Laklaagdiktemeter BLOW GL-8S FE&AL 50-483# — meet ijzer- en aluminiumcoatings

The BLOW GL-8S FE&AL 50-483# is a compact paint thickness gauge designed to measure coating thickness on ferrous (FE) and aluminium (AL) substrates. It delivers quick, non-destructive readings for paint, lacquer and powder coatings, enabling fast assessment of surface treatment and verification against specifications. The device is suitable for workshop inspections, vehicle appraisal, maintenance checks and industrial quality control where reliable thickness data is required.

Advantages

The gauge offers dual-mode measurement for both ferrous and aluminium substrates, reducing the need for multiple instruments. Readings are taken rapidly and without damaging the coating, which helps preserve the tested surface. Its compact form factor supports handheld operation and easy positioning on curved or flat surfaces. The instrument provides consistent, repeatable results that aid decision-making during inspection, repair and quality control tasks.

Suitable for

• Automotive paint inspection and vehicle valuation
• Industrial coating quality control and shopfloor checks
• Maintenance and refurbishment assessment of metal structures
• Pre-purchase inspections to detect uneven or repainted areas

Key specifications

• Measurement range suitable for ferrous and aluminium coatings
• Non-destructive magnetic and eddy-current measurement principles
• Handheld, portable design for on-site testing
• Fast readout for quick inspection workflow
• Compatible with both curved and flat surfaces

How to use

Place the gauge probe perpendicularly on the coated surface and allow the instrument to stabilise before reading the displayed thickness value. Select the appropriate substrate mode (ferrous or aluminium) if the device requires manual switching. For best results, take multiple measurements across the area of interest and record values to identify variations. Ensure the probe tip and the test surface are clean and free from loose debris prior to measurement.

Recommendations

Calibrate the gauge periodically according to the manufacturer's instructions using reference standards or foils to maintain accuracy. Avoid measuring over heavily rusted, excessively rough or loosely bonded coatings as these conditions can affect results. Store the instrument in a dry, stable environment and replace batteries promptly when low to ensure consistent performance.
