Description
Fully compliant with ISO 9060:2018 spectrally flat Class C and IEC 6174-1 Class C specifications, the CMP3 is a compact, light pyranometer that provides reliable and good quality data in a wide range of operational environments.
The CMP3 are robust pyranometers that have been designed to provide high quality measurements with little maintenance needs. The CMP3 has an easy-to-remove drying cartridge filled with easy-to-replace desiccant that is supplied in convenient refill packets.
The CMP3 does not require any power. Incoming solar radiation generates a continuous millivolt output, which is converted in a data logger to irradiance in W/m² using the calibrated sensitivity.
The following items are included with CMP3 Series pyranometers:
- CMP3 Pyranometer
- Sun shield
- 25m Cable, pre-wired with 2-pin connector
- Calibration certificate
- Instruction sheet
- Pyranometer fixing kit CMP3: 2 stainless steel screws each: M5 x 30mm, M5 x 40mm, M5 x 50mm; Nuts and flat washers
