Smart Probes AC and Refrigeration Test Kit Testo
The Testo Smart Probes AC and refrigeration test kit is a compact wireless instrumentation array engineered for technical servicing, systematic troubleshooting, and installation of air conditioning and refrigeration plants. The specialized professional bundle contains four high-performance instruments: two Testo 549i high-pressure gauges and two Testo 115i clamp pipe thermometers. This application-specific configuration operates entirely without cooling lines or manifold hoses, transmitting diagnostic field readings directly to a smartphone or tablet via Bluetooth up to an extended 100 m radius. Synchronized with the Testo Smart App, it delivers automated live evaluation of system superheating and subcooling conditions for more than 90 built-in refrigerant profiles.
Industrial Applications
- HVAC System Balancing: High-speed maintenance adjustments, operating parameters evaluation, and compression side cross-checks on refrigeration systems.
- Dual Side Circuit Diagnostics: Simultaneous real-time analysis of suction-side and liquid-line parameters across climate units.
- Refrigeration Plant Commissioning: Wireless pressure and surface temperature tracking for advanced safety and leakage protocols.
