  • MaxiMet GMX500 Weather Station

GMX500 Weather Station for Wind, Temp, RH & Pressure

Quick Overview

The MaxiMet GMX500 is a combined instrument mounted inside three double louvered, naturally aspirated radiation shields for the measurement of wind speed and direction, ambient temperature, humidity and pressure, 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.
