DeFelsko ATM20 | PosiTest AT-M Manual Adhesion Tester | 20 mm Kit
The DeFelsko ATM20 is the PosiTest AT-M manual pull-off adhesion tester supplied with the 20 mm Kit for higher bond strength coatings on metal. A manual hydraulic pump applies smooth pressure with a single stroke, while a pull rate indicator helps the operator hold the correct rate. It is widely used by coating inspectors on steel structures and fabricated parts.
- Range 0.7–20 MPa (100–3000 psi)
- Includes 20 aluminium Ø20 mm self-aligning dollies and a 20 mm hole saw
- Stores maximum pull-off pressure, pull rate, duration and dolly size for 200 pulls
- Colour display; field replaceable AAA batteries
- IP65 sealed housing
- Conforms to ASTM D4541, ISO 4624 and other standards
