PullTester 25

PullTester 25
Motorized testing device for destructive pull force tests up to 1,000 N (220 lbf). For various testing standards.

Schleuniger’s PullTester 25 is a dual-range, motorised, bench-top unit designed to measure pull-test forces of wire crimp connections as well ultrasonic metal welding connections on a wider range than single-range pull test devices. These measured values are indispensible parameters (IEC 352-2 standard) for quality control and assurance. This standard requires measurement at the maximum measured force (destructive test). This versatile machine has two measuring ranges, which are individually calibrated enabling use of its 500 N scale for small wires, while easily switching to its 1000 N scale for larger wres. This dual-range capability ensures the highest accuracy for the widest range of applications.

Hand actuated or pneumatic pull test devices can give inconsistent data depending on the operator or pull rate. The IEC standard specifies that a pulltester measures with a consistent pull rate. The Schleuniger PullTester 25 is equipped with a controlled speed motor, ensuring consistent pull rates throughout the measuring range which means repeatable and accurate data. Pull forces can be measured in pounds, New tons or kilo ponds. The standard 12-position terminal holder accommodates a wide variety of terminals to suit most applications. A variety of terminal holders, however, are available upon  request.


Out of a range of two devices the PullTester 25 is the base model. It's counterpart, Pulltester 26 has more features to accommodate more stringent test requirements. The machine will test pull forces up to 1000 New tons (220 lb.) and is specially suited for quality assurance in a production environment.
