Applications

CMP21 | CMP22 | SMP22

ISO 9060 & IEC 61724 Class A Fully compliant with ISO 9060:2018 spectrally flat Class A specifications, the CMP21, CMP22, and SMP22 provide solar irradiance measurements with highest accuracy and reliability. They are the sensors of choice for renowned research institutes around the world. Adding highest-quality quartz domes for a wider spectral range makes the CMP22 and the SMP22 the most accurate pyranometers available.

Minimized maintenance The CMP21 and CMP22 as well as the smart SMP22 are extremely robust pyranometers that have been designed to fulfill the highest requirements of scientific research.

The CMP21 and CMP22 have an easy-to-remove drying cartridge filled with easy-to-replace desiccant that is supplied in convenient refill packets. In contrast, the SMP is fitted with a maintenance-free internal desiccant that lasts at least 10 years.

Analog or digital outputs The CMP21 and CMP22 do not require any power. Incoming solar radiation generates a continuous millivolt output, which is converted in a data logger to irradiance in W/m² using the calibrated sensitivity. For easy integration into SCADA systems the SMP22 has Modbus® RTU RS-485 serial communication, plus an amplified analog output. A specific, individual polynomial correction function is stored in each SMP22.

5 years warranty All pyranometers from Kipp & Zonen come with a 5-year warranty and we have service and calibration centers around the world.
