testo 510i - Bluetooth Differential Pressure Gauge Smart Probe

Once I paired it the first time, then turned it off, then on, it wouldn't pair the second time, so you have to swipe away the app, then relaunch it and it works. 3 'blinks' and it pairs, every time, no problems. The distance you can take your phone away before losing connection isn't great, but I still love this thing, best gas gadget for me. I do upto 8 tightness tests a day.

Being a gas engineer this is very useful but doesn't do anything that your analyser does that you probably already own,does make commission of boilers easier if you do a lot of service/repair work

Great when you attach the PDF files it creates and send them to a customer with the other various forms etc Looks really professional and also more accurate than a water manometer

510i Had one for 6 months before failing, had replaced and the “new” one will not stabilise pressure, constantly rising and falling even on completely gas tight installation, nothing to do with temperature causing oscillation as it is constantly doing it, back to liquid manometer

A bit slow on the refresu rate on the bluetooth app so need to be very slow when opening the ECV for tightness testing however once qt the right pressure the ability to leave it running and get on with the next job is a godsend

Great piece of kit. Pretty decent range too.

I'm a gas service engineer .I use the pressure leak test all day. Always on point always accurate. Really worth every penny for me. Top product.Always loved testo

It good but Bluetooth range isn't the best in my opinion. Handy app which works really well

Easy to get the hang of and use. Instructions are in German but the tool is pretty self explanatory after a few minutes and there's plenty of English translations and videos online. The major upside to this is that it's displayed through your smart device. This is helpful because you can record data and show it in graphs and tables, take a recording over a period of time and it will show you averages along with high and low points. The smart probe app let's you save and data log this info with different probes and create pdfs and other files to send to customers and clients. If you're an installer then you can save the info and prove that you've been checking and setting pressures as a way to cover your own ass. If you're like me and hope to one day own and run your own business, the data logging and customer profiles through the app are a great investment Also if you're a testo employee, and like this review, please send me some more stuff. I like freebies and will pimp out yo stuff

Sehr zufrieden.

Le Smart Probes di Testo, abbinate alla applicazione per smartphone sono ottime per le misurazioni in campo e la memorizzazione immediata delle rilevazioni. Prodotto consigliato, servizio Amazon Prime ottimo come sempre.

Fantastic tool, reliable and great value.

Une marque au top ,même si le produit consomme beaucoup les piles.
