What Testing Oil Should I Use For SDT100? Testing oil is not included due to logistics restrictions. If professional test oil is not available, buy liquid paraffin or baby oil locally and use it as the testing oil. How Much Testing Oil Should I Add? Add 10-15ml testing oil before use. Do not add more than 15ml at a time. Refill only when the smoke becomes thin, and drain remaining test oil before adding fresh test oil. If too much oil is added accidentally, drain some oil out before operation. Can SDT100 Detect The EVAP System? Yes. AUTOOL smoke leak detectors can test leaks in the EVAP system. Use the proper EVAP testing tools and adapters according to the package contents and the vehicle test port. Can SDT100 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 about 0.1MPa. SDT100 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 To Use Smoke For Segmental A/C Pipeline Auxiliary Testing? First pressurize the air-conditioning pipeline using the proper method, then spray smoke and observe whether airflow blows the smoke. If the smoke is disturbed by airflow, the location may indicate a leak point for further repair. What Systems Can SDT100 Test? SDT100 supports low-pressure leak checks for EVAP, intake, exhaust, crankcase, oil seal, intercooler air, fuel tank, coolant tank, pipe fittings, vacuum, engine airtightness, and low-pressure turbo systems. What Power Supply Does SDT100 Need? SDT100 uses DC 12V car battery power. This makes it convenient for vehicle maintenance and easy to power in typical automotive repair environments. Can The Pressure Be Adjusted? Most AUTOOL smoke leak detectors use fixed pressure. SDT MASTER allows pressure adjustment. SDT100 should be used according to its fixed safe pressure setup for common maintenance and testing needs. What Accessories Are Included? Refer to the Packing List image for the final package contents. SDT100 includes the main unit, 12V battery clamp cable, smoke hose, cone adapter, red connector, thin hose, airbag adapter, empty test oil bottle, user manual, and retail box. Testing oil is not included. What Is The Difference Among Various 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 beginners around 12 psi, and SDT203, SDT205, SDT205S, SDT206, and SDTMASTER as standard and higher-end models around 15 psi. SDT208 supports up to 35 psi. Compare air source, output pressure, flow, mode, and accessories before ordering. How Long Is The Warranty? AUTOOL provides up to 3 years of warranty support for eligible non-human damage cases. AUTOOL smoke leak detectors are sold online and offline in many countries and regions, with after-sales support for setup, accessories, and troubleshooting.Related GuidesRelated GuidesUse these related articles to understand smoke leak detector model differences, no-smoke troubleshooting, preparation checklists, and higher-end SDT model use cases.
