The Testo 552i is an App controlled wireless vacuum probe that can either display values on a smart device or into a Testo refrigeration manifold. The instrument can be quickly and easily attached directly to a pressure connection.
The Testo 552's wireless Bluetooth connectivity, compact size and easy to use Testo Smart Probes App makes it easier to work on measuring points that are difficult to access. Also since no hoses are needed, no or very little refrigerant is lost.
** The Testo 552i smart probe can be used in combination with other probes in the range, for example the Testo 115i clamp thermometer and Testo 549i high pressure smart probe used for calculating superheating parameters of refrigeration systems - please see the separate entries within the website **
