AUTOOL SDT100 Smoke Machine for Vacuum Leaks with Built-In Pump

SDT100 combines EVAP and vacuum smoke leak detection with a built-in air pump for low-pressure systems. Grouped controls keep the main switches and connections easy to identify. Automatic overheat and low-temperature protection, 12V vehicle compatibility, and 3-year main-unit warranty support round out the core features. Use SDT100 with a 12V DC battery and 10–15 mL liquid paraffin or baby oil. The connected test line can fill with smoke in about 30 seconds, allowing visual leak detection. SDT100 has a built-in air pump and fault indicator, but it does not show pressure or airflow readings. Use visible smoke to locate permitted low-pressure leaks and follow the service limits for the system you are testing.
