Achieve Absolute Accuracy with Automatic Adhesion Testing

Manual hydraulic pumps require inspectors to crank a handle smoothly to measure coating bond strength. However, uneven manual pumping creates pressure spikes that snap the paint glue prematurely. An automatic pull off adhesion tester solves this issue by using an internal motor to apply perfectly smooth, continuous hydraulic force.

Why Quality Engineers Automate Pull-Off Testing

Automated testers deliver the highly repeatable pull rates that modern industrial standards demand. They remove human physical variance entirely, allowing your inspection team to gather defensible data that passes strict client audits.

Key performance benefits include:

• User-Selectable Pull Rates: Program exact force increments, such as 1 MPa per second, to satisfy different international testing rules.

• Rugged Waterproof Design: Sealed metal enclosures protect internal electronics from harsh offshore salt spray and dust.

• Rechargeable Battery Systems: Powerful internal batteries pull dozens of heavy-duty dollies on a single overnight charge.

• Instant On-Screen Graphs: View live pressure charts right on the digital screen to see the exact moment a coating fractures.

Tester Dolly Size Configuration

Select the ideal dolly diameter to match the expected tensile strength of your specific substrate material.

Dolly Diameter	Maximum Pull Force	Pressure Range	Primary Substrate Use
20 mm Standard	3000 lbs	0.7 to 20 MPa	Protective Paint on Steel
50 mm Large	750 lbs	0.2 to 3.5 MPa	Concrete, Wood, and Plastics

Streamline Your Paint Inspection Workflow

Operating this electronic system requires very little effort. Simply glue your aluminum dolly to the coated surface, attach the quick-coupling actuator, and press the start button. The machine pulls smoothly, saves the peak break value, and records the test date automatically.

Pro Tip: Use the built-in Bluetooth feature to transmit your pull-off reports directly to your smartphone before leaving the job site.
