Each tester is identified with a model and serial number stamped on the frame and should be mentioned in all correspondence relative to repair or when ordering parts. Penetrators should be examined periodically for wear and replaced with new ones. 

Please note the following for replacement parts:

Penetrators and Load Springs differ with each model tester.
All of the other parts are common to all three testers.
