Pro-check

Complete Electrical Diagnosis With The Touch Of A Button

Pro-Check trailer light testers with advanced electrical diagnostics are rugged, lightweight, and economical. They independently test each electrical circuit on a trailer to ensure proper connectivity. The Pro-Check identifies each specific type of electrical wiring fault. Lite-Check’s patented active diagnostic system takes the guesswork out of identifying trailer light and electrical problems. The Pro-Check commercial trailer light tester with electrical circuit diagnostics, not only identifies faults, but the specific circuit the fault is on. Faults are identified as “Open Circuit”, “Open Ground”, “Short” (w/all circuits identified), or “Short to Ground”. Audible alarms alert technicians to found electrical faults.

​

The Pro-Check is the ultimate commercial trailer light tester and electrical diagnostics tool on the market which provide rapid light and electrical testing of commercial trailers.
There are 4 versions of the Pro-Check.
