Description

The OHT is an outdoor humidity and temperature transmitter measures the humidity and temperature of air.

The outdoor humidity and temperature transmitter OHT converts the measurements humidity and temperature into standard signals of 0-10 Vdc or 4-20 mA.

Passive temperature sensor PT1000, PT100, NTC 10K, NTC 20K, NTC 1.8K, NI1000 etc as option

The OHT outdoor humidity and temperature transmitter can be supplied with or without LCD display.

The built-in LCD display on outdoor humidity and temperature transmitter OHT show actual humidity and actual temperature.
