The Fluke IRR2-BT Irradiance Meter Pro has been designed from the ground up to simplify the installation, commissioning, and troubleshooting of photovoltaic arrays, measuring irradiance, temperature, inclination and direction of the solar array in a single handheld tool. With a rugged, compact design, a protective carrying case, and an easy-to-read, high contrast LCD screen - for reading measurements in direct sunlight - these comprehensive PV site surveyors can go anywhere. The simple user interface, instantaneous solar irradiation measurements, and built-in temperature sensor make it easy to meet the IEC 62446-1 requirements for testing, documenting, and maintaining photovoltaic systems. Additionally, the integrated compass and inclination sensor allows the user to quickly measure and document roof and site orientation, pitch, and panel tilt while surveying, installing, or adjusting an installation.

Solar site survey all-in-one tool

From performing surveys and solar panel installation, to executing the maintenance and performance of photovoltaic systems, the IRR2-BT gives users the four critical measurements needed in one easy-to-use tool.

Convenient mounting bracket

The IRR2-BT comes with a convenient mounting bracket so that accurate solar irradiance and temperature measurements can be taken at the panel. Simply connect the bracket to the edge of a panel - then secure the external probe to the back of that same panel - for accurate readings.

Wireless connection with the SMFT-1000 Multifunction PV Analyzer (Sold Separately)

The Fluke IRR2-BT Solar Site Survey Irradiance Meter communicates wirelessly with the SMFT-1000 Multifunction PV Tester and Performance Analyzer to produce a highly accurate I-V curve instantly, making it easy to determine if a PV system is operating as designed. When the units are synced, irradiance and temperature measurements are instantaneously sent to the analyzer for easy recording while working in the field. The data record time is up to 17 hours.
