testo 549 - Digital manifold for beginners

Order-Nr.  0560 0550

  • 60 current refrigerants stored in the instrument

  • Additional 12 month (3 year) product warranty with registration 

  • Large 2-line backlit display 

  • Digital accuracy performs more reliably than analog manifold gauge sets for more precise readings 

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. 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). You can also use the manifold for 60 current refrigerants.

Product Description

The Testo 549 digital refrigeration gauge is a breakthrough value, making analog gauges obsolete. It precisely measures high side / low side pressure and instantly displays the corresponding saturation / evaporation temperatures for 60 refrigerants. With optional temperature probes, automatic superheat and sub-cooling calculations can be displayed.

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.

Why Make the Switch from Analogue to Digital Gauges
