Testo 557s Smart Vacuum Kit – Smart Digital Manifold with Wireless Vacuum & Clamp Probes
Quick summary
The Testo 557s Smart Vacuum Kit (0564 5571) is a wireless 4-way digital manifold kit for refrigeration, air conditioning systems, and heat pumps. It combines the Testo 557s manifold with a 552i wireless vacuum probe and 2 x 115i wireless clamp temperature probes so you can measure pressure, temperature, superheat, subcooling and evacuation more efficiently on site.

Best for
- HVAC/R technicians commissioning, servicing and maintaining refrigeration and air conditioning systems
- Tradies who want wireless vacuum and temperature measurement with app-based reporting
- Workflows where superheat, subcooling, pressure loss and evacuation checks need to be faster and easier to document
Not ideal for
- Buyers who only want a basic analogue manifold set
- Techs who need a hose-included kit straight out of the box
- Users looking for the newer touchscreen-style Testo platform rather than the 557s generation
Why tradies choose the 557s Smart Vacuum Kit
- Wireless workflow: includes a Bluetooth vacuum probe and 2 Bluetooth clamp probes for cleaner setup and less cable clutter
- Job-ready diagnostics: guided measurement menus help with target superheat, vacuum and pressure-loss checks
- Fast, clear readings: large graphic display makes results easier to evaluate on site
- Built for field work: compact, robust housing with IP54 protection
- Smart documentation: use the Testo Smart App to view readings, create reports and send results from site
- Broad refrigerant coverage: supports A3 and A2L use cases and stores 90+ refrigerants
Compatibility and setup notes
This kit is suited to refrigeration and air conditioning service work where you want one manifold paired with wireless vacuum and line temperature measurement. The manifold has 3 x 7/16" UNF and 1 x 5/8" UNF connections, so hose and adapter choice still matters depending on the systems you work on most. If you regularly service R32/R410A equipment, make sure your hose and fitting setup matches the pressure class and port sizes you use in the field.
- Refrigerant hoses – for charging, testing and evacuation setups
- Hoses & couplings – for adapters, service connections and accessory setup
- Vacuum pumps – for full evacuation workflow
- Bluetooth smart tools – for related wireless diagnostic gear

FAQs
Does the Testo 557s kit include hoses?
No. This 0564 5571 Smart Vacuum Kit includes the manifold, 552i vacuum probe, 2 x 115i clamp probes, case, batteries and documentation, but not a hose filling set.
What is the difference between the Testo 557s kit and the 557s with hoses?
The 0564 5571 kit is the smart vacuum kit without the hose filling set. The 0564 5572 version adds a 4-hose filling set.
Can I use this for heat pumps as well as refrigeration and air conditioning systems?
Yes. Testo positions the 557s for refrigeration systems, air conditioning systems and heat pumps.
Does this kit support wireless vacuum and line temperature measurement?
Yes. That is the main strength of this kit: the included 552i handles wireless vacuum measurement and the 115i probes handle wireless clamp temperature measurement.
How many refrigerants are stored in the instrument?
The current Testo AU product information and datasheet indicate 90+ stored refrigerants.
Is this suitable for flammable refrigerants?
The official Testo information states that the 557s is A3 and A2L compatible. Always follow the instrument documentation, system manufacturer guidance and Australian licensing/compliance requirements.
