HT-670x Series Humidity Transmitters come in both wall or duct mount packages to meet a variety of sensing application needs. These attractively styled
controllers offer ease of installation and application flexibility. The transmitter generates a jumper-selectable output signal in either the 4 to 20mA or 0 to 10V range, corresponding to 0 to 100% Relative Humidity (RH). TrueRH transmitters can measure RH within either ±2% or ±3% accuracy. The 2% models include a National Institute of Standards and Technology (NIST) certificate of conformance. The patented All-Polymer™ humidity sensor construction improves resistance to chemical corrosion.
