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.

Paroscientific manufactures a precision weather station called the MET4. This Broadband Meteorological Measurement System takes extremely accurate pressure, temperature, and humidity readings and logs over 200,000 data points for later retrieval. The MET4 makes use of a proprietary pressure port engineered to reduce the dynamic effects of wind on the barometric readings. The MET4A is a fan-aspirated model which provides greater accuracy and stability of the temperature and humidity readings over time. Barometric Range: 50 to 110 kPa Pressure Accuracy: 8 Pa or better Temperature Accuracy: Met4 ±0.5°C, Met4A ±0.1°C or better Relative Humidity Accuracy: ±2% at 25°C Achievable Pressure Resolution: 10 ppb or better
