The Testo 557 4-valve digital manifold with 3/8 in. and 1/4 in. vacuum ports come 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.
The 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 an external vacuum probe for faster and more reliable evacuations and is suitable for all refrigeration systems and 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.
