The built in vacuum gauge allows the technician to know when they have reached the limits when evacuating a system. Building upon the easy to use platform designed by testo, the Testo 557 has 2 NTC temperature probe inputs and can simultaneously calculate superheat and subcooling in real time.
The Testo 557 is ideal for servicing, maintaining and commissioning all types of air conditioning systems. The 557 will also perform leak tests on AC/R systems with temperature compensation, insuring accurate results.
Extensive accessories included: set of 4 hoses, 2 x clamp temperature probes, precise external Pirani gauge for vacuum measurement and transport case.
Calculation of superheating and subcooling in real time for 60 refrigerants: no error-prone manual calculation.
4-way valve block for fast and efficient work.
Connection to smartphone/tablet App: remote monitoring, clever measurement documentation and refrigerant updates.
Temperature-compensated leakage test, automatic ambient pressure measurement.
250 hours‘ battery life.
