Loaded with features including altitude compensation, a temperature compensated tightness test, 31 refrigerant profiles, automatic calculation of superheat and subcooling, the Testo 550 is simply on of the best values you can get.  


High Performance

Two temperature inputs allow simultaneous calculation and display of superheat and subcooling. With just a press of a button, the differential temperatures are also displayed. With another press of a button, you can quickly switch between the different measurements. The testo 550 features a large, backlit LCD display. Large numbers help you quickly and easily read the values. Intuitive operation provides you the ability to quickly analyze and diagnose the system without changing connections or performing tedious calculations.

It is built for the field. The testo 550 is a full function analyzer. With 31 refrigerant profiles stored on the processor and unique temperature-compensated sensors, the testo 550 is one of the most accurate analyzers on the market. Say goodbye to the old fashioned PT charts!

Blazing Speed

With a testo 550 Refrigeration System Analyzer, multiple tests are performed and calculated all at once. Just select the results you want displayed and away you go! Once connected, you can perform a leak test and monitor charging. Refrigerant flow can be monitored in the integrated (magnified) sight glass. Superheat and subcooling can be measured and displayed in real time!

Extremely easy to use

Two direct buttons offer you more advantages one for the display of MIN/MAX/MEAN, and the other for instant access to 31 user selectable refrigerant profiles.
Hose parks that swivel - now that's cool.

Once you go digital, analog gauges seem like a silly idea. Subcool accuracy is important. The temp clamps are he hook breaking is the only issue. Impressive tool.

I have been using this now for about 3 months and I am very pleased with the proformance of it. So much easier than carring 2 different manifolds, PT charts,and having to do the math. It takes the guess work out of problems and charging is more precise. Have found it much eisier to deal with real time numbers than guessing what a standard gauge is telling me.

The display is easy to see in all lighting conditions_The manifold valves always work well_I have owned it for 2 years now and it did not live in a case, it hung in my truck the whole time_The only failure; temp probe on left does not register_2 reasons for the 4 star rating _1.The temp clamps are very hard to position correctly on piping so the sensor is in full contact with tubing _2.The accuracy is .75% of full scale, which can equal an error of up to 5 psi _Overall a solid value.
