Bosch’s HPT 500 High-Pressure Diagnostic Leak Tester provides a solution for heavy-duty vehicle diagnosis and repair by producing a larger volume of smoke necessary for larger systems. The machine delivers leak detection smoke at up to 30 psi to produce higher pressures and simulate truck boost to test and find leaks in exhaust aftertreatment systems. Designed to test an entire system in 15 minutes and with dual operating modes, technicians can alternate quickly between smoke-only and air-only cycles to confirm repairs. The machine also features a flow control valve, remote shutoff, a flow rate gauge and system pressure and test pressure gauges. The HPT 500 comes with a bottle of vapor-producing fluid, a remote control key fob, a 100-240-volt AC plug and a hex key. The housing is constructed of steel and billet aluminum for added durability and extended service life.
