Testo 316-3 Refrigerant Leak Detector
The Testo 316-3 Refrigerant Leak Detector helps refrigeration and air conditioning engineers locate refrigerant leaks quickly and accurately. Its high sensitivity allows detection of very small leaks, helping reduce downtime and refrigerant loss. In addition, the instrument is simple to operate and ready for use within moments of switching on.
Designed for professional servicing work, the Testo 316-3 Refrigerant Leak Detector identifies a wide range of refrigerants including CFCs, HFCs and HCFCs. Automatic zeroing supports reliable measurements even in areas where refrigerant may already be present. As a result, users can work with greater confidence in demanding environments.
Reliable Leak Detection Performance
High sensitivity of less than 4 g/a enables the detection of even very small refrigerant leaks. Visual LED indication works alongside an audible alarm to provide clear leak warnings. Furthermore, the responsive sensor helps users pinpoint leak locations efficiently during maintenance inspections.
The Testo 316-3 Refrigerant Leak Detector requires no refrigerant characteristic selection before use. This simplifies operation and reduces setup time on site. Consequently, technicians can move between jobs more efficiently while maintaining accurate leak detection performance.
Built for Everyday Service Work
Lightweight construction and ergonomic handling make the instrument comfortable to use throughout the working day. The sensor can also be replaced quickly, reducing service interruptions and helping maintain productivity. In addition, the robust design supports long-term use in professional refrigeration applications.
Two different set types are available, allowing users to select the package that best suits their requirements. The Testo 316-3 Refrigerant Leak Detector is supplied to meet recognised industry standards and refrigerant leak detection regulations. Therefore, it is a dependable solution for routine inspections, servicing and fault finding.
