Product Description

A digital pyranometer compatible with the Orbit 360 data logger.

The digital SR30 Pyranometer offers the highest accuracy and highest data availability: featuring new Recirculating Ventilation and Heating (RVH™) technology, SR30 outperforms all pyranometers equipped with traditional ventilation systems. It is the first pyranometer compliant in its standard configuration with Class A requirements of the new IEC 61724-1 standard. SR30 is “Secondary Standard” in the ISO 9060:1990 standard and “Spectrally Flat Class A” in the upcoming ISO 9060:2018 revision. It is the ideal instrument for use in PV system performance monitoring and meteorological networks.
