ASTM D5725

DAT 1121 Dynamic Contact Angle Tester – PG1050 – or – DAT 1122 Dynamic Contact Angle Tester – PG1051

The DAT measures the contact angle (dynamic and static), surface tension, penetration, surface energy and spreading. The instrument uses a sophisticated camera to capture the fall/ shape of the drop, the shape on the sample and eventually the penetration. The pump and the camera work closely together. This is critical to have the correct amount of liquid and have each test start at the same time.
