Frequently Asked Questions
The testo 557s smart vacuum kit is a comprehensive solution for HVAC/R professionals. It includes the testo 557s digital manifold with a 4-way valve block, one testo 552i wireless Bluetooth vacuum probe, two testo 115i wireless clamp thermometers, and a robust transport case. This setup allows for completely wireless, hose-free measurements of vacuum, pressure, and temperature.
The dedicated testo 557s vacuum mode provides a guided measurement menu that simplifies the evacuation process. When using the wireless vacuum probe, the testo 557s manifold displays a graphic progression of the micron levels on its large display. This allows you to monitor the "decay" and reach target vacuum levels more accurately without the clutter of additional hoses.
Yes. The testo gauges 557s are fully compatible with over 90 refrigerants stored directly in the instrument, including A2L and A3 (flammable) refrigerants. You can easily update the refrigerant list via the testo Smart App to ensure your testo 557s digital manifold is always up-to-date with the latest industry standards.
The testo 557s features powerful Bluetooth 5.0 technology, providing a radio range of up to 150 meters (approximately 492 feet) in open areas. This allows you to monitor measurements on your smartphone or the manifold display even if you are working at a distance from the service ports.
The testo 557s is built for long-term field use, offering a battery life of up to 250 hours when operated without Bluetooth and illumination. Even with Bluetooth and the display light active, you can expect approximately 100 hours of performance, ensuring the tool lasts through multiple work weeks.
While the manifold itself displays real-time data, the testo 557s integrates perfectly with the free testo Smart App. From the app, you can create professional PDF or CSV reports including site photos and customer data, which can be sent instantly via email to your office or the client.
