Paint thickness gauge Unit UT343D — handheld coating thickness meter, digital display

Unit UT343D is a handheld paint thickness gauge designed to measure the thickness of paint and other non‑magnetic coatings on ferrous and non‑ferrous metal substrates. The compact digital meter provides direct numeric readings on a clear display and combines portability with straightforward operation for fast on‑site inspections, vehicle paint assessment and basic quality control tasks.

Advantages

The Unit UT343D offers fast, non‑destructive measurement with a digital display that shows coating thickness in engineering units. Its handheld form factor and simple controls enable one‑handed operation during spot checks. The meter supports measurement on both ferrous and non‑ferrous metal bases using the appropriate measurement mode, ensuring versatility across automotive, industrial and maintenance applications. The device is battery powered for field use and is suitable for quick inspection routines.

Suitable for

• Vehicle paint inspection and pre‑purchase checks
• Workshop and bodyshop quality control of coatings
• Maintenance inspection of painted metal structures and equipment
• Spot checks during production and finishing processes

Key specifications

• Measurement principle: magnetic/eddy current methods for ferrous and non‑ferrous substrates
• Display: digital numeric readout for coating thickness values
• Measurement range: designed for paint and non‑magnetic coatings on metal
• Accuracy: suitable for rapid on‑site and workshop inspection tasks
• Power: battery operated for portable use
• Form factor: compact handheld meter with single‑hand operation

How to use

Switch on the Unit UT343D and select the appropriate measuring mode for the substrate (ferrous or non‑ferrous). Place the probe flat on the coated surface and hold steady until the digital readout stabilizes, then record the displayed thickness value. For reliable results, ensure the probe and surface are clean and free of loose particles or fluids. When measuring curved or narrow areas, position the probe carefully and take several measurements to confirm consistency.

Usage recommendations

Before measurement, verify zero calibration on a clean uncoated reference surface or use a supplied calibration standard if available. Avoid measuring over deep scratches, seams or areas with heavy surface contamination. Store the meter in a dry environment and replace batteries as needed to maintain consistent performance.
