Accuracy That Matters – 0.25 Full Scale
When precision counts, the Testo 558s delivers. With a high level of measurement accuracy rated at 0.25 full scale, this manifold provides highly reliable data for all key parameters—superheat, subcooling, vacuum levels, and pressure readings. That means fewer call-backs, greater system efficiency, and increased customer satisfaction.
Rugged and Ready for All Refrigerants
Compatibility with Class A3 and A2L Refrigerants
The manifold supports Class A3 and A2L refrigerants, offering full functionality and safety for technicians handling modern low-GWP refrigerants. You can work confidently with A3 and A2L flammable refrigerants without concern. The device supports over 96 refrigerant types, and frequently used gases can be saved as favourites for quick access.
Whether you‘re dealing with traditional blends or the latest low-GWP solutions, the Testo 558s has you covered. Its compatibility with A3 and A2L refrigerant standards ensures you‘re always ready for the systems of today—and tomorrow.
