Automatic and manual Pull-off Adhesion Testers

PosiTest AT - Automatic Pull-off Adhesion Tester

Measures adhesion of coatings to metal, wood, concrete and other rigid substrates

Measuring range: 0.7-24 MPa (based on 20 mm dolly) or 0 - 3.8 MPa (based on 50 mm dolly)
Electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure. Greatly reduces user effort and the risk of influencing the pulling process
Impact and scratch resistant color touch screen with keypad for operation with or without gloves
Built-in rechargeable battery performs over 200 tests per charge. Continue testing with AC power while the battery recharges
Environmentally sealed enclosure—weatherproof, dustproof and shockproof—meets or exceeds IP65
Rubberized, shock absorbing grips provide a stable, skid-resistant footing
Self-aligning aluminum dolly enables accurate measurements on smooth or uneven surfaces
10, 14, 20 or 50 mm dollies maximize capability and measurement resolution across a wide range of bond strengths
Maximum pull-off pressure by dolly size...:

10 mm: 14000 psi (96 MPa)

14 mm: 7000 psi (50 MPa)

20 mm: 3500 psi (24 MPa)
50 mm: 560 psi (3.8 MPa)

User selectable measurement units: psi (pounds per square inch), MPa (Megapascal), Nmm² (Newtons per millimeter square) or Newton (force)
User adjustable pull rate, pull limit and hold time
Rotating display for horizontal and vertical use
Calibrated and certified to ± 1% accuracy using a NIST traceable load cell

WiFi technology wirelessly communicates with PosiSoft.net, downloads software updates and allows access to stored measurement data using standard web browsers
PosiSoft USB Drive—stored readings and graphs can be accessed via USB using universal PC/Mac web browsers or file explorers.
No software required
Compatible with PosiSoft Desktop, PosiSoft.net and PosiTector App (Apple iOS and Android) software solutions

Touch Screen Display

Use the touch screen to interact with menu options.

Swipe horizontally to navigate between views or vertically to move between batch readings.

Alternatively, the keypad can be used for navigation and selection.

PosiTest AT - Manual

Hydraulic Pull-off Adhesion Tester

The PosiTest AT - Manual uses manually generated hydraulic pressure to measure the force required to detach a specified test area of a coating from the substrate.

Delivery including calibration certificate

Options:

Extension set to accommodate 50 mm test bodies (dolly) for e.g. concrete, drill bit for thick coatings, Pelicase case upgrade (robust & waterproof, replaces standard case)
