Description

The combined air temperature and relative humidity sensors are specially designed for meteorological applications.

The sensors can be different depending on client needs (measuring range, accuracy, response times, operating environment...): METEO OMNIUM can tailor the type of probe to be installed depending on the situation.


Specific shelters used to protect the probe from solar radiation and severe weather can be different depending on the desired accuracy for measurements.
Accuracy related to the shelter, especially its variation depending on wind speed and solar irradiance, makes air temperature measurements problematic.
The quality of the shelter is essential to guarantee a renewal rate of the air inside the shelter and thus guarantee the most accurate measurement.

Meteorological characteristics

A single module performs the two measurements: air temperature and humidity.

The sensor should be located in the shelter 2 metres above the ground in an open area.
To maintain the accuracy of the sensor, it is necessary to subject it to an inspection once a year.
