Precipitation: An optical rain gauge that senses water hitting its outside surface and takes measurements based on the size and number of drops.
Wind Speed and Direction: Measurements are provided via an ultrasonic sensor and the addition of an electronic compass.
Temperature, Humidity and Pressure. A combined instrument mounted inside three double louvered, naturally aspirated radiation shields with no moving parts.
Temperature, Humidity, Pressure and Solar Radiation: The GMX300 with an integrated solar radiation sensor/pyranometer.
Temperature, Humidity, Pressure and Precipitation: The GMX300 with an integrated optical rain gauge.
Temperature, Humidity, Pressure with Wind Speed and Direction: The GMX300 with an integrated ultrasonic wind sensor.
