The LI200X Silicon Pyranometer is calibrated against an Eppley precision Spectral Pyranometer (PSP) to accurately measure sun plus sky radiation. LI200X is used extensively in solar, agricultural, meteorological, and applications. The LI200X should not be used under vegetation or artificial lights because it is calibrated for the daylight spectrum (400 to 1100 nm). Has standardised calibration, so individual sensors can be interchanged without altering the multiplier and offsetting values.
