Ems technologies make pull tester 26 of dual range, motorised, bench-top unit designed to measure pull test forces of wire crimp joints as well as ultrasonic metal welding connections on a wider range than single range pull test divices. Iec standard specifies that a pull tester measures with a consistent pull rate. These pull tester 26 is outfitted with a controlled speed motor, ensuring consistent pull rate throughout the measuring range thus giving repeatable and exact data.
