Test 557 digital manifold fulfills numerous functions, which are required for animate in addition to the reference to speaking refrigeration systems and heat pumps, in just one instrument: for example superheating/subcooling calculation, vacuum measurement, temperature-compensated leakage test. You can then use a practical app to monitor the manifold via your smartphone/tablet and growth the measurement results or send them by e-mail.
Key Features: Testo 557 set Digital manifold
-
Calculation of superheating and subcooling in real time: no manual calculation, which is prone to error
-
Connect to smartphone/tablet app: remote monitoring and smart measurement documentation
-
Precise external Pirani gauge for vacuum measurement, temperature-compensated leakage test, automatic ambient pressure measurement
-
The 60 most common refrigerants are stored in the instrument, subsequent updates possible (via app)
