Memory & Reports
- 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
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.
APP Features
- Add images and notes using the camera or keyboard
- Create customized, professional PDF reports
- Share, backup, synchronize and report measurement data
- Auto-pairing Bluetooth (BLE) connection
- See the Help File to learn about how it works
Recording the Nature of the Fracture
Upon completion of a pull-off test, the dolly and coated surface should be examined. In addition to pull-off force, many National and International standards such as ASTM D4541 and ISO 4624 require the nature of the fracture to be recorded.
- Cohesive fracture: fracture occurs within a coating layer (same coating on dolly face and coated surface).
- Adhesive fracture: fracture occurs at the interface between layers (coating on dolly face differs from surface).
- Glue failure: visible separation of the glue from itself, the coating or dolly (no coating visible on the dolly face).
