Testo 0560 2549 03 549i High-Pressure Gauge - Wireless HVAC Refrigerant Probe 2nd Generation

HVAC technicians, this Testo 549i smart probe is seriously advanced technology for refrigerant work!

The second-generation design is completely wireless and hose-less, connecting directly to standard Schrader valves without tools and without any refrigerant loss during connection.

The 45-degree angle makes it easy to read and access even in tight spaces.

When used with the Testo Smart Probes App on your Android or Apple device, you can monitor pressures from up to 350 feet away - no more running back and forth between the unit and your gauges.

What's really powerful is using two 549i probes with two 115i pipe-clamp temperature probes to monitor both superheat and sub-cooling simultaneously.

This makes servicing, troubleshooting, and documenting AC and refrigeration systems incredibly efficient and accurate.

The probe works on residential and commercial systems alike, and the wireless capability means no more tangled hoses or limited mobility.

The measurements display clearly on your smart device, and you can save and document readings for client records or future reference.

Whether you're doing routine maintenance, diagnosing problems, or verifying system performance, this Testo probe delivers professional-grade accuracy with modern convenience.

It's one of those tools that changes how you work for the better, saving time and improving service quality with every job.
