The Autool SDT205S is a professional leak detection unit, designed for quickly and accurately locating leaks in various vehicle systems. What makes this diagnostic tool unique is the built-in air pump and the dual test mode (air and smoke), which can be powered directly via a 12V battery. This allows you to work independently of an external compressed air source and switch directly between a pressure test and a smoke test for a complete diagnosis.
This smoke machine generates a constant and safe smoke flow to make even the smallest leaks visible. Thanks to the working pressure of less than 1.03 bar (15 psi), the unit is safe for all vehicle systems, including sensitive EVAP systems. With a smoke output of up to 6 liters per minute, the SDT205S quickly fills any system, significantly reducing diagnostic time. The adjustable flow meter gives you precise control over the process.
