The CMP6, manufactured by Kipp & Zonen, is an ISO first-class pyranometer that monitors solar radiation for the full solar spectrum range. It connects directly to a Campbell Scientific datalogger and is commonly used for environmental monitoring, solar resource assessment, and solar power performance applications.Read More
The CMP6 measures solar radiation with a high-quality blackened thermopile protected by two glass domes. Its flat spectral sensitivity, from 285 to 2800 nm, makes it ideal for applications in natural sunlight, under plant canopies, in green houses or buildings, and inverted to measure reflected solar radiation.
A desiccant-filled drying cartridge prevents dew from forming on the inner sides of the CMP6's domes. Campbell Scientific also offers the CVF4 heater/ventilator that keeps its domes free from ice and dew.
The CMP6 includes a white snap-on sun shield that reduces the sensor's temperature. A bubble level and adjusting leveling screws enable the sensor to be leveled without using a leveling base.
The CMP6 produces a millivolt signal that is measured directly by a Campbell Scientific datalogger.

Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible products.
The CMP6 has a bubble level and two leveling feet, which allow it to be leveled without using a leveling base. This pyranometer mounts to a mast, crossarm, or pole (1.0 in. to 2.1 in. OD) via the CM255 or CM255LS mounting stand. The CMP6 should be mounted away from all obstructions and reflective surfaces that might adversely effect the measurement.
