GVDA Digital Paint Thickness Tester

GVDA Coating Thickness Gauge
Car Paint Film Thickness Tester | 0–1300μm | Fe/NFe | Automotive, Metal, Ceramic Surfaces

The GVDA GD198 Coating Thickness Gauge is a precision instrument designed for non-destructive measurement of paint, plating, and coating thickness on both ferrous (Fe) and non-ferrous (NFe) metal surfaces.

Whether you’re inspecting automotive paint, industrial coatings, or metal treatments, this versatile tool provides accurate readings using advanced magnetic induction and eddy current technologies.

Operating Principle
F Probe (Magnetic Induction):
Measures non-magnetic coatings (e.g. chrome, copper, zinc, varnish, rubber) on magnetic substrates like iron/steel.

N Probe (Eddy Current):
Measures insulating coatings (e.g. paint, anodizing, ceramics) on non-magnetic substrates like aluminum, copper, brass.

Applications
Perfect for:

Automotive industry (paint depth checks, accident detection)

Metal fabrication & processing

Chemical & surface treatment industries

Quality control & inspection

Laboratory and field use

Ideal for coating verification, paintwork inspection, and material testing in manufacturing, workshops, and outdoor environments.

Key Features
High-precision integrated dual probe (F/N)

Continuous (CON) and Single (SNG) measurement modes

Micron-level precision

Self-calibration function for improved accuracy

Stores up to 20 data groups

Auto power-off after 15 minutes of inactivity
