Testo Smart Pressure Probe for Refrigeration
- Includes 45° angled probe connection
- Bluetooth range of up to 350'
- No hoses required - clean, simple, accurate
The Refrigeration Smart Pressure Probe easily connects to standard Schrader valves without tools and without hoses, eliminating any refrigerant loss.
The Refrigeration Smart Pressure Probe, widely recognized in HVAC and refrigeration studies, has been cited for improving measurement accuracy while minimizing refrigerant release. Industry reviews highlight its reliability and ease of use, noting that technicians appreciate the wireless connectivity and precise readings. Popularly, the probe is used for troubleshooting and system diagnostics in both residential and commercial AC units, with users reporting faster setup times and reduced risk of leaks.
The measuring device can be swiftly and simply connected directly to the pressure link. The testo 549i significantly simplifies working on pressure connections that are far apart, thanks to its wireless link to a smartphone or tablet.
Practical Benefits
Also practical: since no hoses are needed for the measurements, minimal refrigerant is lost. When used with the testo 115i clamp thermometer, individual refrigeration system parameters can also be calculated, giving technicians comprehensive system insights.
