Pyranometer CMP22 – ISO 9060 spectrally flat class A

Pyranometer for Scientific research requiring the highest level of measurement accuracy and reliability.

  • Negligible thermal gradient zero-offset 
  • Lowest zero-offset due to FIR radiation 
  • Broad spectral range 200 to 3600 nm 
  • Directional error < 5 W/m²
  • 5-year warranty


CMP22 Pyranometer – Kipp and Zonen

The Kipp and Zonen CMP22 Pyranometer has all the features of CMP21 but uses an even higher-quality quartz dome. This provides a wider spectral range, improved directional response, and reduced thermal offsets. The directional error is reduced below 5 W/m².

CMP22 has individually optimised temperature compensation and 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.

The CMP22 is ideal for research-grade applications where accuracy is paramount.

The CMP22 pyranometer requires no power. Instead, it supplies a low voltage of 0 to 20mV, proportional to the quantity of incoming radiation.

When a higher voltage level or a 4 to 20mA signal is required, you can combine the pyranometer with an AMPBOX as an alternative.
