Start wireless measurements on refrigeration and air conditioning systems and heat pumps straight away. This practical kit contains the testo 558s digital manifold with Bluetooth connection to wireless temperature and vacuum probes, together with a 4-hose charging set, offering the ideal basis for everyday measuring tasks.
The Testo 558s offers intuitive operation thanks to its touchscreen and clear measurement graphs on a large colour display. In addition to the touchscreen, the manifold can also be operated via keys when working with gloves. Thanks to A3 and A2L compatibility, high robustness with IP54, and a hybrid charging system comprising rechargeable and non-rechargeable batteries, the manifold is ready for every situation.
The touchscreen operation and large colour display make configuration, control and documentation much easier, and the manifold is compatible with Class A3 and A2L flammable refrigerants for maximum safety. With a wide selection of 96+ refrigerants stored on the manifold, frequently used refrigerants can be marked as favourites for quick retrieval. High accuracy of 0.25% full scale and clear measurement graphs make system analysis easy and reliable.
Readings can be recorded for up to 30 minutes and displayed as trend curves, helping anomalies to be quickly identified, with an optional extension to 72 hours of logging capacity. Readings can be directly exported and sent as a measurement report via the testo Smart App, completing documentation on site in just a few clicks. A wide range of measurement programs — superheating and subcooling, tightness testing, Delta T, evacuation or filling — can all be controlled and documented via the manifold, with free over-the-air updates keeping the instrument current.
Bringing the manifold, two clamp thermometers, a vacuum probe and a full hose set together in one kit means it's genuinely ready to work straight out of the case, without needing to source additional probes separately. A3 and A2L flammable refrigerant compatibility matters as the industry shifts toward these refrigerants, and 30-minute trend logging (extendable to 72 hours) gives real diagnostic depth for spotting system anomalies that a single-point reading would miss.
