This automotive smoke machine leak detector is designed to help identify hidden leaks in vehicle systems for faster diagnostics. It supports testing on EVAP lines, vacuum hoses, intake passages, turbo piping, and exhaust systems. Dual testing modes let you check system sealing with air first, then visually locate leaks with smoke. Built-in dual air pumps, a pressure gauge, and a flow meter help improve detection accuracy. It is suitable for cars, motorcycles, trucks, boats, and ATVs.
