Stress test an electrical connection to make sure it won't come apart. Often used to check the quality of electrical connections during manufacturing, these pull testers measure the force needed to pull terminals and other connectors off of wires and tubes. They work with many different wire diameters, including most insulation types—turn the wire end fixture until you find a slot that fits your wire. To help you automate tests, you can set these testers to automatically store or output data, and to zero out when a test sample breaks. For pass/fail testing, you can set high and low points—an alarm will sound if the sample falls out of the set range. A backlit LCD makes it easy to read measurements, even in low lighting.

These testers include software that lets you gather continuous data or focus in on a single data point. Export your measurements to Excel using the included USB cable. You can also send data to your computer or PLC via RS-232, Digimatic code, or analog outputs. These testers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.
