Description
The FNIRSI TDM-120P is a 2-in-1 thermal imaging multimeter that combines a 120×90 infrared thermal imager with a 19999-count True RMS digital multimeter in one pocket-sized device. The vanadium oxide detector delivers a 25Hz refresh rate with thermal sensitivity below 60mK, measuring temperatures from -20°C to 400°C (-4°F to 752°F) with ±2°C or ±2% accuracy. Emissivity is adjustable from 0.01 to 1 and the measuring distance is 0.5m to 3m. The imager includes automatic hot and cold spot tracking, dual cursor measurement (centre and floating), and high/low temperature alarms, so faults can be located quickly.
The multimeter side measures DC voltage up to 1000V (±0.5%+3) and AC voltage up to 750V (±1%+3). It also covers multi-range resistance, capacitance, continuity and diode testing, with data hold and real-time max/min display. The 2.8-inch LCD touchscreen offers 7 switchable colour palettes (Arctic, Hot Iron, Iron Red, Rainbow, Lava, Black Hot, White Hot). Images can be saved with one click to an SD card and exported over USB together with measurement data, which makes report-making and team sharing easy. The device charges over Type-C, supports Chinese and English, and can switch between °C and °F.
For HVAC technicians, electricians, electronics repair shops, automotive workshops and maintenance teams across Pakistan, the TDM-120P is a practical tool. In cities like Karachi, where AC systems, electrical panels and wiring run under heavy load through the hot months, a thermal imager spots overheating connections, failing components and cooling faults before they become breakdowns. Having the multimeter built in means one device can find the hot spot and then measure the circuit.
Why Choose the FNIRSI TDM-120P?
Pakistan’s workshops, electricians and facility maintenance teams often need two separate tools: a thermal camera for finding heat problems and a multimeter for verifying them. The TDM-120P combines both, so a technician can spot an overheating breaker, loose terminal or failing component on the thermal image and measure voltage, resistance, capacitance or continuity right away. That saves time on every job and gives a clearer picture of the fault. It suits AC and HVAC servicing, electrical panel and wiring inspection, PCB and electronics fault finding, water leak and insulation checks, and automotive diagnosis. The pocket-sized body and Type-C charging make it easy to carry on-site, and one-click image saving with USB export helps technicians document findings for customers and service reports.
