Pressure Measuring Instruments

Pressure measuring instruments is a wireless pressure probe without hoses, suitable for measuring refrigerant charge in ACRefrigeration systems. It is used for servicing, troubleshooting, and documenting the operation of residential or commercial ACrefrigeration systems. When two 549i probes are used in conjunction with two 115i pipe-clamp temperature probes, it is easy to monitor superheat and sub-cooling in ACrefrigeration systems.Users can read the measurements using the Testo Smart Probes App installed on their smart device. The Testo 549i easily connects to standard Schrader valves without tools and without hoses, eliminating any refrigerant loss. The Testo 549i works on smart devices with either Android or Apple operating systems at distances up to 60 feet.
