Testo 549i – Refrigeration Pressure Smart and Wireless Probe

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.

Key Features:

  • Measures high-side or low-side refrigerant pressure (or both simultaneously with 2 probes) in AC/refrigeration systems
  • No hoses required! Clean, simple, accurate.
  • Low-loss refrigerant pressure testing!
  • Use with 115i pipe-clamp temperature probes for automatic superheat / sub-cooling calculations
