Today I am reviewing a specific set of Testo’s new Smart Probe Line. The Testo Smart Probes in question are the Testo 115i Wireless Pipe Clamp and the Testo 549i Wireless Refrigeration Pressure Probe which make up the Testo 0563-0002 AC/R Refrigeration Kit. All of these Testo Smart Probes handle tasks spanning from diagnosing AC system issues, residential and commercial heating & cooling systems, residential and commercial refrigeration, and more.
