If you’re surveying, installing, executing maintenance or testing performance of solar panels or a photovoltaic system, the Fluke IRR1-SOL Irradiance Meter provides the 4 critical measurements needed all in one single easy-to-use tool. Make immediate measurements to determine the watt per square meter solar irradiation, required by IEC 62446-1 standard. Take temperature measurements by either placing the meter directly on the panel or by connecting the external probe. Discover cardinal direction with the compass, and confirm inclination of a roof or panel with the tilt function. Get all the crucial photovoltaic measurements needed to install, verify and report on the performance of a photovoltaic system in one instrument.
