GMX 531 Features
Temperature, humidity, pressure. A combined instrument mounted inside three double louvered, naturally aspirated radiation shields with no moving parts. The results are high performance across each measurement over long periods of time.

Solar radiation. An integrated solar radiation sensor/pyranometer. This highly accurate instrument uses a thermal sensor mounted at its base and protected by a single glass dome to record the amount of light in watts per metre². It is widely used in agro-meteorological applications and for monitoring the performance of solar panels.

Wind. Wind speed and direction measurements are provided via an ultrasonic sensor and the addition of an electronic compass provides apparent wind measurements. Average speed and  direction together with WMO averages and gust data is also provided. Add GPS (optional) to
provide true wind and other features.

Precipitation. The Kalyx tipping bucket rain gauge supplied provides in tropical or heavy convective precipitation locations. The low power

Kalyx Rain Gauge Features

Precipitation. 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 effectes 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.
