GMX531 Weather Station – Wind, Temp, RH, Pressure, Solar & Precipitation

The MaxiMet GMX531 is a combined instrument mounted inside three double louvered, naturally aspirated radiation shields for the measurement of wind speed and direction, ambient temperature, humidity, pressure, solar radiation and rainfall utilising an external tipping bucket rain gauge (included). The data is output in serial formats – RS232, RS485. SDI12, NMEA and MODBUS.

Kalyx Rain Gauge

The Kalyx tipping bucket rain gauge provides excellent performance in tropical or heavy convective precipitation locations. The low power Kaylx connects via a 20 metre cable that the user can cut to length. The sensor has a tipping bucket mechanism which automatically tips when precipitation accumulates inside of it. Total precipitation is determined by the number of tips.

An adjustable mounting plate compensates for uneven surfaces and the unique aerodynamic shape of the rain gauge reduces the effects of wind blown rain being carried away from the collecting vessel. The tipping bucket includes a drain hole and does not need to be emptied.
