Technel represents Paroscientific which manufactures the MET4A, a fan aspirated meteorological measurement system that includes barometric pressure, temperature and relative humidity. The barometric pressure accuracy is better than 80 ppm over the barometric range and features the excellent stability and reliability of all the Paros barometers. The system temperature accuracy is better than ±0.2 deg C from -50 to +60 deg C.  The RH system accuracy is better than 2% RH from 0-100 %RH at 25 deg. C. The humidity recovery time after saturation is less than 20 seconds which is very important for measurements near or on the water.
