The CMP 3 Pyranometer offers an economical solution for the routine measurement of incoming global solar radiation (0.3 - 2.8 µm spectral range), or surface reflected solar radiation measurements.
The CMP 3 pyranometer is an instrument for measuring the solar irradiance. The thermopile sensor construction measures the solar energy that is received from the total solar spectrum and the whole hemisphere (180 degrees field of view). The output is expressed in Watts per meter square. The CMP 3 pyranometer is designed for continuous indoor and outdoor use.
CMP 3 is smaller and lighter than the other CMP Series pyranometers. It has a robust 4 mm thick glass dome to protect the thermopile from external influences. The small size and sealed construction make this instrument the ideal choice for horticulture, monitoring solar energy installations, industrial applications, and it can be used underwater.
The CMP 3 is fully compliant with all ISO-9060 Second Class pyranometer performance specification criteria. It is intended for shortwave global solar radiation measurements in the spectral range from 310 to 2800 nm. The thermopile detector measures irradiance up to 2000 W/m² with response time <18 seconds and typical sensitivity 10 µV/W/m² that varies less than 5 % from -10 ºC to +40 ºC.
Operating temperature range is -40 ºC to +80 ºC and the stability is better than 1 % per year.
The CMP 3 pyranometer features a snap-on white sun shield, integrated leveling and a weatherproof connector which is supplied pre-wired with 10 m of signal cable for simple installation. An optional mounting rod and longer cable lengths are available. Two CMP 3s can easily be mounted back-to-back to make a low-cost albedometer
