The heavy-duty Sun Tracker STR-32G completes the extensive EKO Sun Tracker range and is capable to take the highest load without compromising the typical high precision and performance of the STR. Similar to the STR-21G/22G it features a fully automated set up procedure through a GPS receiver, providing increased reliability and enhanced functionality. 

Even though the capacity load of the STR-32G is approximately 4 times more, the size hasn't changed. The most compact heavy duty sun trackers are perfectly suited to support all kinds of Global, Diffuse and Direct Radiation measurement sensors and spectroradiometers. Besides the standard EKO sensor mounts, various mounting options are available. 

From sunrise to sunset the compact EKO Sun-Tracker guarantees accurate sun tracking and pointing of …
