Digital manifolds
In addition to expert knowledge, it is above all precise measurement values which are needed for the comprehensive evaluation and correct regulation of a refrigeration plant, air conditioning system or heat pump. And it is here that the digital refrigeration measurement technology from Testo has for years proven its worth:
Digital measures better: This is what a manifold from Testo can do
Testo offer a range of digital manifold gauges to help you fulfil any and all refrigeration measurements. With your refrigeration manifold, digital measures better, and now Testo are offering a whole new range of digital manifold gauges including the testo 550i – the first fully digital manifold gauge.

What customers say about Testo digital manifolds
What else 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 analogue measuring devices and 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.
On the one hand, a leak detector is indispensable for detecting escaping refrigerant and on the other hand for discovering leaks on gas pipes. At the same time, alarms and flexible probes ensure a whole lot 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 our testo 552 vacuum gauge. Its high-precision, flexible alarm threshold values and App connection provide everything you could possibly wish for.
