Testo 552i App-Controlled Wireless Vacuum Probe

Overview

The Testo 552i enables wireless vacuum measurement using a single service port. This Bluetooth®-enabled, app-controlled vacuum probe expands the selection of testo Smart Probes and offers the best support for the correct evacuation of cooling and heating systems as well as heat pumps, delivering accurate measurement data in a durable, easy-to-use design.

Measuring from 0 to 20,000 micron (0 to 26.66 mbar) with fine 1-micron resolution at low pressures, the testo 552i lets you follow the evacuation process live in the testo Smart App, set target thresholds and document results. Because it connects wirelessly, there are no extra hoses to route, and it can be combined with a testo 550s or 557s manifold for a complete cable-free service workflow.
