Kryon Heated Diode Leak Detector

This electronic leak detector with heated sensor uses a microprocessor and a semiconductor sensor to provide accurate and realistic detection signals. It is capable of identifying even very small leaks, thanks to adjustable sensitivity and a 7-LED tricolor visual scale that gives an immediate indication of the presence of gas.

The device is designed to detect a wide range of refrigerant gases (including HFCs, HFOs, 1234yf, and blends), as well as nitrogen-hydrogen mixtures (commonly used for pressure testing). The 40 cm flexible stainless steel probe facilitates access to critical points in the system.

The package includes a 220 V power adapter with MicroUSB output, allowing the device to be powered directly; the AA alkaline batteries required for operation are not included. The unit is supplied with a calibration certificate issued by an accredited laboratory, which can also be used for F-Gas certification purposes.
