Description
The Testo 550s Smart Kit with filling hoses is a versatile industrial measurement solution configured for swift commissioning, preventative maintenance, and complete digital servicing of refrigeration units, heat pumps, and air conditioning systems. The set features the Testo 550s digital manifold engineered with a large graphic display and a rugged 2-way valve block. For maximum field flexibility, it includes a heavy-duty 3-hose filling set and two Testo 115i wireless clamp thermometers that connect automatically via Bluetooth. This industrial kit supports streamlined data logging via the Testo Smart App and is certified safe for operation with Class A3 and A2L flammable refrigerants under tough environmental criteria, protected within an IP54 certified housing.
B2B Applications
- System Diagnostics and Verification: Wirelessly executing rapid calculations for superheating and subcooling values across low- and high-pressure system loops.
- Refrigerant Charging Workflows: Using the 3-hose assembly for robust pressure charging while simultaneously logging continuous system response parameter trends.
- Preventative Leak and Stablity Profiling: Conducting app-guided pressure drop tests to confirm absolute circuit tightness before equipment commissioning.
