Struggling with Hidden Car Leaks?
Hidden leaks are hard to detect and often lead to increased fuel consumption, reduced engine performance, and EVAP or exhaust system faults. Manual inspections are slow and may cause unnecessary component damage.
Common Issues:
Hard to Detect – Small leaks are difficult to find with traditional methods
Wastes Fuel – Leaks reduce fuel efficiency
Engine Performance Drops – Affects stability and power output
Slow Manual Checks – Time-consuming inspections
Risk of Damage – Prolonged leaks harm components
EVAP / Exhaust Faults – Triggers warning lights and emission issues

Dual Testing Modes: AIR Mode + Smoke Mode
AIR Mode:
The device first uses AIR mode to measure system pressure and detect potential leaks. A pressure reading below 0.5 bar indicates a definite leak, while a reading of 0.8 bar or higher confirms excellent system sealing. No smoke is required when the system is properly sealed.

Smoke Mode:
If a leak is detected in AIR mode, switch to Smoke mode to accurately locate the leak. Smoke visually highlights even small leaks,
making the diagnostic process faster and more precise.

Overheat & Anti-Frost Protection
Overheat Protection:
The device automatically activates power protection and shuts down when its temperature exceeds 75 °C, preventing damage and ensuring safety.

Anti-Frost Protection:
Designed to operate reliably in extreme cold, the device can function normally at temperatures as low as -20 °C.

How to Judge a Leak
No Leak: Pressure gauge stable → system airtight.
Minor Leak : Pressure gradually drops → small leak.
Major Leak : Pressure drops to zero → large leak.
Minor Leak : Pressure gradually drops → small leak.
Major Leak : Pressure drops to zero → large leak.
How to Perform a Leak Detection
Prepare the Detector: Add 10ml of baby oil to the detector for the initial operation.
Position the Detector: Open the engine cover and securely suspend the detector in a stable position.
Connect the System: Disconnect the target pipe or component and attach the detector properly.
Power On: Connect the detector to a DC 12V power source and switch it on; the device will begin operation.
Smoke Filling: Allow approximately 30 seconds for the system or pipe to fill completely with smoke for accurate leak detection.
