testo 410i - Bluetooth Vane Anemometer Smart Probe

If you do any refrigeration work. These things are absolutely brilliant. I coupled mine up with a low loss valve. So I can attach it to the service valve easily and then screw down so there is little to no loss of refrigerant.But these themselves as it's a small probe screwing on to the service/schrader valve itself shouldnt cause too much loss, unlike having a hose.Connects to my phone/app easily. These are my go to whenever doing refrigerant for checking subcool/superheat. Diagnostic work. Nitrogen pressure testing.Come in the nice little protective case. Never leave these out of my work van. Goes to every job. Can use the temperature probes for other applications in my industry to get the temperature of certain equipment.

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.

We use these when checking heating circuit flow and return temperatures to ensure correct balancing of the heating circuit either UFH or Rads.Now forms part of the CP1 Heat Networks recomendations.

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 etcLooks really professional and also more accurate than a water manometer

I bought this to monitor how quickly electronic products heat up with usage. Keep in mind infrared readings vary tremendously based on what surface, and shiny metallic surfaces are way off if you don't adjust the emissivity coefficient. Test also makes a contact thermistor probe, the 115i, that can be a better fit.That said, this probe is relatively inexpensive for a quality instrument (I don't trust the no-name Chinese junk, even if this is also made in China for a German company). The ability to measure trends using the smartphone app is very valuable, and would cost two arms and a leg with Fluke.

Found it very easy to connect to the Testo software on my phone.. very impressed…

Great piece of kit. Pretty decent range too.
