Automotive Smoke Tester for EVAP System 12V- AUTOOL SDT103

AUTOOL SDT103Product OverviewThe AUTOOL SDT103 smoke leak detector is an EVAP-focused automotive smoke tester for low-pressure pipe leak checks. It uses an external air source, DC12V vehicle battery power, 10-15ml liquid paraffin or baby oil, and a visual airflow meter to help technicians locate small leaks in EVAP, intake, exhaust, fuel tank, pipe fitting, and vehicle sealing systems more efficiently.External Air Source DC12V Battery EVAP 3.2kPa 10-15ml Test Oil3.2kPaEVAP Output Pressure>10L/minRated Output Flow48WRated Power3 YearsWarranty Support Click to enlargeBefore You Order And UseBefore You Order And UseBefore ordering or using SDT103, confirm the external air source requirement, DC12V power supply, testing oil rule, airflow regulator, operating time limit, and hot-surface warning.External Air Source RequiredSDT103 does not have a built-in air pump. It must be connected to an external air source or shop air compressor before smoke testing.DC12V Battery RequiredConnect the SDT103 automotive smoke tester to a DC12V vehicle battery. Do not use it without the proper 12V power supply.Open The Airflow RegulatorBefore use, gently turn the airflow regulator valve to open airflow. The flow meter helps observe the current airflow volume during testing.Testing Oil Not IncludedTesting liquid is not included due to logistics restrictions. Buy liquid paraffin or baby oil locally for use as testing oil.Fill 10-15ml OnlyFor first use, fill 10-15ml testing oil. Do not exceed this range, and do not add more than 15ml each time.Refill Only When Smoke Gets ThinAdd fresh oil only when smoke becomes thin. Before adding fresh oil, pour out the remaining oil and replace detector oil regularly.8-Minute Continuous Use LimitDo not run the detector continuously for more than 8 minutes. Allow interval rest between tests to protect the unit.75°C ProtectionIf the device exceeds the working limit, such as over 75°C, the intelligent protection system turns off the power. Operate it again after it cools down.Hot Surface WarningThe round metal section of the detector can become hot during operation. Avoid direct contact to prevent burns.Safety ReminderKeep the smoke tester away from smoke-sensitive parts during leak detection.Do not refill oil while the smoke tester is running.If too much oil is added accidentally, drain excess oil before operation.Use SDT103 for low-pressure smoke leak detection. Do not treat it as a high-pressure A/C pressure test machine.Key FeaturesKey FeaturesSDT103 combines EVAP-focused low-pressure smoke output, visual airflow observation, adjustable smoke flow, compact portability, temperature protection, and long-term support for automotive leak diagnosis.EVAP-Focused Low PressureSDT103 is designed for EVAP system testing with output pressure around 3.2kPa / 0.46psi, helping reduce the risk of damaging EVAP pipes with excessive pressure.Quick Smoke GenerationThe tester generates smoke quickly to improve leak-check efficiency. Actual pipe filling time depends on pipe volume, adapter setup, airflow, and test conditions.Visual Airflow MeterThe external flow meter lets users observe current airflow volume, making it easier to control smoke output and protect the tested system.Adjustable Smoke FlowThe airflow regulator helps adjust smoke flow for different pipe conditions. Avoid excessive pressure and use the minimum practical airflow for the test.Compact And PortableThe compact body is easier to carry, store, and position around the engine bay compared with larger workshop smoke machines.Overheat And Anti-Frost ProtectionThe protection system shuts down power above 75°C, and the device can work normally at low temperatures down to about -20°C.External Air Source SetupConnect shop air and DC12V power, turn the flow dial counterclockwise to open airflow, then switch on the unit to start generating smoke.3-Year Warranty SupportFor eligible damage caused by non-human factors, AUTOOL provides 3-year support and replacement part assistance.

Does SDT103 Have A Built-In Air Pump? No. AUTOOL SDT103 does not have a built-in air pump. It must be connected to an external air source or shop air compressor before use. What Power Supply Does SDT103 Need? SDT103 requires a DC12V vehicle battery power supply. The comparison information lists SDT103 input as DC12V/5A. What Testing Oil Should I Use? Use liquid paraffin or baby oil as the testing liquid. Testing oil is not included due to logistics restrictions, so it should be purchased locally. How Much Testing Oil Should I Add? Add 10-15ml testing oil before first use. Do not exceed this range, and do not add more than 15ml at one time. If too much oil is added, drain excess oil before operating the machine. When Should I Refill The Oil? Refill only when the smoke becomes thin. Before adding fresh oil, pour out the remaining oil in the detector and replace the detector oil regularly. Can SDT103 Test EVAP Systems? Yes. SDT103 is designed for EVAP low-pressure smoke leak detection. Its output pressure is around 3.2kPa / 0.46psi to help prevent EVAP pipes from being damaged by excessive pressure. How Do I Control Smoke Flow? Before use, gently open the airflow regulator valve. The flow meter lets you observe current airflow volume, and the regulator helps control the smoke effect for different pipe conditions. How Long Can SDT103 Run Continuously? Do not run the detector continuously for more than 8 minutes. Allow interval rest between tests to protect the unit and maintain safe operation. What Happens If The Machine Gets Too Hot? If the device exceeds the working limit, such as over 75°C, the intelligent protection system automatically turns off the power. Wait until the unit cools before operating it again. The round metal section can become hot, so avoid direct contact. What Systems And Vehicles Can SDT103 Test? SDT103 supports low-pressure leak checks for EVAP, intake, exhaust, car sealing, various pipe fittings, fuel tank systems, crankcase air leakage, oil seals, intercooler air leaks, throttle leaks, intake air duct gasket leaks, poorly closed valves, and air or water leakage areas under proper conditions. It is suitable for many 12V cars, motorcycles, snowmobiles, off-road vehicles, ATVs, light trucks, and speedboats. Can SDT103 Directly Test High-Pressure A/C System Leaks? No. SDT103 is a low-pressure smoke leak detector and should not be used as a direct high-pressure automotive A/C pressure test machine. Use it only for suitable low-pressure smoke checks under proper conditions. Why Do Some Images Mention Fast Smoke Generation But The Use Steps Mention About 30 Seconds? Marketing and comparison images may describe quick smoke generation, while the tested pipe can take about 30 seconds to fill with smoke in real use. Actual timing depends on pipe volume, adapter sealing, airflow setting, oil condition, and test setup. What Accessories Are Included? Refer to the Packing List image for final package contents. The image shows the SDT103 main unit, retail box, DC12V battery clamp cable, smoke hose, cone adapter, intake airbag adapter, empty oil bottle, red connector, short hose, and user manual. Testing oil is not included. How Is SDT103 Different From Other AUTOOL Smoke Leak Detector Models? SDT103 is an EVAP-focused external-air-source model with visual airflow observation. Other AUTOOL smoke leak detector models differ by built-in air pump, pressure gauge, flow meter, output pressure, output flow, air/smoke mode, dual pressure mode, oil drain valve, fault indicator light, oil level gauge, and accessories.
