The testo 875/881, advanced thermal imagers, use infrared radiation, to conduct energy / heat surveys, providing both visible and infrared hard-copy pictures of buildings for heat leakage analysis, of process equipment for analysis of temperature profiles - hot or cold spots and electrical switch gear for overheating. These same instruments can provide quantitative diagnostics of temperature differences as small as 0.1°C.

With testo 875 and 881 IR imagers you actually "see" heat…

• that seeps through walls, doors and windows due to poor construction, insulation or design;
• from a faulty electrical circuit about to fail or cause a fire;
• from friction in a failing bearing of a motor or compressor;
• or from the cooling created by moisture trapped in a wall or floor that starts mold growth.
