The HygroMet4 is suitable for use wherever high humidity prevails for short or long periods. In such environments condensation could occur on conventional probes, thereby delivering incorrect values. This is particularly the case in meteorology, in cheese cellars, tunnels and caves.
Heating Function
The HygroMet4 is equipped with an automatic sensor heater. It heats the sensor above ambient temperature by 0.1…10 °C depending on the settings. Heating of the sensor prevents the formation of condensation.
The following heating cycles can be selected and are programmable by the user:
- Permanent heating
The sensor is constantly heated.
- Interval
The heater can be switched on hourly, daily, weekly or monthly at a defined point in time. The heating duration can also be defined as needed.
- Depending on current measured values
The sensor heater can be programmed to switch on when a specified humidity or temperature value is reached or exceeded.
Sensor cleaning
The programmable cleaning function heats the sensor to 150 °C. The cleaning function can be switched on daily, weekly or monthly at a definable point in time. The duration of the heating function can also be defined.
