💨Quick Leak Diagnosis
The FOXWELL SD203 automotive smoke tester is designed for all 12V vehicles, including cars, minivans, and light-duty trucks. It delivers thorough leak detection across critical systems such as EVAP, Emission, EGR, vacuum, engine, intake, exhaust, fuel tank, turbo, and more—ensuring your vehicle maintains peak performance and safety.
👍Efficiently Save Time & Safety
With a 10-minute work cycle—double the industry standard—the SD203 car smoke detector extends your testing capabilities. Its unique variable frequency technology ensures continuous operation, even under high temperatures. The patented smoke generation system reduces power consumption by over 30% and temperature rise by more than 40%, using just 3ml of smoke oil per 10 minutes, protecting your car battery and maintaining safe temperatures during tests.
💥Dual Modes for Precision & Efficiency
Quickly identify potential leaks in Air Mode, which allows for fast detection of smoke-sensitive components. For more precise pinpointing, switch to Smoke Mode to reveal hidden leaks with visible smoke. This dual-mode feature improves testing efficiency and reduces smoke oil consumption.
☄️Integrated Air Compressor
The SD203 eliminates the need for expensive external compressors with its built-in high-performance motor. It operates within a pressure range of 0.8 to 1.2 bar and delivers a smoke output of 16L/min, enabling you to perform tests anywhere. Save on setup costs while enjoying a reliable, portable solution.
📈Real-Time Pressure & Flow Adjustments
The built-in pressure gauge and flow meter allow real-time monitoring of leaks, ensuring even the smallest issues are detected accurately. Adjust the smoke output easily with the precision knob to tailor testing conditions for maximum efficiency.
✨Perfect Testing Solutions
Test a wide range of vehicles, from cars and motorcycles to trucks, ATVs, boats, RVs, and more. The smoke tester comes with practical accessories, including intake adapter cones, air drum rubber, and 23 full-size cap plugs, ensuring a perfect seal for every test.
🌈How to do leakage test？
1. Turn OFF the ignition of the vehicle.
LEAK TEST OF VEHICLE SYSTEMS REQUIRES THE ENGINE TO BE OFF
2. Dismantle the air filter and the throttle connections.
3. Clean the inner wall of the intake opening to avoid sharp objects and put the Universal Intake
Adapter into the opening
4. Connect the Power Cord to 12V vehicle battery.
5. Now the Power LED would be ON, if else check the power supply.
6. Introduce the smoke nozzle into the system via the Adapter Cone
7. Press Air Control Switch, wait for 30 seconds until the system is pressurized, and check the
Pressure Gauge & Flow Meter reading for leak status, if the unit is equipped with Pressure Gauge & Flow Meter
8. Press Smoke Control Switch, .unplug and Plug back the smoke nozzle back into the Cone Adapter when there’s obvious smoke coming out of the smoke nozzle
9. The system will be ready for leak check in 2 minutes. Use a bright light torch or working lamp to assist
10. After test, press Smoke Control Switch again to stop the unit from generating smoke and
press Air Control Switch to stop generating pressurized air
11. Collect the Smoke Hose and the Power Cord with the Velcro Straps for storage. Hang the unit or make it stand in UPRIGHT position only. Do NOT lay it down.
