Introduction to Leak Detection
Leak detection is a crucial process in the automotive industry, as it helps identify and diagnose issues with a vehicle’s critical systems. A smoke leak detector is an essential tool for this purpose, as it uses a smoke machine to visualize leaks in the vehicle’s systems.
The FOXWELL SD203 Automotive Smoke Machine is a high-quality smoke leak detector designed to detect leaks in all 12V vehicles, including cars, minivans, and light-duty trucks. By introducing smoke into the system, technicians can pinpoint leaks quickly and accurately, ensuring that even the smallest issues are identified and addressed.

What is a Smoke Machine and How Does it Work?
Like the FOXWELL Smoke Machine, a smoke machine is a diagnostic tool designed to detect leaks in various automotive systems, including EVAP, fuel, and turbo systems. It works by generating a dense, non-toxic smoke that is introduced into the system you’re testing. This smoke travels through hoses, valves, and other components, emerging from leaks to reveal faulty areas.
The FOXWELL Smoke Machine includes both smoke and air modes for versatile leak detection. Smoke mode detects leaks using visible smoke, while air mode uses airflow sounds for quick leak detection. The FOXWELL Smoke Machine enhances this functionality by incorporating dual testing modes (low-pressure EVAP mode and high-pressure turbo mode), a built-in air pump, and a real-time pressure graph display on a 4-inch LCD screen.
