   Precision Pull-off Adhesion Test Equipment

PAT adhesion tester
AT101/40kN 

1	Tensile adhesion testing of thermal sprayed coatings using Ø25mm (1 inch) test cylinders either on test panels or two cylinders glued together (ASTM-C633) ASTM-jig is an optional accessory.
2	Accurate measurement of tensile strength of concrete products with a choice of either the Ø50mm or Ø70mm test cylinder sizes.  This model is also used for testing cement based tile adhesives using the 50x50mm square test element.

In addition, this adhesion testing machine is used for pure tensile testing of various materials where strain measurements are not required.  The test equipment complies with ISO 4624, ASTM D 4541, EN 1542 and ASTM C633.

Different test ranges are achieved by using different test element sizes (see table below).   

Description
	Portable and simple to use.
	Produces comparable test results both in the laboratory and on site.
	Precision gauge with both MPa (N/mm2) and p.s.i. reading.
	Simple layout of control panel.
	Rate of tensile force increase is infinitely variable between zero MPa/sec (standstill) up to maximum rate (the rate depends on the size test element used).
	110/230V mains power.  Battery power is an optional extra.
	All AT101 adhesion testing machine models can have the data logging module built in when new or retro-fitted into existing units.
	Testing of coatings on any shaped substrates, e.g. inside and outside pipe surfaces.
	Supplied in solid aluminium case.
