Byko-test 4200/4500

Byko-test 4200/4500 is a BYK-Gardner dry film thickness gage used to measure the thickness of dry coating layers on metal substrates. This instrument helps users perform fast, practical, and non-destructive coating quality control, making it suitable for production inspection, field inspection, laboratory testing, and coating application process validation.

In coating applications, dry film thickness is critical because it directly affects protection performance, corrosion resistance, surface appearance, and material consumption. Byko-test 4200 is designed for measurement on ferrous substrates such as steel or iron, while byko-test 4500 supports measurement on Fe and NFe substrates such as steel, aluminum, copper, brass, zinc, and stainless steel. With automatic substrate recognition, users can measure different materials without complicated cable changes or recalibration.

Byko-test 4200/4500 features a compact pocket-size design and is comfortable for one-handed operation. The instrument includes a strong wear-resistant ruby probe tip, V-groove probe for positioning on cylindrical parts, large LCD display, acoustic signal for measurement confirmation, and selectable microns or mils units. This product is suitable for protective coatings, industrial coatings, automotive coatings, metal finishing, powder coatings, and applications requiring repeatable dry film thickness measurement.
