Connect the adhesion tester’s actuator to the PosiTest AT Calibrator's loading fixture.
Apply pressure using the adhesion tester’s normal operating procedure.
Compare values from the adhesion tester and the PosiTest AT Calibrator.
The PosiTest AT Calibrator is used to verify the accuracy and operation of all PosiTest Adhesion Testers and is an important component in fulfilling both ISO and in-house quality control requirements. Contracts often specify that adhesion tests be performed with instruments that have measurement accuracy traceable to a National Metrology Institute such as NIST.
Yes. The high precision load cell measures in both MPa and psi scales and is available with or without a PosiTector gage body. A PosiTector gage body is required for use. The Calibrator is fitted with a permanent steel 20 mm loading fixture (dolly) and is compatible with all PosiTest Pull-Off Adhesion Testers—a 20 mm standoff is required for 50 mm models (not included). A conversion factor is used to verify other sizes.
No, not without user modifications to the loading fixture (dolly) and test points.
We recommend customers begin their calibration intervals based on the recalibration date printed on the Certificate of Calibration for the load cell.
