CMA11 Albedometer

CMA11 complies with the highest level of ISO 9060:1990 classification, Secondary Standard is recommended for scientific applications, for which accuracy needs to be according to the highest standards. The lightweight design makes CMA albedometers ideal for portable applications such as on snow and ice fields

The white sun shield prevents the body of the albedometer from heating up. The conical lower glare screen prevents direct illumination of the lower glass dome at sunrise and sunset.

A bubble level is fitted and a screw-in drying cartridge keeps the interior free from humidity.
