Meteorology
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.

The MET4 and fan-aspirated MET4A Meteorological Measurement Systems provide high accuracy data from barometric pressure, temperature, and relative humidity sensors. These fully-integrated systems are housed in environmental enclosures allowing indoor or outdoor mounting. Installation hardware and software are included and optional interface cabling is available. The MET4 solar radiation shield protects the temperature and humidity sensors from precipitation and solar radiation. Features and Specifications: • Pressure Accuracy: Better than ±0.08 hPa (0.001 psi) • Barometric Pressure Range: 500 – 1100 hPa (7 – 16 psi) • Temperature Accuracy: Better than 0.5°C (Met4) and better than 0.1°C (Met4A) • Relative Humidity Accuracy: ±2% at 25°C • Resolution: One-part-per billion
