CMA 11 complies with the highest level of ISO 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. The screw-in drying cartridge is easy to remove and the replacement desiccant is supplied in convenient refill packets.The signal cable has a waterproof connector for ease of installation. All albedometers are supplied with a calibration certificate traceable to the World Radiation Centre.
