Fluke IRR2-BT Solar Irradiance Meter Pro

The Fluke IRR2-BT is a professional-grade solar irradiance meter built for accurate and efficient measurements in the field. Its high-contrast LCD screen ensures easy readability even in direct sunlight, and its rugged, portable design makes it suitable for a variety of solar site conditions. The device features a precision monocrystalline solar sensor for irradiance measurements up to 1400 W/m², as well as dual temperature measurement options—either via the built-in sensor or an external suction mount probe for ambient and PV module readings.

Equipped with an integrated compass and inclination sensor, the IRR2-BT provides fast and precise data for roof and panel orientation and tilt, critical for photovoltaic site surveying, installation, and adjustment. It also supports wireless communication with the SMFT-1000 Solar Multifunction PV Analyzer (sold separately) to instantly generate I-V curves and validate panel performance. By accurately measuring site irradiance and shading, technicians can ensure systems receive the proper energy to achieve expected DC voltage and power output.

This meter is ideal for commissioning, maintaining, and troubleshooting PV systems, helping professionals meet IEC 62446-1 compliance requirements while saving time and reducing errors in the field. Its combination of portability, precision, and wireless capability makes it a powerful tool for modern solar energy projects.
