The CMP22 is designed with ultra high quality quartz domes for a wider spectral range. This means the CMP22 comes with much improved directional response and reduced thermal offsets. The high optical quality of these domes enables the CMP22 to perform with a directional response of less than ±5 W/m².
Kipp & Zonen is confident that the CMP22 and SMP22 are the most accurate pyranometers currently available.
The CMP22 has individually optimized 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.
A waterproof cable connector socket is integrated for our signature Kipp & Zonen 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 CMP22 pyranometer does not require a dedicated power supply. It generates a low voltage output in the estimated range of 0 to 21 mV relative to an irradiance measurement range of 0 to 1500 W/m². When a higher voltage level or a 4 to 20 mA signal is required, the AMPBOX is the perfect solution.
