Overview
MX2309将研究级传感与无线便捷性相结合，集成了知名的LI-COR LI-200R总辐射表，可提供科学级精度的太阳辐射测量（典型校准不确定度为±3%）。
这款一体化设备结合了外部LI-200R总辐射表（测量400–1100 nm范围内的总太阳辐照度）和内置温湿度传感器，可全面捕捉气候状况。这使其能够计算关键指标，如累计太阳辐射（MJ/m²）、日光积分（太阳DLI，MJ/m²/天）、蒸气压亏缺（VPD，kPa）和露点。MX2309是一款坚固耐用的电池供电记录仪，以经济实惠的价格提供实验室级别的太阳气候条件测量，部署便捷，可将监测能力扩展到更广泛的环境和能源应用领域。
重要提示：安装时需要M-PLT和2003S调平装置。安装在杆子或管道上需要M-BRK和2003S。
用户可在现场安装传感器，设置和数据检索简单无缝——使用手机或平板上的免费HOBOconnect应用程序，无需电缆或额外的下载设备。通过蓝牙（最远100英尺范围）轻松配置记录仪并下载数据，让您能够在难以触及的地点部署和下载数据。
通过添加MX数据计划扩展您的远程监控，该计划允许您将数据上传至LI-COR Cloud远程软件，以进行进一步分析、共享等操作。
