Paint Thickness Gauge BLOW 3083# (model UT343D) — handheld coating thickness meter

Handheld paint thickness gauge BLOW 3083# (model UT343D) is a compact coating thickness meter designed for non-destructive measurement of paint, primer and lacquer layers on metal substrates. The device provides quick, contact-based readings that help assess coating uniformity and identify areas that may require repainting or further inspection. Its portable form factor and straightforward operation make it suitable for on-site checks in automotive, industrial and maintenance environments.

Advantages

The meter delivers fast, repeatable thickness measurements with minimal surface preparation and a clear digital display for easy reading. Its handheld design and durable housing support use in workshop and field conditions, while calibration capability ensures measurement accuracy across ferrous and non-ferrous substrates. The instrument requires no destructive sampling, allowing users to preserve the original coating while obtaining reliable data.

Suitable for

• Automotive paint inspection and quality control
• Industrial maintenance and corrosion protection checks
• Pre-purchase vehicle inspections and bodywork assessment
• Surface preparation verification and repaint planning

Key specifications

• Measurement principle: contact probe for coating thickness
• Target substrates: ferrous and non-ferrous metal surfaces
• Typical measured layers: paint, primer, lacquer and other non-magnetic coatings
• Portable handheld form factor with ergonomic housing
• Digital display for numeric readout
• Calibration function for substrate-specific accuracy

How to use

Place the probe perpendicular to the painted surface and ensure stable contact before taking a reading. If necessary, clean the measurement area of loose debris or heavy contamination to avoid false results. Use the calibration feature following the manufacturer’s instructions to match the specific substrate type prior to critical measurements. Record multiple readings across the surface to identify variations in coating thickness and average values where appropriate.

Usage recommendations

For reliable results, perform a short warm-up if the instrument has been stored in extreme temperatures and allow it to acclimate to the working environment. Avoid measuring over thick dirt, rust or textured fillers. When assessing vehicles, compare readings across panels and near edges where coating thickness commonly varies.
