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)
The testo 557 digital manifold fulfils numerous functions, which are required for working on refrigeration systems and heat pumps, in just one instrument: for example superheating/subcooling calculation, vacuum measurement, temperature-compensated leakage test. You can also use a practical app to monitor the manifold via your smartphone/tablet and store the measurement results or send them by e-mail.
