DUCT HUMIDITY TRANSMITTER : GDH-110
"GDH" Duct Humidity Transmitter is intended for an Electronic Humidity Transmitter to measures the Duct Relative Humidity (RH) and convents the measurement into and electric signal.
This unit can be used with all system equipments that can receive output signals 0 - 10VDC of the detector.
● Electronic sensing circuit varies signal into 4 - 20mA DC (within 0 ~ 100% relative humidity)
● Sensing Accuracy is ±3% within usage range of 20 ~ 90%Rh.
