HD2,w/o LCD,Analog,2%RH,Temp Transmitter
HD2 Series Analog Humidity Sensors are duct-mounted devices that measure both humidity and temperature with solid-state sensors. They ensure accurate readings, improve energy efficiency, and help maintain proper building conditions. Each unit provides analog outputs (4-20mA, 0-5 VDC, or 0-10 VDC) and features a field-replaceable humidity sensor.
