GMX400 Weather Station for Temp, RH, Pressure & Precipitation

The MaxiMet GMX400 is a combined instrument mounted inside three double louvered, naturally aspirated radiation shields for the measurement of ambient temperature, humidity and pressure, and precipitation, with no moving parts. The results are high performance across each measurement over long periods of time.The data is output in serial formats – RS232, RS485. SDI12, NMEA and MODBUS.
