I needed a handheld air flow meter that allowed for a wide range to verify built in instrumentation. Feel like I found gold in the 510i manometer. It has no screen, only a light and a button. All readings feed through this app which i configure and feed identifiers to. The exported csv files include everything making my documentation work easy as can be.I don’t know why i need one of these manometers for home, but i want one. Probably should avoid looking at FLIR tools while i still have a checking balance.

we recently began using the 550S combined with the smart app. While the 550s works very well as a stand alone manifold the app is doesn’t generate reports or show the pressures at the top of the screen. The only work around we have found is screen recordings if you’re using iPad or an iPhone. The pressures are shifted to the bottom of the screen into small blocks. The lack of its ability to generate reports is a deal breaker for us. The app does not work as advertised. It’s a shame really the instrument it’s self works great. If your team requires proof prior to new unit commissioning. This app is not for you.

Changing favorite refrigerants doesn’t “stick”. You remove one and it just goes back to a favorite. Since you can only have 5 I can’t add any which means I spend a ton of time on jobs scrolling through refrigerants. Restore to factory settings on the gauges retains the favorites from the app (with the app closed and phone not connected). I wanted to get something better but guy on marketplace that wanted to buy them has the same problem and I refunded him because he claims the product (or app) is defective.

As with many other frustrated users. After using the old app successfully for years. I removed then replaced the old "testo Smart Probe App" with the new "testo Smart App". As other users stated. Once launched, It continues to ask you to install the new app. Clicking on install, takes you back to Apple apps which then gives you the option to open the app. This occurs every thine the app is opened. Also when using the 605i (even with fresh batteries). Bluetooth range averages 7-8 feet. It’s as if the refer walls are blocking the signal. Paid hundreds of dollars for the Testo kit with (1) 605i, (2) 549i. Having not used the 549i yet. I’m sure their quality… Though, did I make the wrong choice of equipment, due to poor software design. Their useless without the integration.

I am a commercial/industrial chiller technician, and I use my testos daily. Absolutely love them, have had them since I first got in the field. However, recently I am noticing that the saturation temperature is displayed at the bottom of the UI, on its own tab now. Instead of directly under the pressure reading. Not sure if it is a bug or new addition, however I’m severely concerned. This makes referencing less easier and less comfortable than it used to be, and I would love to see it be able to be toggled, or removed.

Hello,I am an HVACR student in college and use Testo probes. Overall I love the tools themselves however as other students began to buy and use their own a major issue has arisen. The Testo app scans for probes to connect to in the background, normally if your the only one with probes this isn’t an issue. However if someone within range (ie 10’ away) is also using Testo probes, the app will also try to connect to his/her probes and their phone to your probes. As far as I know there is no way to turn this automatic scanning and connecting off.Please Testo update the app to allow users to toggle discovery of new probes. Or at least blacklist new probes so that the app will not try to connect to 14 other peoples probes.

So you show up to a site to get a job done and you find out that they lock you out of the app you’ve already downloaded. And you need to download a new one refusing to let the old one work. Real intelligent Testo because you know yeah I just happen to not have Wi-Fi out in the middle of nowhere then of course even if you set Apple up so that anything that’s a free download doesn’t require a password because I don’t memorize 1000 passwords I need for my lifetime I guess I’m just not gonna be able to download it so sure I’ll go back down to the van and get my gauges. I don’t know what knucklehead green lit that operation but they basically just cost himself a customer who has thousands of dollars of their equipment.

Love the Testo probes but have constant issues with getting the app to recognize the probes. Once connected they work fine and stay connected but if I take my device out of range, close the app, or turn off a probe, then most times they will not reconnect. The only recourse is to remove the app from my device and then reload it and start from scratch. This has been the case for years and new app updates have done nothing to improve it. Again love the probes but the connectivity issues make me want to throw them across the yard. Probes get a 4.5, app gets a 1.

I’d rate it a full five stars but while in refrigeration measurement you cannot record either supply, return or ambient at the same time.If I can add this to my field report, which is honesty way nicer than the fieldpiece job link app, I’d change this to five stars.It is however a very nice software to record real time data for customers and the graphs really do help you catch problems the naked eye normal wouldn’t see. There’s also different measurements that make this the best hvac app in the trade.

I loved my gauges until this update took over my equipment. Now my unit is unable to be used with my phone. It seems to be stuck in download mode. Anything I try to do the app tells me to download which I did many times. Then it tells me my Bluetooth connection isn’t on yet somehow it has the readings. Add this to the fact I was on a job which I couldn’t complete because of this upgrade makes me wish I had chosen a different mfg to get equipment from. I will probably by a different system now and throw this piece of crap away. Bad thing is that testo already got my money.
