Automatic Solar Tracker
Model SMT
The Eppley Automatic Solar Tracker, Model SMT was developed to allow convenient automatic pointing of normal incidence solar radiation measuring instruments (sNIP , AHF) at the sun. Due to its robust design, users have continued to expect solar trackers to do more and more and the SMT does not disappoint. Eppley offers an optional Shade Disk Kit that allows for shading and ventilation of pyranometers and pyrgeometers. During intercomparisons, it is common to see four or more AHF Cavity Radiometers on a single tracker.
