The CMA11 sensor is a Secondary Standard albedometer used for measuring the ratio of the diffuse reflection of solar radiation to the total incoming solar radiation. The CMA 11 is equipped with a broadband thermopile detector and a double glass dome as well as an integrated bubble level and sun shield to prevent excessive heating of the body. The CMA 11 is supplied with a calibration certificate.
