Description
The Testo 552i is an industry-grade wireless vacuum probe engineered for hose-free, high-precision evacuation protocols on refrigeration systems, air conditioning networks, and heat pumps. This compact smart probe connects directly to a single service port via an integrated 45° angle coupling, minimizing leak vectors and preventing refrigerant loss. It measures low-range absolute pressure profiles and automatically syncs via Bluetooth with the Testo Smart App or digital manifolds (e.g., Testo 550s, Testo 557s) for graphical tracking and process monitoring. Featuring a ruggedized IP54 protective field housing, it integrates smart vibration alarms for threshold alerts, providing a baseline asset for expert digital field testing.
B2B Applications
- Hose-Free Circuit Evacuation: Direct connection at the service valve port for deep vacuum profiling, eliminating the friction loss and outgassing associated with typical charging lines.
- Heat Pump Commissioning Diagnostics: Monitoring real-time decay and holding parameters via digital trend curves to quickly locate moisture or micro-leaks.
- GxP Service Quality Management: Automatic digital logging and exporting of standard-compliant evacuation certificates on-site via smartphone or tablet interfaces.
