Complete Guide to Landtek CM-8826FN Coating Thickness Measurement for Industrial Applications Malaysia

Introduction

Choosing a reliable coating thickness meter in Malaysia is an important part of industrial quality control, manufacturing inspection and protective coating maintenance.

Coating thickness measurement helps manufacturers, coating contractors and inspection teams evaluate whether paint, powder coating and protective finishing meet their required specifications.

Industries such as steel fabrication, aluminium manufacturing, automotive component production, powder coating and industrial maintenance regularly require coating thickness measurements.

However, different substrates, coating systems and inspection conditions require different measurement methods.

The Landtek CM-8826FN Coating Thickness Meter is a portable digital instrument designed for non-destructive coating thickness measurement on compatible metallic substrates.

It supports two measurement principles:

Fe - Magnetic Induction

NFe - Eddy Current

This dual-function capability makes the instrument relevant to users working with both ferromagnetic steel and suitable non-ferrous conductive metals such as aluminium.

The CM-8826FN also features an external probe configuration, allowing the operator to position the sensor separately from the main display unit.

This comprehensive guide covers the Landtek CM-8826FN, including measurement principles, industrial applications, product selection, dry film thickness inspection, calibration, troubleshooting and purchasing considerations.

It is intended for Malaysian engineers, QA/QC personnel, coating inspectors, manufacturing companies and industrial maintenance teams.

DFT inspection is commonly used in protective coating projects.

Typical Steel Structure Applications

Factory steel structures

Warehouse steelwork

Industrial platforms

Equipment supports

Fabricated steel structures

Protective-coated machinery frames

Why DFT Measurement Matters

Protective coating systems are specified to provide the intended performance under defined service conditions.

DFT inspection helps determine whether the applied coating thickness meets the project requirements.

Multi-Layer Coating Systems

A protective coating system may contain several layers.

For example:

Coating LayerIllustrative ThicknessPrimer75 碌mIntermediate Coat125 碌mTopcoat50 碌mTotal Nominal DFT250 碌m

These values are illustrative only.

The CM-8826FN can measure the combined thickness of compatible non-magnetic coating layers above a suitable steel substrate.

It cannot independently identify the thickness of each layer after the complete coating system has been applied.

Surface Roughness Considerations

Abrasive blast-cleaned steel surfaces have peaks and valleys.

This surface profile can influence magnetic induction coating thickness measurements.

For specified protective coating projects, ISO 19840 may be relevant to DFT measurement on rough steel.

The correct adjustment, correction and acceptance procedures depend on the applicable standard and project requirements.

Differences may result from:

Factory coating variation

Repainting

Repair materials

Different substrates

Component geometry

Measurement conditions

Important Limitations

The CM-8826FN does not directly measure paint thickness on plastic bumpers using standard Fe or NFe methods.
