The CMP21 is a high performance research grade pyranometer, and is fully compliant with all ISO 9060 spectrally flat Class A Instrument performance criteria (highest possible ISO pyranometer performance category).

The CMP21 pyranometer is designed for measuring the irradiance (radiant flux, Watt/m²) on a plane surface, which results from the direct solar radiation and from the diffuse radiation incident from the hemisphere above.

CMP21 has the same detector as the CMP11 and individually optimised temperature compensation. A standard thermistor sensor is fitted to monitor the housing temperature. Each instrument is supplied with its own temperature and directional (cosine response) test data.

It is the choice for scientific use and in top level solar radiation monitoring networks such as the BSRN (Baseline Surface Radiation Network) of WMO.

A waterproof socket is fitted for the signature yellow signal cable, which is available in a range of lengths pre-wired to the waterproof plug. The integral bubble level is raised to the top of the housing and can be viewed without removing the redesigned snap-on sun shield, which also covers the connector. The screw-in drying cartridge is easy to remove and the replacement desiccant is supplied in convenient refill packets.

The pyranometer does not require any power, it supplies a low voltage of 0 to 20mV in relation to the amount of incoming radiation. When a higher voltage level or a 4 to 20mA signal is required, the AMPBOX is the perfect solution.

Features / Benefits

  • ISO 9060 spectrally flat Class A 
  • Verified cosine response 
  • Verified temperature dependence
  • Low dome IR offset error
  • Excellent linearity
  • Fast response time
  • 5 year warranty
