How to Measure Adhesion 8:50
Measuring Coating Adhesion to Metals, Concrete, and more with the PosiTest AT from DeFelsko- the Measure of Quality.
The PosiTest AT-M Manual Adhesion Tester by DeFelsko Measures the force required to pull a specified test diameter of coating away from its substrate using hydraulic pressure.
- Manual hydraulic pump designed to apply smooth and continuous pressure with a single stroke
- Pull Rate Indicator to manually monitor and adjust the rate of pull
- Internal memory stores maximum pull-off pressure, rate of pull, test duration and dolly size for up to 200 pulls
- Compatible with PosiSoft Desktop for viewing, printing and storing measurement data
