5-in-1 Air Conditioning Leak Detector for Forming Gas, R134a & R1234YF

This 5-in-1 automatic leak detector is designed for fast and professional leak detection in automotive and commercial vehicle air conditioning systems. The device supports testing of multiple refrigerants and forming gas with a single highly sensitive detector.

Using the latest semiconductor sensor technology with an integrated gas circulation pump, the device achieves a sensitivity below 3 ppm, equivalent to approximately 3 g of refrigerant loss per year.

The intelligent halogen molecule detection system significantly minimizes false alarms, making leak detection more reliable even under difficult workshop conditions.
