Testo-557-Set Digital Manifold Gauges HVAC (Bluetooth)

No. 0563 1557

The testo-557-Set Digital Manifold Gauges HVAC (Bluetooth), 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.
