Testo 550 Digital Manifold Kit with Bluetooth

Let the Testo 550 Digital Manifold help reduce call backs and expedite your work. Analyzing and charging has never been easier or quicker. The updated Testo 550 digital refrigeration system analyzer can perform all the measurements needed to analyze and service cooling and refrigeration systems. The 550 measures high and low side pressure, and instantaneously calculates saturation and evaporation temperatures. Connect the two included NTC pipe clamp probes to the suction and liquid lines, and the 550 will display the superheat and subcool calculations in real time. Most techs report saving 15 minutes or more on each job by not having to perform as many measurements and calculations. 

The Testo 550 RSA has 60 built in refrigerant profiles, and includes a 2-way valve block with 3 connections and integrated sight glass. Additional refrigerants can be added through the free Testo app. Just add hoses and you can service almost any unit from mini splits to commercial refrigeration with just one gauge. 

Built in Bluetooth gives a level of monitoring and flexibility never possible with analog or even most digital gauges. Using the free Testo Refrigeration app for Android or Apple iOS products, you can view all measured and calculated parameters simultaneously. Or graph pressures and temperatures to understand how a system is changing over time. The app also includes reporting, allowing you to create a professional record of your work and email it to a customer or supervisor. 

The Testo 550 manifold includes a bright backlit display, visible in most any light conditions. The 4 AA batteries will power the analyzer for 250 hours. Housing improvements include a metal frame around the main unit, all wrapped inside a tough rubberized exterior. Even light rain won’t deter the Testo 550, now with a rating of IP42 (splash proof).
