Secondary standard pyranometer SR30-M2-D1

ISO 9060digital

Digital Class A (secondary standard) pyranometer with heating and tilt sensor Welcome to the next level in solar radiation monitoring! The all-digital heated SR30-M2-D1 offers the highest accuracy and highest data availability: using Recirculating Ventilation and Heating (RVH™) technology, SR30 outperforms pyranometers equipped with traditional ventilation systems. SR30 is the ideal instrument for use in PV system performance monitoring and meteorological networks. It measures the solar radiation received by a plane surface, in W/m², from a 180 ° field of view angle. SR30 is an ISO 9060 spectrally flat Class A (previously “secondary standard”) pyranometer. It is employed where the highest measurement accuracy is required.
