Solar Radiation Sensors / SR30-L
Overview
The SR30-L, an ISO 9060:2018 spectrally flat Class A (secondary standard) pyranometer manufactured by Hukseflux, features Recirculating Ventilation and Heating (RVH™) technology. As a standalone unit, the SR30-L is fully compliant with IEC 61724-1 standards, whereas other pyranometers would require external ventilation/heating units to be compliant. The SR30-L is an ideal instrument for solar resource and PV performance monitoring.
Benefits and Features
- Heated for high data availability, featuring RVH™ technology
- Compliant with IEC 61724-1:2017 Class A
- Remote sensor diagnostics

SR30 Example Program v.1 (2 KB) 10-12-2020
The example CR1000X program measures the SR30 sensor. The program will store the values if the result code is zero, which indicates a properly working sensor. If the result code is not zero, NANs will be stored for the measurements.
