Features

1.Mainly applied as internal controller of temperature and humidity for high voltage switchgear, terminal box, ring network cabinet, box to change devices.

2.Effectively avoid equipment failure caused by low, high temperature and creepage, flashover problem caused by damp, condensation.

3.Display the temperature, humidity values by nixie tube.

4.Designed with heater, sensor fault indicator, transmitting function.

5.With RS485 communication interface for remote monitoring, the operator can set the system parameters by key programming.

6. Integrate measurement, display, control and communication function.

7. Fit for standard GB/T15309-1994.
