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
