Start your measurements on refrigeration and air conditioning systems and heat pumps straight away with the testo 558s Smart Vacuum Kit. This all-in-one solution includes the testo 558s digital manifold, 2x testo 115i temperature clamps, and a testo 552i vacuum probe, giving you the ideal tools for precise and efficient servicing and maintenance.
The testo 558s features intuitive touchscreen operation, clear measurement graphs on a large color display, and key-based controls for easy use—even with gloves.

Designed for maximum flexibility, it supports Bluetooth connectivity to wireless temperature and vacuum probes, enabling seamless data transfer and real-time monitoring.
With A3 and A2L refrigerant compatibility, an IP54-rated rugged design, and a hybrid power system using both rechargeable and non-rechargeable batteries, the testo 558s Smart Vacuum Kit is built for every challenge.

Readings can be recorded for up to 30 minutes and shown as trend curves, making it easier to detect anomalies. Optionally, the manifold’s logging capacity can be extended to 72 hours. The readings can then be directly exported and, via the Testo Smart App, can be transported as a measurement report. This allows for documentation to be completed on site in just a few clicks. With an IP54 protection rating, the 558s is built to last, with heightened durability and versatility. Superheating and subcooling, tightness testing, Delta T, evacuation, or filling: these are all measurement programmes available on the 558s which, when coupled with seamless integration and connectivity to an entire refrigeration portfolio, ensures that all applications can be managed and documented through the manifold.

The Testo 558s is able to be updated and regularly maintained thanks to free OTA updates. This enables the addition of new refrigerants, for example, or for seamless connectivity with new products. This essentially ensures that the 558s is never outdated, with consistent updates and upgrades. To simplify everyday work, measurement results can be displayed on a large color screen with clear graphs and 30-minute trend curves. With a high measuring accuracy of 0.25% full scale, reliable evaluations and analysis can be performed, ensuring accuracy when it is needed most.
