Manufactured by Kipp & Zonen, the SP-Lite is a silicium-pyranometer that can be used under all weather conditions. It is designed for calculating evapotranspiration for precision irrigation purposes, for air pollution dispersion calculations, and for monitoring solar panels in energy production. Under clear and unobstructed natural daylight conditions, the SP-Lite compares favorably to ISO 9060-specified First Class Thermopile Pyranometers. The SP Lite uses a photo diode detector, which creates a voltage output that is proportional to the incoming radiation. The signal is then converted by the integrated Adcon amplifier to a 0-2.5V signal, compatible to all Adcon RTU's. The sensor is supplied with all necessary mast mounting equipment, two pipe clamps, and a shielded 2m cable with a 7-pin Binder jack, compatible to all RTU's of the A723 and A733 families.
