Close to years Since 1925 Environmental Monitoring Solutions sensor of AIRCombined TEMPERATURE AIR TEMPERATURE AND RELATIVE AND RELATIVE HUMIDITY Combined sensor HUMIDITY t026t026 TTEPRH SMATRH Very high precision sensor even in extreme environmental conditions Use of a patented, high-performance natural ventilation protection screen: SMarT CELLino Sensor compliant with the performances prescribed by the WMO (guideline n°8 Annex 1.A) Optimal long-term stability Measure the dew and frost point

SMATRH is a combined sensor for measuring air temperature and relative humidity. Temperature measurement is taken using a platinum Pt100 resistance thermometer with a response curve compliant with the DIN 43760 Class 1/3 standard and with a 4-wire connection. The humidity measurement is obtained using a laser-cut capacitive polymer transducer connected to an electronic signal conditioning board. The sensor is offered either in the SMATRH-N version with natural output for temperature (4-wire Pt100) and 0-1 V output for humidity, or in the I, V, S, 12 versions (respectively in current, tension,...
