Dwyer Instruments HHT-IT-LCD | Intrinsically safe humidity/temperature transmitter with LCD display

Name: Dwyer Instruments HHT-IT-LCD | Intrinsically safe humidity/temperature transmitter with LCD display
Brand: Dwyer
SKU: HHT-IT-LCD
Availability: OutOfStock

Part Number : HHT-IT-LCD

A hazardous area humidity/temperature transmitter, the Series HHT, Model HHT-IT-LCD, measures temperatures and humidity accurately even in the most hostile conditions. For humidity only, the explosion-proof type has an output of 4 to 20 mA. The temperature and humidity outputs on the intrinsically safe version range from 4 to 20 mA, and in order to comply with hazardous area regulations, an intrinsically safe barrier is needed.
