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 “Chassis Ground”. Audible alarms alert technicians to found electrical faults.
Available in three versions, the Pro-Check is the ultimate commercial trailer light tester and electrical diagnostics tool on the market today.
The Pro-Check 720 includes a 7-way “round-pin” connector, remote control, and provides rapid light and electrical testing of commercial trailers. The Pro-Check 720 is available in either 12-volt DC or 110-volt AC.
Pro-Check, trailer light and electrical testers operate on DC power. This makes them suitable for use in shop and mobile environments. A battery or regulated DC power supply is required. Unregulated power supplies such as power inverter or battery charger should not be used as they may cause damage to the trailer being tested or the tester itself.
The AC version of the Pro-Check 720 has a built in regulated DC power supply so it can be plugged directly into a 110 volt, 3-prong power supply.
The Pro-Check 725 includes a 7-way “flat-pin” connector and remote control. The Pro-Check 725 is best suited for testing medium and light-duty trailers (utility trailers). Powered by a 12-volt DC power source, the Pro-Check 725 has an on-board battery voltage display and activates trailer brake lights for as long as the trailer’s brake lights are activated with the trailer light tester diagnostics controls.
