AUTOOL SDT205S Automotive Smoke Tester with Pressure & Flow Control

SDT205S combines separate Air and Smoke modes with a built-in air pump, pressure monitoring, and flow control. It supports low-pressure checks across EVAP, intake, exhaust, crankcase, fuel-tank, vehicle-sealing, and line-fitting systems. An oil drain valve simplifies maintenance, and the main unit is backed by 3-year warranty support. Use SDT205S with a 12V DC battery and 10–15 mL liquid paraffin or baby oil. Open the airflow regulator before testing. Use Air Mode to monitor pressure and airflow, then switch to Smoke Mode when you are ready to locate a low-pressure leak visually. SDT205S has separate Air and Smoke modes plus a pressure gauge, flow meter, and airflow regulator. Use Air Mode to watch pressure and airflow, adjust flow gradually, then switch to Smoke Mode for visual leak location. These controls do not increase the pressure allowed for the system under test. Compare AUTOOL smoke leak detector models by air source, pressure, output flow, operating mode, gauges, flow control, oil handling, vehicle power compatibility, and other model-specific features. Key features • Self-Contained Air + Smoke Modes: The built-in pump lets you check with clean airflow first, then switch to smoke for visual leak location. • Pressure & Flow Feedback: Monitor pressure behavior and relative airflow together for more context during a sealed test. • Adjustable Flow Control: Tune airflow for different pipe volumes and test conditions instead of relying on one fixed output. • Complete Sealing Adapter Kit: Includes an EVAP connector, valve-core wrench, airbag, cone, rubber plugs, and small adapter for common test openings. • Core Output and Power: Swipe or drag 1 / 1 • Monitoring and Control: Swipe or drag 1 / 1
