testo 550s AC Manifold Gauge Set – Manifold Gauges Hvac and Refrigeration – Incl. 2 Wired Temperature Clamp Probes – AC Recharge Kit with superheat, subcooling and Bluetooth

This manifold set is very easy to set up and use. Almost did not need the user manual. Unit is very solid in the hand. Wish the screen had more contrast to make it easier to read in bright sunlight. Backlight works well in shade or darkness. I like the fact that it came with signed calibration docs. I bought the Testo brand for its reputation for accuracy. Plastic case needs a little padding (which I added) for the gauge itself, but has room for wireless temp probes, hoses, other misc accessories. Very satisfied with the quality and value.

I bought this manifold a couple years ago I've used it non-stop it's never failed. I would recommend this to anyone.

The gauge is easy to use and setup. The buttons and fittings are well made and seems like it will last very long. The only bad part is the case which was damaged during delivery. If the case can't withstand delivery, then how can it protect the unit during daily use.

App is easy to use gauges are super accurate. Very nice display and readout is easy to figure out

is a gauge, a manifold, you are a tech and that the reason to buy this unit. So now why 5 starts, I had a issue with the instruments after 2 months of used, I think was software related (not able to restart and consuming the batteries fast) what I still made me keep it is the service that I got after the issue, I send a mail to Testo services and they reply faster and after I sent the instrument, they fixed no questions ask. (of course even if it was a software or hardware related I like the fast response from the service)

Awesome gauges. I can sit in the truck over 100 feet away and watch the gauge’s work over Bluetooth on my phone.
