The Testo 549 digital manifold is a breakthrough with unheard of value, truly making analog gauges obsolete. It precisely measures high side / low side pressure and instantly display the corresponding saturation / evaporation temperatures for 60 refrigerants. Rapid, 1/2 second updates on the backlit display make it easy to spot fast changing system trends in real-time and the 0.5% full scale accuracy of the pressure sensors help you nail down operating conditions.

With optional temperature probes, automatic superheat and sub-cool calculations are instantly displayed. 

NOTE: Pipe clamp probes are optional. You can add them in the recommended items area below 

The versatility of 60 on-board refrigerant profiles means the Testo 549 digital manifold is the only gauge that you will ever need for almost all AirConditioning and refrigeration installation or service work, ranging from large tonnage systems to mini-splits.
