Testo's 316-3 refrigerant leak detector senses all CFC, HCFC, and HFC refrigerants, detecting leaks as small as 4g/a. The proven heated diode sensor provides great sensitivity down to 0.15 oz/year including the refrigerant blends like R-410A, R-407C, and R-134a.
Just turn it on and start getting readings immediately! Thanks to one-button operation and automatic zeroing, the Testo 316-3 is extremely fast. Its high-to-low sensitivity adjustment simplifies the process of pinpointing the source of refrigerant leaks.
