Delta - Model HD 2101.1 - HD 2101.2 -Portable Humidity Thermometer

The 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 air contact probes. The sensor can be a Pt100, Pt1000 or Ni1000. When the combined humidity/temperature 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 automatic detection module, with the factory calibration settings already. being memorized inside.
