UNI-T UT343A Coating Thickness Gauge

UNI-T UT343A Coating Thickness Gauge in Sri Lanka

Compact Dual-Substrate DFT Meter

The UNI-T UT343A Coating Thickness Gauge measures paint, plating and other coatings on ferrous and non-ferrous metal, from 0 to 1750μm. It identifies the substrate automatically and measures without damaging the surface. This suits metal-processing, painting and quality inspection work in Sri Lanka. Browse our full range of coating thickness gauges in Sri Lanka.

It combines magnetic induction and eddy current sensing in one probe. The EBTN screen rotates for easier reading from different angles. A three-colour LED shows whether a reading is within your set limits, and the gauge stores 199 groups of readings. At 111g, it is easy to carry between the workshop and the field.

Buying Guidance

The UT343A works only on metal substrates. On non-ferrous metals, the coating must be non-conductive. Calibrate on an uncoated substrate similar to your workpiece, then take 5 readings at 3 to 5 points and average them. Very small, thin or tightly curved parts may fall outside the gauge's limits.
