Coating Thickness Meter install base UT343D — range 0–1250 µm, professional handheld gauge

The install base UT343D coating thickness meter is a professional handheld gauge designed to measure paint, lacquer and other non-magnetic coatings on magnetic and non-magnetic substrates. With a measurement range of 0–1250 µm, the UT343D delivers rapid, on-site thickness readings for quality control, surface inspection and routine maintenance. Its compact, portable design makes it suitable for both workshop and field environments while providing the essential functions needed for coating evaluation and verification.

Advantages

The UT343D offers a wide measurement range and supports measurement on both ferrous and non-ferrous substrates, enabling versatile application across different coating systems. The instrument provides quick digital readouts and stable measurements that help reduce inspection time. Its handheld format and ergonomic shape ensure comfortable single-handed operation during extended inspection tasks. The meter is built to provide reliable, repeatable results suitable for professional inspection workflows.

Suitable for

• Quality control in automotive and industrial painting
• Inspection of protective coatings on steel and aluminum structures
• Pre-delivery inspection and maintenance checks
• Corrosion protection verification and surface preparation assessment

Key specifications

• Measurement range: 0–1250 µm
• Measurement principle: magnetic and eddy current compatible for ferrous and non-ferrous substrates
• Display: digital readout for immediate thickness values
• Form factor: handheld, compact and portable
• Typical applications: paint, lacquer and non-magnetic coatings

How to use

Switch on the UT343D and select the appropriate measurement mode for the substrate type if the meter provides separate ferrous/non-ferrous settings. Place the probe perpendicular to the coated surface and hold it steady until the digital readout stabilizes. For best practice, perform multiple measurements across the area of interest and calculate an average thickness value to represent the coating system. Follow any calibration or zeroing routine described in the instrument manual before beginning a new measurement session or when changing substrate types.

Usage recommendations

Ensure the probe and surface are clean and free of debris or loose particles before measuring. When measuring on curved or rough surfaces, take additional readings and use the average to compensate for local variation. For consistent results, allow the meter to acclimate to ambient temperature and carry out periodic calibration checks against a traceable reference standard.
