CMP 6 Spectrally Flat Class B Pyranometer with 10m Cable
  • CMP 6 Spectrally Flat Class B Pyranometer with 10m Cable


Quick Overview

CMP 6 Spectrally Flat Class B Pyranometer. Two, 2mm thick, high quality concentric domes. Integrated levelling. Sun shield. Spectral range 285-2800nm, response time less than 18 sec (95%), Operating temperature -40 to +80°C. Thermopile detector. Sensitivity 5 to 20µV/Wm². Supplied with waterproof 2-pin plug connector with 10m of pre-wired yellow signal cable.


Fully compliant with ISO 9060:2018 spectrally flat Class B specifications, the CMP6 delivers excellent spectral absorption and long-term stability characteristics. Compared to the CMP3 model, these instruments provide improved performance due to the increased thermal mass and the double glass dome construction.

The CMP6 are robust pyranometers that have been designed to provide high quality measurements with little maintenance needs. The CMP6 has an easy-to-remove drying cartridge filled with easy-to-replace desiccant that is supplied in convenient refill packets.

The CMP6 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 CMP6 Series pyranometers:

  • CMP6 Pyranometer
  • Sun shield
  • 10m Cable, pre-wired with 2-pin connector
  • Calibration certificate
  • Instruction sheet
  • Pyranometer fixing kit CMP6: 2 stainless steel screws M5 x 80mm; Nuts and flat washers; Nylon insulation ring
  • 2 desiccant bags for CMP6
  • CD-ROM with product documentation
