PYR1-420 is an ISO 9060:2018 Class B (First Class) Thermopile Pyranometer.

It is ideal for meteorological use or monitoring photovoltaic performance when this is a requirement in EPC and O&M contracts.
Note: the terms irradiance sensor, photovoltaic pyranometer, reference cell and solarimeter are interchangeable. On this site we will use photovoltaic pyranometer. To learn more click here.
