Testo 557 Digital Manifold Kit with Bluetooth, Vacuum
The Testo 557 Digital Manifold Kit includes all the features and accessories needed to analyze, charge, and evacuate air conditioning and refrigeration systems with speed and accuracy. High side and low side pressure are monitored in real time, allowing for instant saturation and evaporation temperature calculations. Included pipe clamp probes plug into the sides of the 557 and allow for real time superheat and subcooling calculations. The Testo 557 automates the slow process of multiple measurements and manual calculations. Service techs report saving an average of 15 minutes per call, with less errors and fewer call backs.
The aluminum 4-valve block on the Testo 557 refrigeration system analyzer includes both 1/4 in. and 3/8 in. ports, allowing a wide variety of configurations. With the included vacuum probe, systems can be reliably evacuated and monitored without the need for an additional micron gauge. The 557 comes loaded with 60 refrigerant profiles, and even more can be added through the Testo app. With the Testo 557 you will always have the right gauge–no matter the refrigerant, and whether you work on a mini split or a commercial HVAC system.
Built in Bluetooth allows the Testo 557 manifold to connect wirelessly to your smart phone or tablet. The free Testo Refrigeration app is available for both Apple iOS and Android products. The app allows you to monitor all measured and calculated parameters in real time. Save any test or measurement for later reporting and invoicing. With the 557 RSA connected to your device, you can even graph pressures and temperatures to see how a system behaves over time, or how it responds to a change in charge. Reports can be generated right in the app and sent to the customer or the office from your phone.
