Four valve manifold with a built-in vacuumgauge, including 2 clamp probes, integrated hook, calibration protocol, built-inhose holders, batteries and hard carrying case.
- Four-way valve block for fast and efficient servicing
- Integrated vacuum measurement supports evacuation of the system
- Two temperature probe inputs for simultaneous real-time calculation of superheat and subcooling.
- The 557 will also perform leak tests on AC/R systems with temperature compensation, insuring accurate results.
The testo 557 four valve manifold with a built invacuum gauge is the next high performance, low cost Refrigeration SystemAnalyzer from testo. The built in vacuum gauge allows the technician to knowwhen they have reached the limits when evacuating a system. Building upon theeasy to use platform designed by testo, the 557 has 2 NTC temperature probeinputs and can simultaneously calculate superheat and subcooling in real time.The 557 is ideal for servicing, maintaining and commissioning all types of airconditioning systems. The 557 will also perform leak tests on AC/R systems withtemperature compensation, insuring accurate results. The testo 557 retains therobust housing that protects the analyzer from the everyday bumps and drops.
