NOTES: Consider adding options as listed above.
We highly recommend purchase of a second temperature probe for simultaneous measurement of superheat and subcooling.
Testo 550 Kit 2 (sometimes called testo 550-2) is merely a testo 550 with two clamp probes and a carry case. The carry case to make a Kit 2, is listed as an option above and is IN STOCK.
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. In a few seconds the instrument displays all of the values you need for an accurate and precise analysis.
Extraordinary Value
The testo 550 incorporate a compact design for ease of use, transport and set up. The testo 550 has a durable housing that protects the analyzer from the everyday bumps and drops. 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.

ADDITIONAL FEATURES & BENEFITS:
The Testo 550 was engineered to be a perfect balance of features, benefits and value. Features of the 550 include high accuracy pressure transducers, low mass temperature sensors, 3-way manifold configuration and magnifying sight glass. These allow a service technician to easily evaluate both sides of the refrigeration system while displaying pressures, saturation temperatures, superheat and subcooling. All of this is packed into a rugged, compact and affordable package that will fit any technician’s budget.
Lower initial cost and low cost of ownership
Keeping high quality standards in the forefront, Testo engineers had a daunting task to make the 550 more cost competitive without compromising the quality of the measurement. The outcome was a product that has fewer parts for quicker assembly, a redesign of the temperature sensors to make them more robust (while less expensive) and a more compact design.
Easy-to-use interface
The 550 has a separate button for almost everything – nine of them to be exact. More keys means eliminating the need to always scroll through multiple menus and sub menus to get to configuration settings. There is a power key for power, and back light key for the display, a setup key for easy configuration, mode keys for different modes, a refrigerant key to select over 31 on board refrigerant profiles, min/max/mean key for quick system analysis, zero key for the pressure transducers and arrow keys to make selections.
Easy-to-read display
The 550 has a brighter and better defined display than previous models. Decimal points and other display characters have been enlarged for easy viewing from a distance.
Integrated hose holder and hook
The 550 has 3 brass integrated hose parks that are positional by the user to the back or front of the instrument. Residential technicians that typically set their gauges on the ground can now do so without fear of dirt, moisture or other potential system contaminates picked up by the hose parks entering the refrigeration hoses when they are in the stored position. A relief machined into the end of the hose park allows room for the Schrader depressor and a positive seal that will keep moisture from entering the hoses in the parked position. The hook is integrated into the 550 and designed so it can easily be stored if kept in an instrument case or tool bag.
