Top Suppliers Temperature And Humidity Sensor Rs485 – High Temperature and Humidity Transmitter up to 200 °C (392 °F) Integrated ±2%RH Humidity and Temperature Sensor for Industrial Process Monitoring and Control – HENGKO

The HT400 relative humidity meter is optimized for the best reliability in industrial applications from -40 °C (-40 °F) up to 200 °C (92 °F).In addition to highly accurate measurement of the relative humidity (RH) and temperature (T), the device calculates all other humidity-related parameters.

This temperature and humidity transmitter is specialized in strict industrial applications with HENGKO RHT series humidity measuring element. It has the advantage of accurately measuring, adapts to a wide temperature range, excellent chemical pollution resistance, steady working, and long service time, etc. 2-pin temperature and humidity 4-20mA current signal output.

Max temperature resistance: 200℃
 
The chip of the HT400 series temperature and humidity meter has excellent temperature resistance and can work under 200 ℃ for a long time. The special handling of the humidity sensor surface can make sensor keeping working in the chemical contamination. HT400 temperature humidity transmitter is the best choice in the high-temperature harsh environment.

Which HT400 humidity temperature transmitter is right for you?

> HT400-F

> HT400-Y

Note: The high temperature humidity sensor transmitter will cost about 1 minute to update its working status to ensure stable value measurement.

When Should Select High Temp? Temperature and Humidity Sensor

Common type temperature and humidity sensors usually have a max temperature of 80 Deg.C.(this is our product standard), and when the temperature is over 80℃. for long-term,e.g. 90℃ or over 100℃ or higher temperature. Under such conditions, it is better to select high temp. temperature humidity transmitter.
