Innovative Products of America's Super MUTT (Mobile Universal Trailer Tester) is the company's latest solution to time consuming and often inaccurate testing of trailer circuits and air braking system. The tester is an advanced diagnostic tool utilizing two Group 31 batteries that can quickly test and identify all trailer lighting functions (cross circuits, short circuits, open circuits, etc.) and air brakes. The compact size and robust design with laser-cut metal makes it easily transportable to on-road sites. It comes with rubber tires, a remote control for air brakes and an inlet for full-time emergency air supply. The company says the SuperMUTT can save a minimum of 20 to 25 minutes per trailer inspection, and 45 minutes to several hours on problem trailers, providing an average return on investment in 26 days.
