Take testing to the next level with the Testo 570. Coupled with the optional Easy-Kool Software, the 570 is the most powerful and feature rich analyzer available today. Data logging a refrigeration system opens a window into the refrigeration system allowing the technician to see not only what is happening, but what happened over time. The built in vacuum measurement allows the technician to know when they have reached the limits when evacuating a system. Building upon the easy to use testo 550 platform, the 570 has 3 NTC temperature probe inputs and can simultaneously calculate superheat and subcooling in real time while measuring another temperature like outdoor ambient or oil pressure or compressor current with optional probes. The 570 is ideal for servicing, maintaining and commissioning all types of air conditioning systems. The 570 will also perform leak tests on AC/R systems with temperature compensation, insuring accurate results. The testo 570 retains the robust housing that protects the analyzer from the everyday bumps and drops. It comes complete with 2 clamp probes, integrated hook, built in hose holders and a hard carrying case.
