- The separation of the humidifier circuit from the electric circuit improves safety and protects the circuit against leakage from the water supply line.
- Available in Chinese and English LCD touch screen, easy operation and programming.
- The programmable temperature humidity test chamber is able to display the relative date and information of the whole operating system in running mode with graphic display. Precautions, maintenance, and troubleshooting appear on the screen instantly.
- The Sirocco fan motor provides greater cyclic airflow to avoid dead corners in the chamber, obtaining a uniform distribution of temperature and humidity.
- The systems of heating up, cooling down, dehumidifying, and humidifying can be operated independently to reduce the cost of testing, extend the operating life of the machine, and decrease the failure rate.
- Water supply adopts an automatic watering system, circulating water supply together with a water filter.
