The testo 550s Smart Kit is the ultimate solution for wireless measurements in the commissioning, servicing, and maintenance of refrigeration systems, air conditioning systems, and heat pumps. This HVAC Digital Manifold Gauge Set includes the testo 550s smart digital manifold, featuring Bluetooth connectivity and a durable 2-way valve block.
To ensure maximum flexibility on-site, the kit comes equipped with two testo 115i wireless temperature probes (Bluetooth, NTC), allowing for cable-free temperature readings, and a robust transport case for secure storage. As a high-precision wireless digital manifold, it acts as a comprehensive refrigerant pressure gauge that simplifies complex tasks through automated calculations and seamless smartphone integration. Additional Bluetooth probes, such as the testo 552i for wireless, hose-free vacuum measurements, are available separately to further expand the capabilities of your kit.
Delivery Scope
- testo 550s digital 2-way manifold including batteries (4 x AA) and calibration protocol
- 2 x testo 115i wireless Bluetooth clamp thermometers
- Transport case
- testo Smart App (free download)
- Instruction manuals
Frequently Asked Questions
The testo 550s Smart Kit focuses on complete wireless freedom. Unlike the basic kit which uses cable probes, this kit includes two testo 115i wireless temperature probes. These Bluetooth-enabled clamps allow you to measure temperatures on pipes up to 100 meters away from the manifold without the clutter of wires.
Yes. This HVAC digital manifold gauge set connects via Bluetooth to the testo Smart App. You can view real-time data, generate professional reports, and send them via email directly from your phone.
Absolutely. This refrigerant pressure gauge comes pre-loaded with over 90 refrigerants. The list is automatically updated through the testo Smart App, ensuring compatibility with A2L and other modern refrigerants.
The testo 550s smart digital manifold is built for the toughest environments. It features an IP54 protection class, making it resistant to water splashes and dust, and a rugged housing designed to withstand accidental drops.
While the testo 550s can indicate vacuum, for precise and hose-free evacuation monitoring, we recommend pairing the kit with the testo 552i Bluetooth vacuum probe (sold separately), which integrates directly with the manifold display.
