Main Features:
- ISO 9060 spectrally flat Class A
- 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 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.
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.
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.
