Destructive pull testers are used to test for changes in weld, wire and crimp quality. Today's pull testers offer more features for the money, better data consistency and fewer errors. Data collection is more accurate, more efficient and more economical than older manual pull testers, which can be cumbersome and inconsistent. ISO and QS standards require that a test be accurate and repeatable from one operator to the next.

Todays motorized constant adjustable speed pull testers ensure consistent and adjustable pull rates. Military, SAE and American National Standards Institute specifications require a pulling speed of 1 inch per minute, and many European customers prefer rates to 4 inches per minute.

Our pull testers feature high accuracy electronics and multiple load sensors so the range of the machine is wider in terms of the sample being pulled. A pull tester with a 1000 pound load cell offers ±11 gram error at 5 pound readings and if that is not good enough on the lower range, an affordable smaller cell extends that to gram level accuracies. Our systems eliminate the need to purchase multiple pull testers to cover your entire range of wires.

Some models automatically record data into memory with a time and date stamp and that data can be downloaded to a PC. The time and date stamp associated with each test reading also assures the customer that the values were taken at the right times and that the data correlates with the job that was actually run.

Nondestructive pull tests feature a load control mode where a harness, for instance, is loaded to a adjustable level for a specified period and the machine returns home. These tests ensure product compliance to specifications requiring each sample to be checked prior to usage.
