Spot overheating circuits instantly. The FNIRSI TDM120 thermal camera multimeter merges precise electrical measurements with crisp infrared imagery. Identify wiring anomalies swiftly. Inspect machinery safely. Save diagnostic frames directly to a compatible SD card. Purpose built for experienced electricians, plant engineers, and maintenance teams seeking reliable dual-mode diagnostics. This rugged handheld unit tracks hot spots automatically and switches seamlessly between voltage testing and heat mapping.
Key Features
-
Dual Capability: Integrates active thermal imaging with comprehensive digital multimeter testing in a single handheld chassis.
-
Clear Visualization: Delivers twelve thousand eighty horizontal by ninety vertical infrared pixels updated twice per second.
-
Comprehensive Ranges: Measures direct currents up to one thousand volts and alternating currents up to seven hundred fifty volts.
Product Description
You receive two professional instruments merged into one portable enclosure. The embedded vanadium oxide detector paints real-time surface temperatures while the dedicated circuit board captures live electrical values. Flip between thermal viewing and electrical probing without swapping accessories. Adjust the emissivity slider to match reflective metals or painted surfaces. Your daily checks move faster because sight and measurement arrive together.
Product Overview
Designed for rapid field diagnostics, this device bridges visual heat tracking with precise numerical readings. Technicians rely on it to locate failing components before catastrophic breakdowns occur. The streamlined interface removes guesswork from complex wiring layouts. Every inspection yields measurable proof stored directly in removable memory.
Key Benefits
Stop wasting hours isolating intermittent shorts. Automatic maximum and minimum tracking draws your eye straight to trouble zones. Program alarm thresholds to trigger instant alerts when temperatures climb past safe operating limits. Navigate menus quickly through the responsive four-point-seven inch diagonal display. Archive timestamped reports for client handoffs or regulatory compliance.
Features
-
Color Palettes: Toggle between Arctic, Hot Iron, Iron Red, Rainbow, Lava, Black Hot, and White Hot themes.
-
Auto Range: Adapts test ranges dynamically so you never manually switch dials mid-inspection.
-
Hotspot Tracking: Continuously highlights peak and valley temperature coordinates on screen.
-
Bilingual Interface: Switches instantly between Chinese and English menu languages.

5 Frequently Asked Questions
Can I save multiple screenshots at once? The internal storage reserves frames sequentially until the card fills. Export files daily to keep reporting timelines steady.
Does the multimeter section work independently? Yes. You can perform isolated electrical tests without engaging the thermal sensor to conserve power.
Is the screen readable in bright sunlight? The eight-hundred-thirty-two by four-hundred eighty pixel matrix delivers adequate contrast for outdoor shade use.
How do I adjust for shiny materials? Dial the emissivity value upward through the temperature settings menu. Reflective surfaces read cooler until properly calibrated.
What covers warranty claims internationally? CE marking confirms European safety compliance. Regional distributors handle extended protection programs directly.
