SML310 at a glance
Overview
The AUTOOL SML310 smoke tester for vacuum leaks is a professional tool for quickly and accurately identifying leaks in vehicle systems. Its advanced intelligent pressure control and temperature protection ensure a steady, powerful smoke output, making leak detection more efficient and reliable. By providing clear visual indication of any leakage, it helps users save time, improve diagnostic accuracy, and determine whether pipeline faults are causing vehicle issues.
AUTOOL smoke leak detector adopts forced combustion and smoke generation in a low-oxygen environment. The heating wire is energized through conductive columns, rapidly heating to above 300°C, causing the mineral oil to reach its ignition point and enter a combustion state. Due to the small intake flow, there is insufficient oxygen to maintain complete combustion, so combustion primarily occurs on the surface of the heating wire. The mineral oil residues, under high-temperature heating, cannot fully combust around the heating wire, resulting in the production of a large amount of smoke.
Two Testing Modes: Air Mode / Smoke Mode.
Rapid Pipeline Leak Detection: Supports testing the leakage of various pipeline systems, including automotive intake systems, EVAP systems, exhaust systems, and engines.
Overheat Protection: Prevents dry burning with an alarm indicator light. Automatically stops operation if the temperature exceeds 75°C.
Power Source: Operates on DC12V power with built-in air pump to suit different working conditions.
Large Smoke Output Volume: Generates smoke within 5 seconds; working pressure can exceed 1 bar, with a smoke flow rate ≤6L/min. Can produce a large amount of smoke within 30 seconds to locate leaks.
Oil Drain Valve: Allows for recovery of residual smoke oil after use, promoting environmental friendliness and enabling reuse of test oil.
Visual Pressure Gauge: Observes the pressure state of the pipeline system through the gauge, helping to identify potential leaks.
Wide Application Range: Suitable for all types of vehicles, including passenger cars, motorcycles, off-road vehicles, snowmobiles, and speedboats
Three-year Warranty: For damages caused by non-human factors, AUTOOL promises to provide free replacement parts within three years. If you have any requests, please feel free to contact us, and we will respond promptly within 24 hours.
1. Inject 10 milliliters of baby oil into the detector for the first time. Open the hood and hang the detector on the hood.
2. Disconnect the pipeline that needs to be connected to the detector.
3. Connect the detector to a DC12V battery, turn on the power switch, and the detector will begin to operate.
4. After approximately 30 seconds, the pipeline will be filled with smoke. Check for leak points. Use a headlamp if necessary.
