This  is a high sensitivity halogen leak detector designed with a sensitive semiconductor diode sensor for detecting various halogenated refrigerants.

The thermistor leak detector (HD2) is currently the most sensitive and reliable portable tool for accurate detection of refrigerant leaks in a wide range of applications, including car air conditioning, cold storage facilities, automotive refrigeration systems, and residential, commercial, and industrial refrigeration equipment. This tool is essential for refrigeration and air conditioning technicians and service engineers. It is recommended to carefully read the instructions before use.

Features:

It is used for detecting R134a, R12, R22, R502, R404a, R407, and other refrigerants.

Comes with both AC adapter and backup battery for flexible operation.

Equipped with a tough and durable case for maximum protection and storage.

Note:

The HD2 leak detector is designed to identify halogen refrigerants (CFC, HCFC, HFC) with very small leaks.

Ventilation is recommended before entering a closed space if a large refrigerant leak is suspected, as high concentrations may displace oxygen and pose a hazard.

This detector cannot identify ammonia, carbon dioxide, or hydrogen refrigerants.

When the indicator light is displayed, the detector is in manual mode; press the function key once or manually to reset.
