Fluke IRR1-SOL Solar Irradiance Meter simplifies the installation, commissioning, and troubleshooting of photovoltaic arrays. The device measures the irradiance (up to 1400W/m2), temperature, inclination, and direction of a solar array in a single handheld tool. The IRR1-SOL features a rugged, compact design, a protective carrying case, and an easy-to-read, high-contrast LCD screen to read measurements in direct sunlight. A simple user interface, instantaneous solar irradiation measurements, and built-in temperature sensor make it easy to meet IEC 62446-1 requirements for testing, documenting, and maintaining photovoltaic systems. Additionally, the integrated compass and inclination sensor allow users to quickly measure and document roof and site orientation, pitch, and panel tilt while surveying, installing, or adjusting an installation. FEATURES Measure solar irradiance, ambient and PV module temperature, array orientation, and tilt angles High contrast LCD with large numbers for easy readability in direct sunlight Make instantaneous measurements to determine the watts per square meter solar irradiation, required by IEC 62446-1 standard Includes convenient carry case with shoulder strap Fluke IRR1-SOL Solar Irradiance Meter comes with an external temperature probe (FLK-80PR-IRR) and a suction cup, carrying case with shoulder strap (C250), 4x AA alkaline batteries, and a user manual.
