80SPC Solar Radiation Pyranometer

The pyranometer consists of a temperature compensated photocell sealed in epoxy resin. The instrument is robust and weather-proof and is mounted on a single piece of 25mm thick Plexiglass.

Each sensor is calibrated by comparison with a WMO (World Meteorological Organization) Class 1 instrument. Daily Global radiation measurements typically agree to within +/-3% of a Class 1 device.

The 80-SPC is intended for use as a general purpose pyranometer to measure solar radiation. No signal amplification is required. The 80-SPC avoids the high cost normally associated with solar radiation sensors, and the high output signal enables an easy connection to most data acquisition equipment.
