Detect refrigerant leaks with the 0563 3164 reliable unit from Testo. When a leak occurs, the display turns from green to red and shows the strength of the leak. The device also emits an audible alarm to draw your attention to the screen, allowing you to react quickly. If a malfunction or contaminant obstructs the sensor, the module detects it and notifies you on the display screen, ensuring you don't get faulty readings.

This leak detector is designed to find leaks in refrigeration systems that contain common refrigerants like CFCs, HCFCs, HFCs, and hydrogen (H2). It can detect even very small leaks, thanks to its high sensitivity.

The Testo 316-4 prioritises user experience. The flexible gooseneck probe allows for precise positioning near pipes and potential leak locations. Visual and audible alarms provide instant leak confirmation. Included earphones guarantee you won't miss an alarm in noisy environments.
