Testo 550-2 Set Digital Manifold For Refrigeration Systems And Heat Pump

testo 550 is the robust tool for daily use on refrigeration systems and heat pumps. The robust 2-way metal valve block with 3 connections and 3 hose holders allows fast and easy work. The solid housing reliably protects the testo 550 from knocks. During measurement, the suspension hook guarantees secure attachment of the digital manifold. The vacuum display informs of the vacuum reached during evacuation. This makes the testo 550 excellent for service, maintenance and commissioning tasks. Thanks to further instrument functions such as the automatic heat pump mode, which makes switching over the refrigerant hoses superfluous, and the temperaturecompensated tightness test function, work on refrigeration systems and heat pumps is easier than ever. testo 550-2 set digital manifold, 2 clamp probes for measuring on pipes, transport case, calibration protocol and batteries Pressure: Measuring range: 50 bar.
