HD2101.1 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, and the comfort indices.

The probes are fitted with an automatic detection module, with the factory calibration settings already being memorized inside.
HD2101.1 model are fitted with an RS232C serial port and can transfer the acquired measurements in real time to a PC or to a portable printer.

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.


The instruments have IP67 protection degree.
