THIKPO Smoke Machine Automotive Leak Detector with Built-In Compressor — Portable Metal Diagnostic Tester, 19–23 psi

THIKPO Smoke Machine with built-in compressor is a portable automotive leak detector that generates visible smoke to pinpoint leaks in EVAP, vacuum, fuel, intake, exhaust and other vehicle systems.

This compact, metal-bodied diagnostic tool pairs a fast warm-up smoke generator with an internal air pump, pressure gauge and flow meter so you can introduce controlled smoke into sealed systems and visually locate escaping fumes or pressure loss. It ships with a range of adapters and caps to fit hoses and ducts on cars, trucks, motorcycles, ATVs and more, and features thermal protection and adjustable output for safer, repeatable testing.

How quickly can I find a leak with this smoke tester?

The built-in compressor produces 19–23 psi and the heater can generate substantial smoke within about 10 seconds, so visible leakage appears almost immediately at the escape point. Rapid smoke output plus the included adapters reduces setup time and speeds diagnosis.

• Produces columnar smoke fast for immediate visual detection
• 19–23 psi compressor ensures thorough smoke distribution
• Multiple adapters shorten fitting and testing time

What kinds of vehicle systems will it diagnose?

It’s intended for a wide range of sealed and semi-sealed systems: EVAP, fuel lines, vacuum and intake systems, crankcase and turbocharger housings, exhaust manifolds, cooling circuits and more. Older or hard-to-access systems benefit from the varied nozzle shapes and pipe caps included with the unit.

• EVAP and fuel tank systems using optional low-pressure regulator when required
• Vacuum lines, intake tracts, throttle shafts and EGR pathways
• Turbo housings, crankcase seals, exhaust junctions and pipe assemblies

Is the smoke safe and how is the unit protected?

The THIKPO tester produces oil-based vapor intended for diagnostic use, not combustion or hazardous gas. The case is thick metal and includes an auto-cutoff safety that shuts power if internal temperature rises beyond safe limits, protecting both operator and device.

• Uses harmless oil vapor for non-destructive diagnosis
• Durable metal construction for workshop use
• Automatic thermal protection prevents overheating during prolonged operation

How precise are pressure and leak measurements?

The unit integrates a pressure gauge and adjustable flow control so you can calibrate test pressure and perform pressure-decay tests to identify tiny leaks that don’t visibly smoke. That combination makes both visual and quantitative diagnosis possible in one tool.

• Adjustable flow meter to control smoke volume
• Pressure gauge supports pressure-decay testing for small leaks
• Useful for repeatable shop diagnostics and validation after repair

Who this is for: technicians, DIY mechanics and fleet maintenance staff who need a rugged, portable smoke leak detector that works across many vehicle types. It’s especially helpful when visual inspection and vacuum tests alone don’t reveal the fault, or when you need a fast, safe way to trace leaks in EVAP, intake, fuel and sealed systems. Note: for systems specified to operate at or below 15 psi (for example some EVAP circuits), pair this device with a low-pressure regulator to match the required test pressure.
