Visualize Overloaded Circuit Panels and Trace Mechanical Energy Friction Instantly with High Pixel Density Smartphone Infrared Imaging Matrix

Shop the Klein Tools TI223 mobile thermal imager engineered to adapt USB-C smartphones into high-resolution infrared diagnostic inspection cameras. This device captures 19,200 pixel matrix footprints across a temperature scale from -4°F to 752°F to evaluate structural panel anomalies and hidden fluid blockages. Operating via host phone power with a thermal sensitivity under 50 mK and an adjustable emissivity track, it isolates high-resistance wiring faults and energy transfer deficiencies through thick appliance cases without demanding structural component disassembly.

Best Used For:

  • Electrical Panel Scans: Interfacing with smartphone ports to isolate overheating circuit breaker lugs and unbalanced phases up to 752°F.
  • HVAC Duct Inspections: Mapping real-time thermal transfer leaks across insulation boundaries, air handler trunks, and furnace vents.
  • Mechanical Wear Diagnosis: Tracing friction-induced heat blooms in industrial motor bearings, pump shafts, and drive belt tracks.

Key Performance & Safety Features

  • 19200 Pixel Micro-Matrix: Dense focal plane sensor captures sharp structural heat gradients to pinpoint minor electrical resistance issues.
  • Case-Friendly USB-C Link: Elongated connector stalk slides securely into smart devices through shielding frames up to 1/5-inch thick.
  • High-Sensitivity Detection: Thermal resolution rating lower than 50 mK exposes minor environmental heat variations for micro-leak monitoring.
  • Differential Delta-T App Logic: Interactive interface app calculates maximum, minimum, and center-spot variances concurrently for fast site comparisons.
  • Anodized Metal Shielding: Rugged structural aluminum outer housing defends solid-state camera optics from jobsite contact wear.

What's Included

  • TI223 Mobile Thermal Imager (USB-C)
  • Hard Protective Storage Case
  • Aluminum Carabiner
  • Instruction Manual
