  5-8840-2608-0 EVAP Pressure/Purge Diagnostic Station is a multipurpose tool which is used to perform several

diagnostic procedures for enhanced emission testing. The station will accommodate a nitrogen gas filled cylinder

which is used to pressurize the vehicle EVAP system for a leakdown test and leak location test when a vehicle is

repaired for leakage in the enhanced evaporative emission control system. It also has two additional gauges

inches of mercury and inches of water) which are used to measure both source vacuum and EVAP canister

purge vacuum to verify correct operation and vapor flow within the canister purge circuit.

  5-8840-2608-0 Ultrasonic Leak Detector is a microprocessor-based device used to detect leaks in the enhanced

evaporative emission control system. the evaporative system is pressurized to 30 inches of water using the

5-8840-2608-0 EVAP Pressure/Purge Diagnostic System. Small leaks in the EVAP system will emit sound at a

high frequency undetectable by a human ear but detectable with the 5-8840-2608-0. The technician traces along

the evaporative system and can pinpoint leaks due to corroded lines, cracked hoses, or a damaged EVAP

component. The detector includes a high quality set of headphones to block out surrounding shop noise and the

LED sensitivity meter allows a visual reference for locating leaks in conjunction with the audio output heard

through the headphones. Powered by (1) nine volt battery.
