South Col Thermohygrometer

In 2008 expedition, at South Col was installed the DMA572 termohygrometer, that was replaced during the 2011 expedition with two DMA672 termohygrometers and one DMA033 thermometer. All these sensors are manufactered by LSI-Lastem (Italy).

DMA 672 thermohygrometer is an instrument for measuring temperature and relative humidity and suitable for a continuous measurement in severe environments; in presence of deep thermal and hygrometric ranges with high sun radiant heat. An importatnt 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 continuos air change around the sensor in order to eliminate temperature fault caused by radiant heat.
