Electronic Leak Detector – HFC / R134a / R1234yf / Hydrogen

This electronic leak detector is designed for detecting HFC refrigerants, R134a, R1234yf, and hydrogen (nitrogen-hydrogen mixture). It enables fast and precise leak detection in air conditioning systems using an electronic probe that signals the presence of refrigerant both audibly and visually (LED indicator).

Equipped with an advanced semiconductor sensor, the device offers high sensitivity and excellent detection performance, making it an ideal solution for servicing and maintenance of A/C and refrigeration systems.
