Key Features

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
Pressure system is calibrated and certified to ± 1% accuracy using a NIST traceable load cell
Software Updates via web keep your instrument current

Memory and Reporting Features

Internal memory stores maximum pull-off pressure, rate of pull, test duration and dolly size for 100,000 pulls in up to 1,000 batches
Record the results as pass/fail and the nature of fracture – cohesive, adhesive and glue failures
Wirelessly connect to your smart device using our free PosiTector App (Apple iOS and Android)
WiFi technology wirelessly communicates with PosiSoft.net, downloads software updates and allows access to stored measurement data using standard web browsers (see WiFi Features for full details)
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
