Testo 558s Digital Manifold Kits
Testo 558s Digital Manifold Kits combine a digital 4-way manifold with wireless probes for servicing and maintaining refrigeration systems, air conditioning systems and heat pumps. Smart Vacuum versions include two Testo 115i clamp thermometers and a Testo 552i vacuum probe, while Heat Pump versions add a Testo 560i refrigerant scale, a refrigerant valve and a Testo 770-3 clamp meter. Choose the kit configuration with the hose set and sight glass options required for your work.
Using the colour touchscreen, physical keys or Testo Smart App, you can control measurement programmes for superheating, subcooling, tightness testing, temperature differences and evacuation. Bluetooth links the supplied temperature and vacuum probes to the manifold, while measurement graphs help you assess readings and identify changes during testing. For charging work, the Heat Pump Kit’s scale and valve support automatic filling to a target weight, superheat or subcooling, and the app lets you export and send measurement reports from site.
Key Benefits
- Physical keys let you operate the manifold while wearing gloves
- Colour graphs make system readings easier to assess
- Refrigerant favourites provide quick access to frequently used entries
- Trend curves show how readings develop over a 30-minute period
- Wireless probes send temperature and vacuum readings to the manifold
- Hybrid power combines USB-C recharging with replaceable batteries
- Over-the-air updates can add refrigerants and support for new instruments
- The Heat Pump Kit’s clamp meter supports True RMS and inrush current measurements
