Contact Instrument Solutions

Overview

The Testo 549i smart probe is a pressure probe specifically designed for servicing and troubleshooting on air conditioning and refrigeration systems, as well as for installation and commissioning. The instrument can be quickly and easily attached directly to a presure connection.

The Testo 549i's wireless Bluetooth connectivity and easy to use Testo Smart Probes App makes it easier to work on measauring points that are a long distance apart. Also since no hoses are needed, no or very little refrigerant is lost.

** The Testo 549i smart probe can be used in combination with other probes in the range, for example the Testo 115i clamp thermometer for calculating superheating parameters of refrigeration systems - please see the separate entries within the website **
