The GMX500 also measures wind speed and direction via an ultrasonic sensor which, with 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.
Features
Overview
A combined temperature, humidity, pressure, wind speed and direction 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.
