Utilizing the most advanced patented technologies, this VACUTEC^® 625-522B is the most comprehensive, yet simple to operate, Leak Detection System available today. It is the only smoke machine on the market approved by Mercedes-Benz USA LLC. 

This Tester always delivers the special smoke vapor using clean dry nitrogen.  Simply connect the VACUTEC^® 625-522B to compressed air (shop air) and the machine automatically converts the air to high-purity nitrogen, never running out of nitrogen.  The tester's special Diagnostic Smoke^® vapor is always delivered to the vehicle in a clean and safe inert medium. Its high nitrogen purity is guaranteed due to its computer-controlled nitrogen-purity monitor.

 A quick pass/fail test quantifies the size of a leak. Finding the leaks is simple. Introduce the special non-toxic Diagnostic Smoke^® vapor into the system to be tested, then simply look for the exiting smoke or the fluorescent dye deposited at the exact location of the leak(s). Also finds leaks in induction systems, throttle bodies, under-dash vacuum systems, exhaust and EGR systems, unfiltered and unmetered air systems, wind and water leaks and much more.
