Detailed Overview

This is a handheld coating thickness gauge featuring an integrated F (ferrous) probe and N (non-ferrous) probe. It automatically measures the thickness of non-magnetic coatings on steel (F) or non-conductive coatings on non-ferrous metals (N). The F/N combination provides a fast, universal solution for verifying coating thickness for corrosion protection and quality control.

Entry-level combined gauge for measuring coating thickness on both ferrous and non-ferrous metals.

• This dual-purpose gauge automatically identifies the substrate (magnetic steel or non-magnetic metal) and uses the appropriate method (Magnetic Induction or Eddy Current) to measure the thickness of paint, coatings, or galvanization.
• It is an essential QC tool for surface preparation and coating application, ensuring compliance with specifications like ISO and ASTM.
• The package includes the gauge unit, a set of calibration foils, and a zero substrate block.
• The integrated probe design allows for quick, single-handed operation.

Top Features & Benefits

• Coating thickness gauge measuring both Ferrous (F) and Non-Ferrous (N) substrates.
• Uses magnetic induction (F) and eddy current (N) principles within a single, integrated sensor.
• Features an integrated probe for robust, one-piece portability.
• Automatic substrate recognition for fast and error-free measurements.
• High measurement precision with resolution down to 0.1 micron.
• Digital LCD display with backlight for clear readings.

Primary Uses & Functions

A gauge used to measure the thickness of non-magnetic coatings on magnetic substrates (Fe) and non-conductive coatings on non-magnetic substrates (NFe). Its primary function is to provide rapid, non-destructive coating thickness verification in the field.
