日本EKO-STR系列单/双臂太阳追踪系统可装载各种类型的太阳辐射表，具有世界上*优秀的追踪精度。重型STR-32G能承受4倍于STR-21G/22G的负载，约60kg。结合直接辐射表（DNI传感器），遮挡组件以及总辐射表可以测量直接和散射辐射分量。该系统在气象、环境、新能源和科学研究等领域拥有广泛的客户群。
为便于安装和精确的太阳追踪，所有的STR太阳追踪器都有一个内置的GPS接收器。自动设置的位置坐标和时间信息可用来计算和控制其精确的对准太阳。标准的四象限太阳传感器可以补偿任何几何定位偏差，这也使得测量更为精确。
【STR系列太阳追踪器优点】：
高精度：拥有世界上*高的精度和响应速度；
自带偏差补偿：标准四象限太阳传感器，可以补偿几何定位偏差，使得测量更为精确；
自动定位：自带GPS接收器，自动设置位置坐标和时间信息，使其精确的对准太阳；
时刻对准太阳：当太阳被云等遮挡时，追踪器通过计算准确的对准太阳运行路径；在太阳出现时，使得直射表随时对准太阳；
操作灵活：可以通过PC指令完全控制或监控追踪器运行状态；
免维护：拥有世界上*先进的动力传递装置，可长期免维护；由于采用无动力带传递，系统不会因为环境温度变化引起过紧或者松弛而无法正常工作；
高适应性：全天候，高稳定性；
低功耗：可使用太阳能板供电。
【部分用途介绍/Application Introduction】：
太阳直接辐射测量/Direct Normal Incidence (DNI)
利用STR-21G 太阳追踪系统和ISO-9060 First Class直接辐射表MS-56，此系统拥有世界上*快的响应速度。非常适合于CPV(Concentrated Photovoltaic) 和CSP(Concentrated Solar Power)系统评估，以及气象、环境科学研究。
光谱直接辐射/Spectral Direct Normal Incidence Irradiance
STR-21G太阳追踪系统和MS-700光谱辐射计，用于测量350-1050nm的光谱直接辐射。
STR-32G太阳追踪系统结合MS-710/712光谱辐射计，可以测量350-1700nm光谱范围的直接辐射。散射辐射测量/Diffuse Radiation (DHI)
