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