5-2006

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.
