FNIRSI TDM-120 termocamera, 120x90 IR, LCD 2,8 inch, da -20°C a 400°C, IP54

When electrical panels, HVAC systems, or building envelopes fail, the cause often hides as a temperature difference too subtle to see. The FNIRSI TDM-120 puts infrared vision in your hand, revealing hot spots, cold leaks, and failing components before they become costly repairs.

Who is it for

Electricians, HVAC technicians, facility maintenance crews, and DIY enthusiasts who need a quick, reliable thermal readout without a large investment. Its compact body slips into a toolbox, and the intuitive interface makes it easy to capture and analyze thermal images on the spot.

Tips

Adjust the emissivity setting based on the surface you are inspecting—polished metal requires a lower value, while painted or plastic surfaces work well near 0.95. Use the laser pointer to mark the exact component you are measuring, and capture images in multiple palettes to spot temperature patterns quickly.
