CMP22 Pyranometer
CMP22 has all the features of CMP21 but uses very high quality quartz domes for a wider spectral range, improved directional response, and reduced thermal offsets. Because of the high optical quality of these domes the directional error is reduced below 5 W/m². Kipp & Zonen is confident that CMP22 is the best pyranometer currently available.
- Most accurate pyranometer currently available
- Includes thermistor for individually optimized temperature compensation
- Compatible with most Campbell Scientific dataloggers
- Integrated bubble level is visible without removing sun shield
- Desiccant-filled drying cartridge prevents dew from forming on the inner sides of the domes
