The CMP series pyranometers are well known around the world for their high quality, durability and accuracy. The instruments do not require any power and are ideal for remote sites with limited power availability or for field studies. Each has an individual calibration factor/sensitivity to convert the mV output signal to W/m² of irradiance.
The CMP3 is a spectrally flat class C pyranometer that is smaller and lighter than the other CMP series pyranometers, providing an economical solution for the routine measurement of incoming global solar radiation. The CMP3 uses a 64-junction thermopile detectors and provides an expected output of 0-48mV based on a sensitivity of 24 to 32µV/W/m². The CMP3 has a 4mm glass dome with a spectral range of 300 to 2800nm. The small size and sealed construction make this instrument the ideal choice for horticulture, monitoring solar energy installations and small industrial applications.
The CMP6 Pyranometer is a Spectrally Flat Class B pyranometer that has a similar detector to the CMP3 but with improved performance. The CMP6 uses a 64-junction thermopile detectors and provides an expected output of 0-30mV based on a sensitivity of 5 to 20µV/W/m². The CMP6 has two, 2mm thick, high quality concentric domes which reduces directional error and improves thermal isolation. The CMP6 has a drying cartridge with replaceable desiccant. Spectral range of 285 to 2800nm. The CMP6 is ideal for cost-effective, good quality, measurements in meteorological, hydrological and agricultural applications.
The CMP10 Pyranometer is a Spectrally Flat Class A pyranometer which provides a faster response, better linearity and a wider measurement range than the CMP3 and CMP6. The CMP10 has been update to the CMP10X pyranometer. It maintains the improved thermopile detector, providing an expected output of 0-24mV based on a sensitivity of 7 to 16µV/W/m², but now includes a 10k Thermistor sensor for CJC of the thermopile detector. The CMP10X has two, 2mm thick, high quality concentric domes which reduces directional error and improves thermal isolation. The CMP10X has internal desiccant that lasts for up to 10 years. Spectral range of 285 to 2800nm. The sealed construction and 10 year desiccant pack can be replaced at the factory and...
The CMP21 Pyranometer is a secondary standard pyranometer that is similar to the CMP11 but has individually optimised temperature compensation. The CMP21 uses a 32-junction thermopile detector and provides an expected output of 0-20mV based on a sensitivity of 7 to 14µV/Wm². The CMP21 has two, 2mm thick, high quality concentric domes which reduces directional error and improves thermal isolation. The CMP21 has an internal 10K thermistor, or PT100, sensor to monitor the housing temperature, along with individual temperature and direction response values for post-processing of recorded data. The CMP21 also has a refillable desiccant chamber. Spectral range of 285 to 2800nm. The CMP21 is the choice for scientific use and in top level solar radiation monitoring networks, such as...
The CMP22 Pyranometer is a Spectrally Flat Class A pyranometer that uses very high quality quartz domes for a wider spectral range, improved directional response and reduced thermal offsets than the CMP21. The CMP22 uses a 32-junction thermopile detector and provides an expected output of 0-21mV based on a sensitivity of 7 to 14µV/Wm². The CMP22 has an internal 10K thermistor, or PT100, sensor to monitor the housing temperature, along with individual temperature and direction response values for post-processing of recorded data. The CMP22 also has a refillable desiccant chamber. Spectral range of 200 to 3600nm. The CMP22, with its high-quality quartz dome, provides a wider spectral range, making it the most accurate analogue pyranometer and sensor of choice for...
The CVF4 Ventilation unit is a low maintenance ventilation unit with a fan and inlet filter that provides a flow of clean air over the dome of a radiometer. The integrated heater allows the air to be warmed when necessary. The fan of the CVF4 runs continuously to reduce dust and dirt settling, to dissipate rain drops and to stabilise the dome temperature. A tacho output from the fan gives two pulses per revolution and allows remote monitoring of the fan operation using a data logger. The CVF4 is designed to be used with Kipp & Zonen CMP and SMP series pyranometers, the CGR 4 pyrgeometer, and the CUV5 total UV radiometer.
