Simple
- Inexpensive, single-use dollies eliminate cleaning for re-use and can be kept as a permanent record
- 10, 14, 20 or 50 mm dollies maximize capability and measurement resolution across a wide range of bond strengths
Durable
- Environmentally sealed enclosure – weatherproof, dustproof and shockproof – meets or exceeds IP65
Accurate
- Self-aligning aluminum dolly enables accurate measurements on smooth or uneven surfaces
- Calibrated and certified to ± 1% accuracy using a NIST traceable load cell
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
