PosiTest® – Magnetic Coating Thickness Gages

Description

PosiTest® – Magnetic Coating Thickness Gages for Non-Magnetic Coatings on Steel

The PosiTest® Magnetic Coating Thickness Gages (commonly known as banana gauges) provide accurate, non-destructive measurement of non-magnetic coatings such as paint, enamel, galvanizing, plating, and more—on steel substrates.
Built for tough industrial environments, these gauges deliver precise, repeatable readings for coating inspection and quality control.
