Every year or two I drag out my old testers for a clean-up.
Thought I'd share a few of them with you.
This is one of my first clamp meters. It still works fine.
This mega tester is over 20 years old and still going strong.
And this one is even older and still passed calibration earlier this year....
This is my RPM tester for motors. It nearly didn't get allowed on a site recently, the H&S brigade made me fill out a full 8 page risk assessment just for this tester.
