Order # HTM-D-420, Economy 3% Duct Humidity Transmitter

Base Price $250.00 ( Quantity Discount Available )


  • Temperature compensated
  • 2-Wire, 4...20mA
  • Economical pricing
  • 3% accuracy
  • Measures 10 to 90% rH


  • Our temperature compensated humidity transmitter has been designed to meet the demands of energy management, environmental and process industries. The polymer based humidity sensor is one of the most stable sensors available. The 2 wire, 4-20 mA design provides ease of installation, lowering the cost of field wiring.
    The high accuracy over the wide range of 10-90% rH allows precise measurement of the humidity over the operating range of 0 to +60ºC. Even condensation on the sensor will not harm it.
    Each transmitter is calibrated in our computer operated atmospheric simulation chamber against our traceable Standard, a Condensation Dew Point Hygrometer.
