The duct humidity and temperature sensor DHT measures the humidity and temperature of air.

The DHT converts the measurements of humidity and temperature into standard signals of 0-10 Vdc or 4-20 mA, temperature passive sensor PT1000, PT100, NTC, NI1000 also available as direct temperature output.

The DHT can be ordered with or without display.

DIP switch on pcb to select relative humidity, absolute humidity or dew point measurement.

Built-in display for room humidity and temperature showing actual humidity and actual temperature.

Probe length is 220 mm.

Mounting flange is included.

New LCD Display 2019

The LCD display simultainously shows the current values of each parameter on a clear, easy to read colour screen.
