ANCEL S300 EVAP Smoke Leak Detector Diagnostic Tool

Quickly Pinpoint Hard-to-Find Vehicle Leaks

The ANCEL S300 Car Smoke Leak Detector is a professional diagnostic tool designed to locate leaks in EVAP systems and other closed automotive circuits. Powered directly from a 12V vehicle battery, it features a built-in air pump, adjustable flow meter, and integrated pressure gauge, allowing you to introduce controlled air or smoke into the system and monitor pressure changes in real time.

With an output pressure of 0.8-1 PSI and a flow rate up to 6 L/min, the S300 is suitable for intake, exhaust, crankcase, turbo, fuel tank, and general hose and pipe testing on cars, motorcycles, ATVs, light trucks, and more. Overheat protection automatically shuts the unit down above 75°C, while anti-frost protection allows reliable operation down to -20°C. Compact and portable, it delivers visible smoke in as little as 10 seconds for fast, accurate leak location.

Why It's a Smart Choice

• Dual Air & Smoke Modes - Use air mode first to confirm if a system is leaking, then switch to smoke mode to visually locate the exact leak point.
• Clear Pressure & Flow Diagnostics - The built-in pressure gauge and adjustable flow meter help distinguish between no leak, small leak, and major leak conditions.
• Wide System & Vehicle Compatibility - Supports EVAP, intake, exhaust, crankcase, turbo, fuel tank, and sealing tests across most vehicle makes and models.
