GMX200 Wind Speed & Direction Sensor with Compass

The MaxiMet GMX200 is an ultrasonic wind speed and direction sensor with an electronic compass. This enables the unit to provide apparent wind measurements, average speed and direction together with WMO averages and gust data is also provided. The optional GPS also provide compensated wind speed and direction readings, making the instrument ideal for wind monitoring on vehicle and vessels. The data is output in serial formats – RS232, RS485. SDI12, NMEA and MODBUS.
