The new testo 549 is the robust tool for daily work on
manifold during measurement. The testo 549 is excellently
refrigeration systems and heat pumps. The robust 2-way
suitable for commissioning, service and maintenance. Thanks
metal valve block with 3 connections and 3 hose parkers
to additional features such as the automatic heat pump mode,
allows you to work quickly and easily. The more robust
which eliminates the need to switch over the hoses, and the
housing, with a metal frame around the display, protects the
temperature-compensated tightness test function, working on
new testo 549 even more reliably from impact. The
refrigeration systems and heat pumps is easier than ever
suspension hook guarantees secure attachment of the digital
before.
