Testo 872 Professional Thermal Imager with Laser & WLAN
The Testo 872 thermal imager provides unmatched support for high-end professional industrial thermography and building inspections. Delivering premium image quality and class-leading thermal sensitivity, it enables operators to execute precise non-destructive testing quickly and effortlessly. Incorporating cutting-edge testo SuperResolution, the native detector matrix scales up to produce ultra-sharp thermal images. Advanced on-board analytics such as testo ScaleAssist, testo ɛ-Assist, and the integrated laser marker eliminate common measuring errors by dynamically calculating target emissivity, reflected temperature coefficients, and ideal scale adjustments.
Industrial Applications
- Industrial & Mechanical Maintenance: Early identification of overheated mechanical connections, bearings, and drive components before failure occurs.
- Building Thermography & Energy Auditing: Precise pinpointing of structural defects, insulation gaps, air leaks, and thermal bridges.
- Smart Facility Management: Dynamic integration via Bluetooth with the Testo 605i thermohygrometer and Testo 770-3 clamp meter to immediately identify areas vulnerable to mold growth and monitor complex electrical sub-stations.
