Overview
Defelsko PosiTest ® AT Verifier is a validation kit for verifying the accuracy of adhesion testers. Ideal for checking the accuracy and operation of adhesion testers, it is an essential part of meeting ISO and internal quality control requirements, allowing users to demonstrate the accuracy of PosiTest adhesion testers.
Features
1. Equipped with High Accuracy Weighing Sensor and Handheld Smart Sensor Indicator.
2. With peak hold and real-time reading display functions.
3. The gluing foil strain gauge adopts sealing design to adapt to the industrial environment.
4. Can be used in all PosiTest pull-off adhesion testers at any time.
5. Suitable for field or laboratory use, portable and without external power supply.
6. Equipped with a permanent steel 20mm loading fixture (trolley), and provides a conversion factor for verifying Miscellaneous dimensions.
7. Both the Load Sensor and the Smart Sensor Indicator contain a calibrated certificate that shows traceability to NIST.
8. Sample with sample accuracy and measurement uncertainty worksheet.
Principle
The validation kit works via a High Accuracy Weighing Sensor (Load Sensor) and Smart Sensor Indicator. The user connects the actuator of the adhesion tester to be calibrated to the loading fixture of the validation kit, and then applies the pulling force according to the normal operating procedure. The validation kit's Sensor accurately measures and displays the applied force value, and the user verifies the accuracy of the tester by comparing the readings of the adhesion tester with those of the validation device.
Applications
Adhesion tester accuracy calibration, quality control
Steps
1. Connect the pull-out actuator of the adhesion tester to the loading fixture of the PosiTest AT Verifier.
2. Apply pressure using the normal operating procedure of the adhesion tester.
3. Compare the values of the adhesion tester and verification equipment.
Notice
• Please ensure that the equipment is in good condition and firmly connected before use.
• Please follow the normal adhesion tester operating procedures when operating.
• When comparing readings, refer to the calibrated certificate and conversion factor provided by the device.
Equipment is suitable for field or laboratory use, but care should be taken to keep it properly in an industrial environment and use its sealing properties to prevent damage.
When verifying a Miscellaneous size tester, be sure to use the correct conversion factor.
