UNI-T UT343A Coating Thickness Gauge for Paint and Metal Inspection Malaysia
UNI-T UT343A Coating Thickness Gauge for Paint and Metal Inspection Malaysia
Content
When checking paint, coating or surface treatment thickness on metal, visual inspection alone is not enough. A coating may look acceptable but still be too thin, too thick or inconsistent across different areas.
The UNI-T UT343A Coating Thickness Gauge provides a quick, non-destructive way to measure coating thickness on both ferrous (Fe) and non-ferrous (NFe) metal substrates.
With a measuring range of up to 1750 μm, it is suitable for automotive inspection, metal fabrication, painting work, maintenance and general industrial quality control in Malaysia.
What Can the UNI-T UT343A Measure?
The UT343A is designed to measure non-magnetic coatings on ferrous metals and suitable coatings on non-ferrous metals.
Typical applications include:
Paint thickness on steel
Automotive body paint inspection
Coating on aluminium components
Powder coating inspection
Protective coating on fabricated metal
Surface finishing inspection
Maintenance and quality-control checks
Because it supports Fe and NFe substrates, one instrument can cover a wider range of metal inspection jobs.
Key Features of UNI-T UT343A
Measuring Range: 0–1750 μm
The relatively wide range makes the UT343A useful for more than very thin automotive paint measurements.
Automatic Fe / NFe Detection
The instrument can identify the metal substrate, making routine measurements faster and easier.
Single & Continuous Measurement
Single measurement is useful for individual inspection points, while continuous measurement helps when checking multiple locations across a surface.
MAX / MIN / AVG Functions
Instead of relying on only one reading, users can compare multiple measurements and evaluate coating consistency.
199 Data Storage
Useful when several measurement points need to be recorded during inspection.
μm / mil Units
Users can select the preferred measurement unit according to the job or specification.
Upper and Lower Limit Alarm
Limits can be set to help identify readings that fall outside the required coating thickness range.
Why Measure Several Points?
A single reading does not always represent the entire coated surface.
For example, when checking a painted steel panel, readings may be:
Point A: 112 μm
Point B: 116 μm
Point C: 114 μm
Point D: 168 μm
The noticeably higher reading at Point D may indicate an additional coating layer, repair work or another difference that requires further investigation.
For industrial inspection, taking measurements at several locations also helps identify uneven coating application.
Automotive Paint Inspection
The UNI-T UT343A can be used when inspecting vehicle body panels.
Comparing readings across the:
Bonnet
Doors
Roof
Fender
Boot
Other painted metal panels
can help identify unusual differences in paint thickness.
However, a coating thickness reading should be treated as inspection data rather than automatic proof of accident or repair history. Substrate material, original paint system, panel replacement and previous refinishing can all affect readings.
Industrial Coating Inspection
UT343A is also suitable for users working with:
Metal fabrication | Painting | Powder coating | Maintenance | Manufacturing | QA/QC | Equipment inspection
Checking coating thickness can help determine whether a protective or decorative coating has been applied consistently.
