Equipment Introduction:
Programmable Constant Temperature Humidity Test Chamber 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.
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.
