HD 2301.0


  • Portable temperature and humidity indicator
  • Suitable for both laboratory and field work

The HD2301.0 is a portable instrument with a large LCD display. It measures 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 vapor pressure.
The instrument has IP67 protection degree.

Measurement range 0…100%RH
Resolution 0.1%RH
Accuracy ±0.1%RH
Drift after 1 year 0.1%RH/year
