FNIRSI TDM-120P Thermal Imager with True RMS Multimeter

The FNIRSI TDM-120P is a compact thermal imager for inspecting temperature patterns, hotspots and abnormal heating across electrical equipment, machinery, HVAC systems and other equipment or surfaces. Its 120 × 90 infrared detector produces radiometric thermal images across a -20 °C to 400 °C measurement range, with adjustable emissivity and measurement parameters for different surfaces and inspection conditions.

What distinguishes the TDM-120P from the related TDM-120 is an integrated 19999-count True RMS multimeter. AC/DC voltage, resistance, capacitance, continuity and diode measurements can be performed from the same handheld instrument, making the TDM-120P particularly useful where electrical condition and thermal behaviour need to be investigated together.

Thermal inspection

The vanadium-oxide thermal detector provides 120 × 90 infrared resolution, a 50° field of view and a frame rate up to 25 Hz. Centre temperature plus automatic high- and low-temperature tracking help identify significant temperature differences within the scene.

Seven thermal palettes provide different ways to inspect thermal patterns. Emissivity is adjustable from 0.01 to 1.00, with reflected-temperature and distance settings available to support measurement configuration.

The TDM-120P has thermal sensitivity of <60 mK and temperature accuracy of ±2 °C or ±2%, subject to applicable measurement conditions.

Integrated electrical measurement

The TDM-120P incorporates a 19999-count True RMS multimeter supporting AC and DC voltage, resistance, capacitance, continuity and diode testing, together with HOLD and minimum/maximum measurement display.

Image capture and review

Thermal images can be saved to SD storage and exported by USB. The inStore supplied configuration includes a 32 GB SD card.

Portable inspection

A 2.8-inch touchscreen provides thermal-image and measurement control in a compact handheld format. The TDM-120P includes USB-C charging, a manufacturer-stated 1500 mAh battery, adjustable display brightness and a foldable stand.

Typical applications

• Electrical equipment and panel inspection
• Hotspot and abnormal-heating investigation
• Equipment maintenance and fault-finding
• HVAC inspection
• Automotive diagnosis where thermal behaviour is informative
• Thermal inspection of equipment, systems and surfaces
• Diagnostic work where thermal and electrical measurements are useful together

Thermal imaging may also assist investigation of conditions associated with leakage, insulation or moisture where those conditions produce a meaningful temperature difference. This should not be interpreted as direct leak detection independently of thermal evidence.

Thermal measurement note

Infrared temperature measurement depends on factors including the emissivity of the measured surface and measurement conditions. Appropriate emissivity and related settings should be selected for the material and inspection context.
