MeteoTemp (Temp, Hum, Pres)_Mertani_Mertani Instruments
MeteoTemp (Temp, Hum, Pres) (MTI.AWS.BR.MT) 3-in-1 sensor combines ultra-low power pressure sensor with WMO temperature and humidity MeteoTemp RH+T has proven to have one of the lowest measurement uncertainties in the market for combined temperature and humidity measurement. A high-quality sealed barometric pressure sensor adds unbeatable value to the already exceptional MeteoTemp RH+T. Combined output features temperature, humidity, dew point, frost point & barometric pressure data. Ultra-low power performance is not affected by the addition of pressure sensor. Total combined power consumption remains around 800 µA, with the addition of only 20 µA by the pressure sensor to maintain the 5x advantage over most meteorological temperature and humidity probes.
 
 
3 sensors in 1 simplify your systems and extend battery life
•  Remove self-heating from your measurement data
•  Excellent value with easy re-calibration and traceability features
•  Lightning protection for ultimate reliability of air-temperature measurement
