Fluke IRR2-BT - Your Essential Solar Irradiance Meter

A rugged, one‑handed tool engineered for fast, accurate solar site surveys, the Fluke IRR2‑BT combines multiple critical measurements into a compact, easy‑to‑use instrument ideal for PV installers, maintenance technicians, and commissioning professionals.

Key Features

  • All‑in‑One Measurement: Simultaneously measures solar irradiance (50–1400 W/m²), ambient or panel temperature, panel tilt (inclination), and array orientation with an integrated compass.

  • Wireless Connectivity: Seamlessly pairs with the SMFT‑1000 Solar Multifunction PV Analyzer (sold separately) for instant, precise I–V curve readings during field diagnostics.

  • Field‑Ready Design: Features a high‑contrast LCD for readability in bright sunlight, a durable housing, and a panel‑mount bracket for hands‑free measurements. 

  • Long‑Term Monitoring: Built‑in memory holds up to 6,400 readings (~17 hours), with long battery life of ~50 hours using four AA batteries.

  • Comprehensive Orientation Tools: Inclination sensor covers –90° to +90° (±1.5° accuracy), and compass provides 0°–360° orientation (±7° accuracy), facilitating accurate roof tilt and orientation documentation.
