Klein Tools Thermometer IR5 Dual Laser Infrared Temperature Gun (12 to 1 Distance Spot Ratio Adjustable Emissivity Non Contact Thermal HVAC Scanner)

Map Circular Measurement Areas and Analyze Component Differential Variances Instantly With Multi Laser Proximity Thermal Telemetry

Shop the Klein Tools IR5 dual laser infrared digital thermometer engineered for the rapid, non-contact evaluation of surface temperatures across electrical hardware and structural systems. This optical pyrometer captures accurate temperature parameters stretching from -22°F to 752°F, utilizing a precise 12:1 distance-to-spot optics array to map restricted targets from safe operational boundaries. Operating with an internal Class II dual laser targeting system that defines the circular measurement boundaries, the tool generates structural heat data sets in under 0.25 seconds across an adjustable emissivity scale to isolate high-resistance circuit anomalies instantly.

Best Used For:

• Electrical Panel Audits: Directing the optical lens toward branch circuit breaker lugs and distribution terminal steps to isolate high-resistance thermal loads.
• HVAC Performance Inspections: Mapping real-time thermal profiles at supply vents, heat exchangers, and air handler registers to balance climate zones.
• Variable Surface Scanning: Adjusting the digital emissivity scale to execute reliable non-contact testing across shiny copper lines or matte industrial steel enclosures.

Key Performance & Safety Features

• Dual Laser Orientation: Projects two visible optical lines to explicitly outline the active tracking circle area for absolute positioning confidence.
• 12:1 Optical Grid Resolution: Concentrates the target diagnostic boundary to focus precisely on small internal components from a comfortable field stance.
• Adjustable Emissivity Scale: Customizable radiation settings ranging from 0.10 to 1.00 compensate for variable material surfaces to maintain reading integrity.
• Advanced Calculation Modes: Onboard microcircuitry calculates maximum, minimum, average, and differential values alongside user-programmable audio-visual alarms.
• Concrete Ingress Resilience: High-impact industrial polymer housing assembly passes drop validation testing on hard commercial deck floors from up to 6.6 feet.

Technical Specifications

Pro-Tip: When shifting from dull oxidized metal enclosures to reflective raw copper lines, adjust the emissivity settings downward toward 0.10 to 0.30; matching the material emissivity is key to preventing low, inaccurate thermal readings.
