The Gill MaxiMet GMX100 is an extremely compact, robust and lightweight solution for accurately measuring precipitation. 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, requires virtually no maintenance and when linked to the WeatherFile website will automatically record data that can be viewed from any internet connected device.
NOTE: The Optical Sensor provides a General Indication only of rainfall levels for use in situations where low maintenance is required. Use a tipping bucket or equivalent with a MaxiMet (e.g. GMX531, GMX550 and GMX551) where reference quality precipitation measurements are required.

Users can check operation of the rain gauge by performing a simple test of functionality by spraying some water using a mist nozzle similar to that used in many households for watering plants. The MaxiMet rain gauge should register incremental rain fall when sprayed with water.
