The KTA-Tator certified stainless steel wet film thickness gauge or wft gauge replaces 4 gauges needed to perform the same range. The patent-pending dual-head design allows 0-60 mils of coating to be measured and converted to microns (0-1524) by just flipping the gauge over. 5 measurement points per head allow more precision than competing equipment in the same form factor. Each wet film thickness gauge comes with a unique ID number and certificate of conformance at no additional cost. Also included is a carrying pouch. Each gauge conforms to ASTM D4414.
The usage of these WFT gauges is straightforward. Each one of the faces is going to have a different range so initially select one that fits the amount of coating applied, as this will reduce the time it takes to get your reading.
Immediately after the coating has been applied insert the measuring face that you selected into the wet coating. When inserting the wet film gauge make sure that the two end teeth are pushed all the way into the previous layer or the substrate (if you are on your first layer) at a 90° angle.
You are then going to want to remove the wet mil gauge from the coating. After removing look at the numbered notches, on the side that you inserted into the coating. The two stabilization teeth should have paint on them. If all the numbered notches have paint on the ends you are going to want to move to a higher head. If none of the numbered notches have paint on them, you will want to move to a lower head. Your wet film thickness will be the last notch of the wet film gauge that has paint on it.
