    FLUKE IRR1-SOL Solar Irradiance Meter, 0 to 1400 W/m2

    # IRR1-SOL

    • Measure solar irradiance, ambient and PV module temperature, array orientation and tilt angles
    • Make instantaneous measurements to determine the watts per square meter solar irradiation, required by IEC 62446-1 standard
    • High contrast LCD with large numbers for easy readability in direct sunlight
    • High precision mono-crystalline solar sensor – instantaneous irradiance measurements up to 1400 W/m²
    • Two options for temperature measurement – use the built-in temperature sensor or the external suction mount temperature probe to measure ambient and panel temperature
    • Integrated compass – measure and document roof or site orientation
    • Inclination sensor – know roof and PV panel tilt when surveying, installing, or adjusting the installation
