Testo 316-3 – Refrigerant Leak Detector

The Testo 316-3 is able to detect the smallest refrigerant leaks with a sensitivity of 4 g/a. Conforming
with F-gas regulations.

Kit Includes sensor tip, transport case, calibration protocol, batteries, filter and instruction manual


The new Testo 316-3 refrigerant leak detector delivers optimal sensitivity to all CFC, HCFC, and HFC refrigerants, detecting leaks as small as 4g/a.
By design the 316-3 is resistant to contaminants such as rust, dirt and oil.
Productivity features allow users to decrease sensitivity to pinpoint leak sources compensating for refrigerant buildup or pooling allowing the service technician to quickly locate even the smallest leaks.
