FNIRSI TDM-120P Thermal Imaging Camera with 2.8-inch Display, 120x90 IR Resolution, Temperature Range -20°C to 400°C

Uncover hidden temperature anomalies with the FNIRSI TDM-120P, a compact handheld thermal imaging camera engineered for rapid diagnostics. Combining a 120x90 pixel infrared sensor with a wide -20°C to 400°C measurement range, this tool lets you spot overheating components, insulation gaps, and electrical faults with confidence. Its 25 Hz refresh rate ensures smooth real-time imaging, while the bright 2.8-inch TFT display presents every thermal detail clearly.

Advantages

The TDM-120P excels in demanding environments: its rugged IP54-rated housing and 2-meter drop protection are built for field work. The adjustable emissivity (0.01–0.99) improves accuracy on various surfaces, and seven colour palettes (Iron Red, Rainbow, White Hot, Black Hot, Lava, High Contrast Rainbow, Red Hot) help you interpret temperature gradients effortlessly. Onboard 4GB storage stores JPG images with embedded temperature data, and USB-C charging provides up to 8 hours of continuous operation.
