Paint thickness gauge Prodig-tech GL-8 — universal coating thickness tester (Prodig-tech)

Prodig-tech GL-8 is a handheld, universal paint thickness gauge for quick, non-destructive measurement of coating thickness on a variety of substrates. The tester is designed to deliver fast and repeatable readings of paint and lacquer layers, helping users evaluate repainted areas, validate coating uniformity and perform pre-purchase vehicle inspections. Portable and straightforward to operate, the GL-8 is suited for automotive, industrial and inspection applications where reliable thickness data is required in the field.

Advantages

The device offers universal measurement capability for both ferrous and non-ferrous substrates, enabling versatile use across different materials. Its compact handheld form factor and intuitive controls make it convenient for field inspections and workshop use. The GL-8 provides immediate digital readouts, facilitating rapid decision-making without damaging the coating. Robust construction ensures durability during routine on-site measurements.

Suitable for

• Pre-purchase vehicle inspections to detect repainted or repaired panels
• Automotive bodyshop quality control and paint process checks
• Industrial equipment and metal component coating verification
• Routine maintenance inspections where coating thickness monitoring is required

Key specifications

• Measurement principle: non-destructive magnetic and eddy-current methods for different substrates
• Measurement range: suitable for thin to common automotive and industrial paint layers
• Display: digital readout for direct thickness values
• Portability: compact handheld design for field and workshop use
• Repeatability: provides stable, repeatable readings for inspection tasks

How to use

Place the probe flat on the coated surface and start a measurement according to the instrument’s operating procedure. For best results, ensure the surface is clean, dry and free of loose debris. Take multiple readings across the area of interest to identify variations in coating thickness and to verify consistency. Interpret the displayed values to assess whether layers are within expected ranges for the application.

Usage recommendations

Calibrate the instrument as recommended by the manufacturer before critical measurements and verify operation on known reference samples. Avoid measuring over highly curved or irregular areas without using appropriate fixturing, and store the unit in a dry, stable environment to maintain accuracy.
