Testo 549 Digital Refrigeration Gauges - 0560 0550

GST included.

    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.

    It precisely measures high side / low side pressure and instantly displays the corresponding saturation / evaporation temperatures for 60 refrigerants. With its integrated temperature measurement and automatic calculation of superheating/subcooling, you can now do away with additional measurements and manual comparisons (when using an optional clamp probe). 

    The versatility of 60 on-board refrigerant profiles means the Testo 549 digital manifold is the only gauge that you need. The proven, rugged design will give you years of dependable service. With optional temperature probes, the Testo 549 digital manifold provides accurate, real-time superheat and sub-cooling at the push of a button.

    The testo 549 digital manifold offers many advantages in comparison with analog manifolds. The instrument will make it easier for you to work on refrigeration systems and heat pumps.
