Thermohygrometer HD2101_1_2 (DELTA OHM)

Thermohygrometer-HD2101_1_2The HD2101.1 and HD2101.2 are portable instruments with a large LCD display. They measure relative humidity and temperature using a Pt100 sensor or thermocouple humidity/temperature combined probe. Temperature only is measured by immersion, penetration or contact probes. The sensor can be a Pt100 or Pt1000. When the humidity/temperature combined probe is connected,

 

the instrument calculates and displays the absolute humidity, the dew point, the partial vapour pressure, and the comfort indices. The probes are fitted with an automatic detection module, with the factory calibration data already stored inside.
