The Fluke IRR1 Irradiance Meter has been designed from the ground up to simplify the installation, commissioning and troubleshooting of photovoltaic arrays, measuring irradiance, temperature, and inclination of the solar array in a single handheld tool.

• Make the critical measurements needed for installing, testing, maintaining and reporting on solar panels or photovoltaic systems with one, easy-to-use tool.
• High precision mono-crystalline solar sensor: instantaneous irradiance measurements up to 1400 w/m2
• Two options for temperature measurement: use built-in temperature sensor or external suction mount temperature probe to measure ambient and panel temperature
• Integrated compass and inclination sensor: measure and document site and panel orientation and inclination
