Digital manifolds
In addition to expert knowledge, precise measurement values are needed for the comprehensive evaluation and correct regulation of a refrigeration system, air conditioning system, or heat pump. It is here that the digital refrigeration measurement technology from Testo has for years proven its worth:

Digital Measures Better: Testo SMART Digital Manifolds
Testo offer a wide range of digital manifold gauges to help you with all refrigeration measurements.
Testo Digital Manifolds measure better, and now we are offering a whole range of digital manifold gauges including the testo 550i – the first fully SMART Digital Manifold Gauge.
More precise measurement results with more consistent accuracy over analog manifolds
Ongoing updates of refrigerants
Automatic calculation of crucial system parameters
Be Sure with A2L Certified Instrumentation
As refrigerants with high GWP values are gradually disappearing from the market, more climate-friendly (yet flammable) refrigerants classes; A2L, A2 and A3; are becoming increasingly important due to their lower GWP and toxicity to the environment.
With these upcoming changes, you can be sure the entire lineup of Testo’s refrigeration tools are compatible with A2L refrigerants. Not to mention with the powerful testo Smart App, you will always be up-to-date with the latest refrigerants available to the market and can be synced directly to your Digital Manifold.

What customers say about Testo Digital Manifolds
I would like to say to other installers, the device really saves a lot of time, you don't have to take as much stuff with you, you don't have to do as much yourself, because the testo 557s does everything for you.
Tom Siben
Service technician at Lennox
In the past, we had to work with analoge measuring devices, needed a notepad, and we needed external temperature sensors. Testo has now incorporated all of this into a single device. This makes it much easier and much quicker for us to satisfy the customer with the performance of their device.
Peter van Vliet
Croonwolter & dros
My first impression is very positive, a very nice, new measuring set, the purchase of which you certainly won't regret as a cooling technician. I don't think any other brand can compete.

Vacuum gauges
A pressure gauge ensures that water and gas pipes, along with gas heating systems, function properly. An absolute pressure meter is in turn particularly suitable for flow measurement in ducts, laboratories and production processes, because it compensates the density here.
A Testo leak detector is an indispensable tool for detecting escaping refrigerant and gas leaks. Testo leak detectors feature alarms and flexible probes to ensure more safety and convenience.
Do you want to evacuate refrigeration systems in accordance with the manufacturer's specifications regarding absolute pressure? Then you should take a look at the testo 552 vacuum gauge. Its high-precision, flexible alarm threshold values and App connection provide everything you could possibly wish for.
