to two external temperature probes

2-way valve block with three connections, three hose

parkers and sight glass

60 common refrigerants stored in the instrument

Display illumination for better legibility in dark surroundings

250 hours' battery life

The new testo 549 is the robust tool for daily work on

refrigeration systems and heat pumps. The robust 2-way

metal valve block with 3 connections and 3 hose parkers

allows you to work quickly and easily. The more robust

housing, with a metal frame around the display, protects the

new testo 549 even more reliably from impact. The

suspension hook guarantees secure attachment of the

digital manifold during measurement. The testo 549 is

excellently suitable for commissioning, service and

maintenance. Thanks to additional features such as the

automatic heat pump mode, which eliminates the need to

switch over the hoses, and the temperature-compensated

tightness test function, working on refrigeration systems

and heat pumps is easier than ever before.
