The Testo Smart Diagnostics Kit combines two Testo 549i pressure probes with the Testo 770-3 Clamp Meter. The kit is compatible with the free Testo app, where all data, including live readings and job site photos, can be shared or exported.
Technicians can measure high and low-side pressures without cumbersome hoses, while the app automatically calculates critical parameters. The 770-3 measures current, voltage, and continuity, enabling fast identification of electrical faults.
Please visit our 770-3 Clamp Meter and 549i High-Pressure Gauge Smart Probe listings if you require further information on the products.
