Testing oil is usually purchased locally due to logistics restrictions.Add 10-15ml OnlyFill 10-15ml testing oil before use. Do not overfill, because excess oil can reduce the space needed for stable smoke generation.Open Airflow RegulatorBefore use, gently turn the knob to open the airflow regulator valve, then choose the proper air or smoke mode for the test.Refill Only When Smoke Is ThinOnly add fresh oil when smoke becomes thin. Do not add more than 15ml each time, and drain old oil before refilling.8-Minute Use LimitDo not run the detector continuously for more than 8 minutes. Allow the unit to rest between test cycles.75°C ProtectionThe intelligent protection system stops operation when the temperature exceeds 75°C. Use the machine again after it cools down.Avoid Sensitive PartsDuring leak detection, keep smoke away from smoke-sensitive parts and avoid applying smoke to unsuitable high-pressure systems.Hot Surface WarningThe round metal part of the smoke detector can become hot during operation. Avoid direct contact to prevent burns.Safety ReminderDo not refill testing oil while the smoke tester is running.If too much oil is added accidentally, drain some oil before operation.Replace the detector oil regularly and pour out remaining old oil before adding fresh oil.If overheat protection is triggered, wait until the internal temperature drops before restarting.Key FeaturesKey FeaturesSDT205S combines air mode, smoke mode, built-in air supply, pressure observation, flow control, quick smoke output, portable structure, and smart protection for low-pressure automotive leak diagnostics.Air Mode And Smoke ModeThe built-in air pump and smoke generator allow the user to switch between air output and smoke output for different diagnostic needs.Built-In Air PumpNo additional air machine is required. The integrated air pump saves setup time and is suitable for workshop and mobile automotive repair use.Quick Smoke OutputThe smoke generator starts producing smoke quickly, helping reduce diagnostic waiting time. The connected pipe may fill with smoke after a short test period.External Pressure GaugeThe pressure gauge helps observe pipeline pressure changes. A dropping gauge reading may indicate a leak that needs further inspection.Flow Meter And Adjustment KnobThe flow meter window and flow adjustment knob help control output for different pipes, reducing the risk of using unsuitable pressure or flow.Portable DesignThe compact body, handle, hook-friendly setup, cone adapter, and airbag adapter help improve portability, storage, and inlet compatibility.Overheat And Anti-Freeze ProtectionThe protection system shuts down power when the internal temperature exceeds 75°C and supports low-temperature use under proper conditions.Oil Drain ValveThe oil drain valve helps remove old testing oil before refilling, supporting cleaner maintenance and more stable smoke output.3-Year SupportAUTOOL provides 3-year support for eligible non-human damage cases, including help with setup, accessories, and troubleshooting.SpecificationsSDT205S Product SpecificationsSDT205S is a DC 12V low-oxygen combustion smoke leak detector with built-in air pump, <15psi rated pressure, <6L/min rated output flow, 65W power, air and smoke mode output, pressure gauge, flow meter window, flow adjustment knob, and oil drain valve.Core SpecificationsProductAUTOOL SDT205S Automotive Smoke Leak DetectorWorking PrincipleLow oxygen combustionInput PowerDC 12VTest Oil Filling Volume10-15mlRecommended Testing LiquidLiquid paraffin or baby oilRated Output Pressure<15psiRated Output Flow<6L/minRated Power65WHigh-Temperature ProtectionStops working above 75°CNet Weight Of Main Unit3.2kgGross Weight / Package Reference3.7kgFunction ConfigurationAir Source TypeBuilt-in air pumpMode OutputAir mode / Smoke modePressure GaugeYesFlow Meter WindowYesFlow Adjustment KnobYesOil Drain ValveYesFault Indicator LightYesOil Level GaugeNo Core SpecificationsWorking PrincipleLow oxygen combustionInput PowerDC 12VTest Oil Filling Volume10-15mlRated Output Pressure<15psiRated Output Flow<6L/minRated Power65WProtectionStops above 75°CMain Unit Weight3.2kg Function ConfigurationAir SourceBuilt-in air pumpMode OutputAir / SmokePressure GaugeYesFlow Meter WindowYesFlow Adjustment KnobYesOil Drain ValveYesOil Level GaugeNo How To UseHow To UseUse SDT205S with a DC 12V battery and 10-15ml liquid paraffin or baby oil.

What Testing Oil Should I Use For SDT205S? If professional test oil is not available, buy liquid paraffin or baby oil locally and use it as the testing oil. Testing oil is usually not included due to logistics restrictions. How Much Testing Oil Should I Add? Add 10-15ml testing oil before use. Do not add more than 15ml each time. Refill only when smoke becomes thin, and drain remaining test oil before adding fresh oil. If too much oil is added accidentally, drain some oil out before operation. Can SDT205S Directly Test Automotive A/C System Leaks? No. The automotive A/C system operates at about 1.7-3.0MPa output pressure, while AUTOOL smoke leak detectors generate much lower pressure. SDT205S cannot directly pressure-test the automotive A/C system for leaks. It can only be used for segment-assisted air-conditioning pipeline checks under proper conditions. How Can I Use Smoke For Segment-Assisted A/C Pipeline Checks? First pressurize the air-conditioning pipeline using the proper method, then spray smoke near the suspected area and observe whether airflow blows the smoke. If the smoke is disturbed by airflow, that location may indicate a leak point for further repair confirmation. Can SDT205S Detect EVAP System Leaks? Yes. AUTOOL smoke leak detectors can test EVAP system leaks. Use the proper EVAP testing tools and adapters according to the package contents and the vehicle test port. What Systems Can SDT205S Test? SDT205S supports low-pressure leak checks for intake systems, exhaust systems, car sealing, crankcase systems, fuel tank systems, EVAP systems, vacuum-related pipes, and various pipe fittings. It should not be used as a direct pressure tester for high-pressure A/C systems. What Power Supply Does SDT205S Need? SDT205S uses DC 12V car battery power. This makes it convenient for typical automotive repair environments where a 12V vehicle battery is available. Can The Pressure Of The Smoke Leak Detector Be Set? Most AUTOOL smoke leak detectors use fixed safe pressure, except for SDT MASTER, which allows pressure adjustment. SDT205S includes a flow adjustment knob for flow control, but it should still be used within its designed low-pressure testing range. What Accessories Are Included? Different AUTOOL smoke leak detector models may include different accessories. Typical smoke leak detector packages may include rubber adapters, cone adapter, airbag adapter, EVAP testing tools, smoke hose, power cable, test oil bottle, user manual, warranty card, and certificate of qualification. Refer to the final SDT205S package contents before ordering. What Is The Difference Among AUTOOL Smoke Leak Detector Models? The AUTOOL smoke leak detector series includes SDT101 and SDT103 for EVAP systems around 3.2Kpa, SDT106 and SDT202 for beginner-level use around 12psi, and SDT203, SDT205, SDT205S, SDT206, and SDT MASTER as standard and higher-end models around 15psi. SDT208 supports up to 35psi. Compare air source, pressure, flow, mode output, flow meter, flow adjustment, oil drain valve, and accessories before ordering. How Long Is The Warranty For SDT205S? AUTOOL provides up to 3 years of warranty support for eligible non-human damage cases.
