Mandatory tool for many OEMs. Built to major automakers' specifications. OEM Approved technology will not damage vehicle components and will not void factory warranties. 

Patented UltraTraceUV solution
allows you to see the leak with smoke and UV-activated fluorescent dye. Refillable smoke chamber; hundreds of tests between refills - costs only pennies to operate.

Nitrogen-based technology; safer for EVAP testing because it does not introduce oxygenated air in vehicle's fuel tank. Uses shop air for all general purpose leak testing.
Dual phase function quickly verifies .040" or .020" leak in EVAP system.  Has all general-purpose leak testing capabilities in addition to EVAP testing features. 
"Future-ready" in the event leak standards change.
Includes complete line of accessories (as shown).

SPX/OTC Diagnostic Smoke™ Vapor-Producing Machines - Feature Comparison

6525 6521
1 Contains patented STAR Diagnostic Smoke™ technology inside; developed in collaboration with Ford Motor Co., G.M. & Chrysler (Big-3 U.S. automakers) and approved by virtually all major OEMs* b b
2 Patented UltraTraceUV dye solution and our basic non-dye solution are the ONLY solutions tested and approved by the Big-3 (and others) to be safe to use without harming activated charcoal canister, ORVR valve, purge valves, catalytic converters, O2 sensors, seals or gaskets and determined not to void vehicle factory warranty* b b
3 Designed with an electronic Safety Valve that automatically shuts off air flow into the vehicle's EVAP system every time the machine turns off. This stops gasoline fumes from possibly continually exiting the EVAP system and filling your work bay* b b
4 Meets spec if OEM requires nitrogen to produce the smoke when testing the EVAP system* b b
5 Fully automatic auto-EVAP pressure setting that is NOT adjustable, preventing any accidental over-pressurizing of the EVAP system* b b
6 Unit's system test pressure can be calibrated in the field, assuring test accuracy for many years to come* b b
7 Same full-feature design as chosen by many OEMs b  
8 Internal orifice calibration for 0.020" = 2000 vehicles and newer b  
9 Internal orifice calibration for 0.040" = 1999 vehicles and older b  
10 Built-in "Future" up-gradable leak standard b  
11 OEM test modes: Phase-one & Phase-two b
