testo 557 - 4-Valve digital manifold kit with Bluetooth and external vacuum gaugeThe new testo 557 opens up new possibilities for efficient analysis and documentation – with Bluetooth / App integration. The wireless connection allows users to read data on a Smartphone or Tablet, quickly and conveniently. Using the App, you can e-mail measurement
reports directly from the customer job site. The App also allows you to update the stored refrigerants. The 557 now has a external vacuum probe for faster and more reliable evacuations and is suitable for all refrigeration systems or heat pumps. This compact manifold has a 4-way valve block, large backlit display and sight glass. Two NTC thermistor clamp probes provide superior accuracy of simultaneous, real-time superheat and sub-cooling readings.
The testo 557 4-valve digital manifold with 3/8 in. and 1/4 in. vacuum ports comes with a remote vacuum probe for faster and more reliable evacuations, Bluetooth, app connectivity, two clamp temperature probes for instantaneous superheat / subcooling readings, and a convenient service case.
Product Description
The testo 557 digital manifold has a 4-way valve block, a large backlit display, and a sight glass. Two NTC thermistor clamp probes provide superior accuracy for simultaneous, real-time superheat and subcooling readings. An external vacuum probe provides fast and reliable evacuation of the system. The wireless Bluetooth / app allows you to view measurement data on your smartphone or tablet, enabling you to quickly and conveniently complete and document your job. Then, be able to finalize documentation and send reports and invoice via email, right from the job site. In addition to the 60 refrigerant profiles stored in the instrument, the app can be used to download new refrigerants from the Internet, directly to the digital manifold.
