Kipp&Zonen公司的CMA系列反照率傳感器是用來測(cè)量輻射和反照率的精密儀器,符合ISO9060和IEC60904國(guó)際標(biāo)準(zhǔn)。儀器的上下各有一個(gè)傳感器,上面的傳感器測(cè)量由大氣入射的太陽輻射,下面的傳感器測(cè)量由地表反射的太陽輻射。通過以上兩組測(cè)量數(shù)據(jù)即可測(cè)算出反照率。CMA6將兩個(gè)CMP6輻射傳感器集成于一體,可應(yīng)用在日常氣象、水文、農(nóng)業(yè)觀測(cè)研究等領(lǐng)域。CMA11則是整合了兩個(gè)CMP11輻射傳感器。我們建議在要求高的科學(xué)研究中使用該產(chǎn)品。
其配備的白色的太陽遮擋罩能有效避免儀器因太陽輻射而產(chǎn)生內(nèi)部升溫。圓錐形的強(qiáng)光屏蔽防止了日出日落時(shí)太陽的直接照射。內(nèi)部備有干燥劑來保證儀器內(nèi)部干燥。為了便于安裝維護(hù),信號(hào)電纜設(shè)有一個(gè)防水連接器。

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.
