testo 510i - Bluetooth Differential Pressure Gauge Smart Probe

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

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.

The 450i anemometer worked fine (screenshot attached). I did the math using the cross-section area of the duct, and the number was within 5% of than the rated output of the blower that I was to create the air flow.The app was easy to install, but asked access to my contacts and location. The manufacturer should offer options to disable this, and should not bundle reviews for all smart probes into one.Please offer the case with foam inserts to keep the probes. Thanks!

Great piece of kit. Pretty decent range too.

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.

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

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.

Fast delivery, great tool, love it
