Description

Testo 557 - 4-Valve Digital Manifold with Bluetooth and External Vacuum Gauge

External vacuum probe for faster and more reliable evacuation of the system
App integration via Bluetooth for fast and convenient remote monitoring and reporting via email
Measures high side / low side pressures and temperatures
Simultaneous, real-time super heat and sub-cooling
Refrigerant updates to the instrument via App

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.

Haven’t been able to use it too much yet, but it has done everything it supposed to. Has everything I was looking for. Also like the hard case and the vacuum probe that came with it.

I just received it and can't use it until a/c season starts but I'm sure it will work fine other tools I have from testo all have impressed me so I see no reason why this one will be any different

A/C Manifold

5.0

I was looking for high end manifold set mainly to impress the client but really found that i was the one impressed. A little tricky to get used to at first but this set will do everything a field tech needs along with impressing the client.
