HD2301.0 measures humidity with combined probes:
- relative humidity and temperature with Pt100 or thermocouple.
- only temperature with immersion, penetration or contact.
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 settings already being memorized inside.
The functions of the thermohygrometer are:
• Max, Min, Avg function calculates the maximum, minimum and average values;
• relative measure REL;
• HOLD function;
• automatic shutdown which can be disabled.
