KIPP ZONEN反照率测量仪CMA6

KIPP ZONEN反照率测量仪CMA6的详细介绍

KIPP ZONEN反照率测量仪CMA6是用来测量全球辐射的，也可测量来自许多不同表面的反照率。上面的传感器测量入射进来的总辐射，下面的测量地表反射的太阳辐射。通过以上两测量数据即可算出反照率。CMA 6可应用在日常气象研究，CMA 11则建议在要求高精确标准的科学研究上使用。
    轻量级设计使CMA成为理想的便携式测量仪器，如冰雪领域。白色的太阳遮挡罩避免仪器产生热量。圆锥形的强光屏蔽防止了日出日落时太阳直接照射。水平泡内部设有干燥剂来保证仪器内部干燥。为了便于安装维护，信号电缆设有一个防水连接器。

CMA 6 complies with the second highest level, First Class. CMA 6 is constructed around two CMP 6 pyranometer sensors. Both sensors are contained in a single housing and have matched sensitivities. The CMA albedometers are significantly lighter than the previous models due to the completely new design and mounting rod. The reduced weight is important in portable applications such as measurements over snow and ice fields for investigation of global warming effects.

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 signal cable has a waterproof connector for ease of installation.

All albedometers are supplied with a calibration certificate traceable to the World Radiation Centre.
