Description

Testo 549i high-pressure, the smart compact high pressure measuring instrument can be controlled via the testo Smart Probes App using your smartphone or tablet, and is ideal for carrying out servicing and troubleshooting on air conditioning and refrigeration systems.

Testo offers you greater mobility when measuring: used in conjunction with your smartphone or tablet, the handy testo 549i high-pressure measuring instrument is suitable for carrying out wireless servicing and troubleshooting on air conditioning and refrigeration systems, as well as for installing them. The measuring instrument can be set up quickly and easily, directly at the pressure connection. The testo 549i makes working on widely spaced pressure connections considerably easier thanks to wireless connection to a smartphone or tablet. Also practical: no hoses are required for measurements, meaning that no or only very little refrigerant is lost. When used in conjunction with the testo 115i clamp thermometer, individual refrigeration system parameters can also be calculated.
