A. Product Overview

The Metrix Plus Coat Gauge Pro xL is a professional digital coating thickness gauge developed for industrial coating inspection and quality control applications.

It can measure coatings on two major types of substrates:

Ferrous substrates: Iron, steel and other magnetic metals

Non ferrous substrates: Aluminium and other conductive non magnetic metals

The instrument combines magnetic induction and eddy current measurement technologies, allowing one coating thickness gauge to work with both ferrous and non ferrous materials.

Its extended measuring range of 0 to 3000 micrometers makes it suitable for thin protective coatings as well as comparatively thick industrial coating systems.

Key Specifications

The instrument also features a negative dot matrix color display, calibration guidance, non metallic and over range prompts, galvanized plating detection and metal putty detection.

B. Working Principle

The Metrix Plus Coat Gauge Pro xL automatically uses different measurement principles according to the substrate being tested.

Magnetic Induction Principle

For ferrous substrates such as iron and steel, the instrument uses the magnetic induction principle.

The integrated probe creates a magnetic field between the probe and the metal substrate. A coating such as paint, powder coating or another non magnetic layer changes the magnetic interaction between the probe and the base metal.

The instrument calculates this change and converts it into a coating thickness reading.

Typical applications include:

• Paint on steel

• Powder coating on steel

• Protective coatings on iron

• Galvanized surfaces

• Lacquer coatings

• Industrial protective coating systems

Eddy Current Principle

For non ferrous conductive substrates such as aluminium, the instrument uses the eddy current principle.

The probe generates an electromagnetic field that creates eddy currents within the conductive metal substrate. The presence and thickness of the non conductive coating affect the electromagnetic response.

The gauge measures this change and calculates the coating thickness.

Typical applications include:

• Paint on aluminium

• Anodized coatings

• Lacquer on aluminium

• Protective coatings on non ferrous metal

• Industrial coatings on aluminium components

Metrix specifies magnetic induction for non magnetic coatings on magnetic substrates and eddy current measurement for non conductive coatings on non magnetic substrates.

C. Why Is the Metrix Plus Coat Gauge Pro xL Used?

Coating thickness can directly influence corrosion protection, coating durability, appearance, adhesion, production cost and overall product quality.

If a coating is too thin, it may not provide the required protection or service life.

If a coating is too thick, it may increase coating consumption and production cost and could potentially contribute to coating defects depending on the coating system.

The Coat Gauge Pro xL allows users to check coating thickness without cutting or damaging the coated component.

Common Applications

It is suitable for measuring:

• Paint thickness

• Powder coating thickness

• Galvanized layer thickness

• Chrome layer thickness

• Anodized layer thickness

• Lacquer thickness

• Epoxy coating thickness

• Electroplating thickness

• Protective industrial coatings

The manufacturer specifically lists paint, galvanized layers, chrome layers, anodized layers, lacquer, epoxy, powder coatings and other electroplating applications on ferrous and non ferrous substrates.

Additional Inspection Benefits

The Pro xL also provides features that are useful for professional inspection work.

Statistics: Displays maximum, minimum, difference and average readings.

Grouped data storage: Stores measurement data in groups for comparison and documentation.

Galvanized plating detection: Helps identify galvanized surfaces.

Metal putty detection: Provides a notification where metal putty may affect thickness measurement.

Non metallic detection: Alerts the operator when measurement conditions are unsuitable.

Over range indication: Warns when the measured coating exceeds the instrument's supported range.

On screen calibration guide: Helps simplify the calibration procedure.

D. Suitable Buyers

The Metrix Plus Coat Gauge Pro xL Digital Coating Thickness Gauge is suitable for professionals and organizations that need to inspect coatings on both ferrous and non ferrous metal components.
