  • Humidity: 0-95%RH (non-condensing)
  • Humidity Accuracy: +/-1% from 15°C to 40°C (0 to 90%);
  • One 4-20mA Loop Power Output 
  • Two Line LCD
  • Nist Calibration Certificate Included        

 The HR200 transmitter is designed to operate in extremely high humidity and temperature environments and performs superbly in chemical resistance application. The humidity sensor is capable of measuring 0 % RH to 100 % RH and operates within a temperature range of -40 °C to +190 °C.

additional advantages include:

    High chemical resistance
    Very low drift
    Wide temperature range
    High humidity stability
    Condensation resistant
    Suitable for extreme environments
    Fast recovery time

The HR200 humidity transmitter offers relative humidity with NIST traceable calibration. It includes a sensor probe which connects to an electronics unit. The probe features an all steel construction coupled with a cable that allows temperatures up to 200°C.  For pressure applications the probe is capable of handling 750PSI.  The electronics unit has a two line LCD display and both a digital RS232 output and 4/20mA output.

 The 4-20mA output is scaled to equal 0-100 percent relative humidity.

The HR200 is ideal for environmental chambers, clean rooms and high temperature applications.

It works with inert gases such as Argon, Helium, Nitrogen and other noble gases.   Air, Oxygen, Hydrogen, CO2, CO and ammonia (NH3) are additional gases the sensor performs well in. If you have any questions about your gas application , please contact IOThrifty.
