What equipment is classified as Type I DFT measuring equipment?

The classification of Type I DFT (Dry Film Thickness) measuring equipment includes devices that rely on magnetic or eddy current principles to measure the thickness of coatings applied to metal substrates. Banana or manual gauges are a type of handheld device commonly used for this purpose. They typically feature a probe that can be placed against the coated surface to obtain a reading, providing a direct measurement of the dry film thickness of a paint or coating.

Given their widespread use and relatively straightforward operational principles, manual gauges are practical options for field measurements and are often employed in various coatings inspections, aligning with the standards set forth for Type I DFT equipment.
