The device is based on a microcontroller and uses digital sensors. Real time measurement and control of temperature and humidity in one channel, and display them in digital form. According to the actual needs of temperature and humidity measurement and control, the upper and lower limits and hysteresis of temperature and humidity can be set separately to achieve automatic adjustment of temperature and humidity in the tested environment. The device has high precision and stable operation. Suitable for various occasions that require temperature and humidity detection and control. Especially for the anti condensation circuit protection of various high and low voltage switchgear box type substations in the power system.

Data is being organized ..

1. Measurement range: Temperature: -40 ℃ to+80 ℃ Humidity: 0% RH to 98% RH

2. Measurement accuracy and resolution Temperature: accuracy ± 0.5 ℃ resolution 0.1 ℃ Humidity: accuracy ± 3% RH resolution 1RH%

3. Parameter setting range

Temperature upper limit setting range: 17 ℃ to 50 ℃. If the ambient temperature is higher than this value, start the fan. Temperature hysteresis setting range: 1 ℃ to 30 ℃. The temperature limit minus the temperature hysteresis is the temperature value at which the fan stops. Humidity upper limit setting range: 60% RH to 90% RH. If the ambient humidity is higher than this value, start the heating and fan. Humidity hysteresis setting range: 1% RH to 50% RH, the upper humidity limit minus the humidity hysteresis value, which is the humidity value for stopping heating and fans.

4. Heating and fan contacts: passive contacts, capacity 5A/250V AC

5. Applicable power supply:

AC/DC220V or AC/DC110V

6. Device power consumption:<5w

8. Installation size: 66mm × 66mm

9. Usage environment: Temperature: -40 ℃ to+60 ℃

Relative humidity: ≤ 95% RH. There should be no conductive dust or corrosive gases such as mold that can cause insulation damage in the surrounding area.
