UNI-T UT343A Coating Thickness Gauge
The UNI-T UT343A coating thickness gauge is a compact, handheld instrument designed to make non-destructive coating checks fast and intuitive. It combines magnetic-induction and eddy-current sensing to automatically adapt to ferrous or non-ferrous substrates, so inspectors can quickly verify paint, plating, or other coatings without damaging the part. The unit’s rotatable color display and clear readout help users take accurate readings from awkward angles and keep work moving.
Engineered for shop and field environments, the UT343A emphasizes ease of use and durability. Its simple button layout and rapid refresh make it straightforward to perform single-point or continuous measurements, while audible and LED alarms call out values outside user limits. The gauge’s memory and statistical modes let technicians capture and review measurement sets on the fly, supporting routine inspection or quality-control workflows.
Lightweight and battery-powered, the UT343A ships with calibration foil sets and reference substrates so users can verify accuracy immediately. Its robust sensor, drop resistance, and automatic substrate identification make it a practical choice for manufacturing inspection, paint shops, and maintenance teams who need repeatable, trusted thickness data.
Features:
- Measures coatings on both ferrous and non-ferrous substrates (FE/NFE).
- Automatic substrate identification and selectable probe modes (Auto/FE/NFE).
- Single and continuous measurement methods with MAX/MIN/AVG statistical modes.
- High-capacity memory storing up to 199 groups of data.
- Rotatable EBTN color screen for easy viewing from different angles.
- LED (3-color) warning lamp and audible buzzer for high/low alarms.
- Single-point and multi-point calibration using supplied standard coating sheets.
- Auto power-off and low-battery indication for longer field use.
