"The Testo refrigerant manifold is an outstanding device that presents excellent value for money. It assists our a/c and chiller technicians to diagnose faults and commission systems efficiently and accurately. We had previously used the older Testo manifolds, however the Testo 550 which provides dynamic superheat and subcooling via the pipe clamp sensors has proven to bean outstanding design feature. The other key benefit is its ability to handle the vast array of refrigerants on the market with no additional attachments, this reduces our tooling costs and the amount of equipment carried by our technicians."

"I have been using the the Testo 550 digital electronic set of gauges in a classroom environment. I can now demonstrate the pressure temperature relationship that exists within an operational system with one instrument, and the students are gaining a much clearer understanding of the conditions that exist inside an operational system in real time. This equipment available to students/tradesmen. Testo products allow us to demonstrate the high quality digital equipment that is available to the modern professional."
"When the young students get the hang of the Testo 550, it only takes them two or three minutes to master compared to 10-15 minutes for older generations, It certainly helps them gather the information a lot quicker than they would using analogue gauges, and it helps them work smarter, not harder I can’t fault them. “Everything that we require Testo is happy to help with. Whether we buy devices off them or whether they come in and retrain our staff with their newer electronic gauges or data loggers, Testo is ready and waiting to help."
"The features on the Testo refrigeration manifolds are unbelievable, with the ability to monitor subheating and subcooling in real-time, as well vacuum measuring, the instruments go far beyond what analogue gauges can even dream of displaying. A further advantage is the ability to store refrigerant information on the device."
