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 vapour pressure. The probes are fitted with an automatic detection module, with the factory calibration data already stored inside.
The Max, Min and Avg function calculate the maximum, minimum or average values.
The instruments have IP67 protection degree.
