The TDM-120P thermal imaging camera with TRMS multimeter is an advanced professional instrument that combines infrared thermal imaging technology with the functionality of a True RMS digital multimeter. Designed for electricians, maintenance engineers, HVAC technicians and industrial professionals, it provides a complete solution for accurate fault detection, preventive maintenance and electrical diagnostics.
Featuring a high-definition thermal imaging camera with a 120 × 90 infrared resolution and a high-performance vanadium oxide detector, the TDM-120P delivers clear thermal images in real time with a refresh rate of up to 25Hz. This enables users to quickly identify hot spots, overheating components, energy losses and temperature anomalies in electrical systems, industrial equipment and building services installations.
Its thermal sensitivity of less than 60mK, combined with adjustable emissivity and automatic tracking of maximum and minimum temperatures, ensures reliable temperature measurement across a wide range of applications. The extensive measurement range of -20°C to 400°C makes it suitable for both industrial and commercial environments.
In addition to its thermal imaging capabilities, the unit incorporates a 19,999-count True RMS multimeter capable of accurately measuring AC/DC voltage, resistance, capacitance, continuity and diodes. By combining electrical testing and thermal analysis in a single device, users can diagnose faults faster and improve maintenance efficiency.
The 2.8-inch LCD touchscreen display provides intuitive operation and allows thermal images to be viewed using seven selectable colour palettes. This makes temperature differences easier to interpret and helps technicians locate faults more quickly and accurately.
For enhanced reporting and record keeping, thermal images can be stored directly to an SD card and exported via USB. This facilitates the creation of inspection reports, maintenance documentation and the sharing of diagnostic data between teams.
Its compact pocket-sized design, rechargeable battery and convenient USB Type-C charging interface make the TDM-120P ideal for field work, on-site inspections and extended maintenance operations.
This professional thermal imaging camera with integrated True RMS multimeter is ideally suited for electrical inspections, industrial maintenance, HVAC diagnostics, water leak detection, air conditioning maintenance, industrial equipment testing, switchboard inspections and automotive fault diagnosis. It is the ideal solution for professionals seeking a thermal camera with multimeter capable of delivering accurate thermal and electrical measurements in demanding environments.
