The CMP 11 Albedometer Kit is a step up in performance from the CMP 6 Kit and is recommended for scientific applications, for which accuracy needs to be according to the highest standards.
This ISO 9060:2018 Spectrally Flat Class A Albedometer Kit is ideal to define the ratio of irradiance reflected to the irradiance received by a surface (albedo). This results in a scale from 0 (no reflection) to 1 (total reflection).
By using two separate pyranometers with a mounting fixture (plate and rod) and a glare screen for the lower pyranometer, there is a choice of configurations available.
The CMB 1 mounting bracket can be used to fix the rod to a pole or wall.
If the CMF 1 mounting fixture is replaced by the CMF 4 model, the CVF 4 ventilation unit can be used with the upper and/or lower pyranometers. For the lower CVF 4 a special glare screen is available.
