The Gill MaxiMet GMX2400 is an extremely compact, robust and lightweight solution for accurately measuring rainfall, wind speed and wind direction.
The integrated optical rain gauge senses rainfall as it hits its surface automatically measuring the raindrops size and quantity. It then records the data from which it calculates and formats the output as if a traditional tipping bucket rain gauge in serial format. The result is an extremely accurate precipitation sensor that has no moving parts and requires virtually no maintenance.
Wind speed and direction are measured using a solid state ultrasonic sensor. An electronic compass comes as standard, calculating apparent wind, WMO wind averages and gust data. The optional GPS adds the benefit of a true wind measurement, height above sea level, latitude and longitude and simplifies installation by automatically locating the sensor position.
NOTE: This optical sensor provides a general Indication only of rainfall levels for use in situations where low maintenance is required. Use a tipping bucket gauge (ARG314 or Kalyx) or equivalent with a GMX MaxiMet sensor (e.g. GMX531, GMX550 and GMX551) where reference quality precipitation measurements are required.
Richard Paul Russell Ltd. can connect the sensor to the WeatherFile.com website where data can be viewed using any internet connected device and downloaded for detailed analysis in a .CSV file
