SDT106 and SDT206: Which Smoke Leakage Detector Fits Your Work Better?

Smoke leakage detectors give users a valuable and accurate way to find leaks before those leaks create more vehicle damage. For mechanics and workshop users, a smoke machine can make diagnosis more direct because the leak path becomes visible instead of being guessed.

This guide introduces two AUTOOL smoke testers: the SDT106 and the upgraded SDT206. Both smoke machines are strong AUTOOL products and have gained popularity with many mechanic consumers. The main question is how much control and monitoring you need during leak detection work.
