Thermohygrometer
The station records continuously measurements of the seven meteorological standard parameters: air temperature, relative humidity, wind speed and direction, atmospheric pressure, global solar radiation and total precipitation. A thermohygrometer DMA572 LSi-Lastem(Italy) measures :
-air temperature (°C);
- relative humidity(%).

The DMA572 Thermohygrometer by Lsi-Lastem was installed in 2006 on Rwenzori Mountain. It is a probe for measuring air temperature and relative humidity with replaceable sensitive element for simplify calibration and maintenance. LSI-Lastem supplies a precise and reliable set of probes, suitable for a continuous measurement in severe environments, in presence of deep thermal and hygrometric ranges with high sun radiant heat. An important feature of this set of sensor is that the thermohygrometric sensitive element is easily replaceable, in order to have a simple and rapid ordinary maintenance and avoiding calibration. The Thermohygrometer has supported a considerable improvement, owing to a deep technical and styling development process: a fan ensures a continuous air change around the sensor in order to eliminate temperature fault caused by radiant heat.
