Testo 550s Smart Set Digital Manifold with Bluetooth and Clamp Probes 0564 5502

The Testo 550s Smart Set is a digital manifold engineered for HVAC/R professionals who demand precision and efficiency. Its standout feature is the automatic calculation of superheating and subcooling, eliminating manual errors and speeding up system diagnostics. The manifold measures pressure from -1 to 60 bar with ±0.5% full-scale accuracy and 0.01 bar resolution, while the included clamp probes measure temperature from -50 to +150 °C with ±0.5 °C accuracy. Connect via Bluetooth 5.0 LE to the Testo Smart App for live data logging, report generation, and access to 90 stored refrigerants, with updates available over the air.

Advantages

This set streamlines your workflow with guided menus for commissioning, service, and maintenance. The temperature-compensated leak test detects even minute refrigerant losses, and the external vacuum probe connection allows for precise evacuation measurements. The backlit graphic display ensures readability in dark mechanical rooms, while the IP54 rating protects against dust and splashing water. With a battery life of up to 250 hours, you can rely on it for long workdays without frequent changes.
