Overview
Enviro Test ConstructSolar radiation meter can be used as a primary standard direct radiation meter. Suitable for all kinds of harsh environments. Fast response and accurate automatic tracking. The tracking modes of the Solar Tracking System are sensor tracking and sun tracking. Sensor tracking mode is a real-time sampling by photoelectric converter, computer analysis and comparison of changes in solar light intensity, thus driving the mechanical mechanism to achieve solar tracking mode. Direct radiation tracking is more accurate.The direct radiometer is a first-class standard radiometer for measuring the radiation perpendicular to the sun’s surface.
