Test equipment

Test equipment for gas discharge tubes, Varistors etc. Exact direct measure of the clamp voltage. Low test current which doesn't "ages" the component. This tester is a portable field version which also can be used for testing transistors, zener diodes etc. up to 1000V. It's guaranteed lower limit is 50V but often can tests be made down to  10V. The batteries is enough for 25000 tests!
