Measures high-side or low-side refrigerant pressure (or both simultaneously with 2 probes) in ac/refrigeration systems
Not hoses required! clean, simple, accurate
Low-loss refrigerant pressure testing
Use with 115I pipe-clamp temperature probes for automatic superheat/ sub-cooling calculations
The Testo 549I SMART probe is a hose-less, wire-less, pressure probe for measuring refrigerant charge in AC/refrigeration systems. It is used for servicing, troubleshooting, and documenting the operation of residential or commercial AC/refrigeration systems. When two 549I are used in conjunction with two 115I pipe-clamp temperature probes it is easy to monitor superheat and sub-cooling in AC/refrigeration systems. made in United States.
