Air brake leaks can quickly turn into big problems and add to operating expenses. For instance, when air break leaks occur, a vehicle loses adequate continuous air pressure. This causes the brakes to set and lock if the pressure gets too low. A truck in need of repair can cost a company upwards of $900 to $3,000 per day due to downtime and unproductivity. 

Tracer Products introduced the TP-9367L Marksman II Ultrasonic Diagnostics Tool.

The ultrasonic diagnostic tool can help make finding air brake leaks much less challenging, according to the manufacturer. The Marksman II operates on the principle that pressurized leaks produce friction and ultrasonic sound at the leak site. The Marksman II converts and amplifies inaudible ultrasonic sound into an audible “natural” sound the ear can easily pick up. 

Key features include: 

  • Pinpoints air brake leaks, gear and bearing wear in wheel hubs, transmissions, transfer cases, differentials, compressed air, vacuum, electric motors, and other pressurized leaks quickly.

  • Laser pointer to help pinpoint the source of pressurized leaks.

  • Checks for electrical discharge associated with insulation breakdown, carbon tracking, and arcing.

  • Unique ultrasonic emitter helps locate faulty seals, gaskets, and weather stripping in passenger cabs, trailers, and other non-pressurized enclosures.
