- I've received nearly a dozen requests to show the 405i. On my first call this morning I was able to record a very breif tutorial. I hope this helps those of you asking for this video. Thanks for watching!
Just purchased a 405i to check velocity in ducts on my workshop dust collection system. For those new to airflow measurements, the Testo instructions are sparse. Your video was a great help.
That's the one I use. Works like a champ.
The new app is significantly different from that shown in the demonstration. Most importantly, there is no display of CFM or option for averaging. Raw data is produced, which you can export in a table, IF the app manages to locate your mail program on it’s own. If not, well, you don’t have any option to select a mail app in the Testo app, so what you’re left with is partial, unusable raw data that you can’t export.

I will/have. I was just venting a bit at your expense. Thanks for the video though.
Every technician should know the size of there duct
What does that have to do with this video?
I keep trying to stick my in the duck... But it flys away.
Is this recommended for commercial use on exhaust fans to confirm CFM measurements after balacing has been done?
That's awesome, I'm thinking of using this on my PM's too. How would you go about using it on a system that consists of just flex? All residential installations in Australia use flex only lol... typically with a V-box coming off the supply air. Is there a requirement from coil to measuring point?
I have never used one of these before. Does this mean the maximum size duct you can use this on is the length of the rod? Say you had a 20x20 duct could you use this? Thanks.
Hi. Does the software allows you to choose another gas different from air? Or, does allow any correction for gas density change? Can the recorded data be downloaded?
Thanks!
I've got to do some more reading, but when/why would you use this tool versus the vane type? Are you using these tools more on installs or diagnosis?
I am thinking I am going to grab one of these today
Cory Desormeaux Nice! Thanks for watching!
There is also a pressure setting, and inside is written "ambient pressure" in what situation it needs to bee adjusted?
Do you know if this can be used for water tunnel? If not do you know of any hot wire anemometers for measuring water flow.
+Naman Choudhary This is for air measurements only.
Great video would you recommend it ?
Thanks!!!
Mike Cianfrocco Thanks for watching.
Good video ! good explanation. i don't own one, yet.
Cool video
hey! I would like to ask something. Do you know what is the function of this wireless sensor? Is it a normal digital sensor and transmitts the data via bluetooth? how big could be the error of this transmittion and how can affect the measurement?
Thank you in advance!
How to make model of hot wire anemometer
I just got one, anymore tips or tricks?
The black tip has a arrow on it, and it rotates a 1/4 turn.

Why didn't you buy the field piece hot wire
Eagle Mechanical Refrigeration/Hvac Durham N.C Im personally not a fan of Fieldpiece products.
I’ve never tested any ducks with my hot wire
+Alex Murphy I've never tested it on ducks either but Ive used it on several ducts... 😉🤣🤣
Its very accurate when done correctly. Multiple meadurement traverses will give the best results.
Can you change to metric measurements?
Yes
Nice, meter
Michael Lee I expect nothing less from Testo.
Too much effort to traverse a duct and too much measurement error IMHO ,.....so I don't have one. It's Florida flex duct and high velocity issues
Joe Shearer I agree. Finding metal duct around here is like seeing a Unicorn. lol
Its a flex fest here too.
Joe Shearer what are you using for airflow than Joe?
