TAKK's Model 9195 Neon Bar Checker is a handy tool for checking the effectiveness of
static eliminator bars.
This compact, pen-sized device lights up a neon indicator to show that each bar emitter is functioning properly. It helps you spot any issues with your static eliminator bars, like problems with transformers, shorts in the system, or if they just need a good cleaning. You can use this bar tester with both shockless and "hot" static control equipment.
