BTMETER Por CFM Anemometer Wind Gauge with 600Set Data Storage Export to PC | Airflow Velocity Meter Handheld Measure Wind Speed Flow Temp for HVAC, 0.1~100 mph, Vane Sensor Backlight MAX MIN AVG BT-846A

I’m not a pro, so probably don’t have enough knowledge to evaluate this device fully, but it seems to serve its purpose very well. The handheld sensor (impeller) is lightweight and very low friction. Doesn’t take much air movement to spin it and register a flow rate. Often times I won’t even use the digital console when I’m just looking to see if I have some air flow or nothing. There’s plenty of modes and features in the digital console, but I only use the most basic ones. There’s plenty carrying and storage case is nice to have as I don’t use it much.

I have used this HVAC monitoring meter for about a week and it seems well made, accurate and surely easy to read and use. I am impressed that the battery box is sealed from moisture by an O-Ring gasket and two small screws. Shows attention to detail by the designer and manufacture. A week of use is too early to say much more but I expect it to have a long and useful life in my tool kit. Alan

This ¨anemometer¨ work like a charm. Having the anemometer separate form the meter was a great idea for many reason, not only allows you to take accurate temperature without exposing the meter it shelf, but when you have to take flow and velocity from a duct above your head (on a 8ft ladder) you can see the reading and make adjustments with removing the "anemometer" from its position. Very accurate by comparing with another brand. The only reason to give four star was for the instruction or manual I should say. For a person that doesn't have used this type of equipment, the instruction require a little more explanation. Other than that I highly recommend the product.

Great tool for doing HVAC diagnostics among other things. For the price very good quality and accuracy.

Pros: 1-big display 2-Adjustable handheld device makes it easy to read in places where access may be difficult 3-makes your life easy by doing the CFM calcs for you (you do need to input the diffuser/grate area or the area you are trying to measure airflow) 4-Beaufort bar display is nice (I don’t care about this measure but was nice to have) 5-appreciate the case that comes with it and makes transporting the device very convenient 6-decent price Cons: 1-almost damaged my fingers trying to open the battery case 2a-instruction is extremely poor. Full of typo and grammar issues. Not clear at all. Still trying to figure out how to store data and read the stored values 2b- tried looking for their website but failed to find any (should have done my DD before but lessons learned). 2c- this makes me question the accuracy of the device since I cannot find any reference of the manufacturer (I have not tested the accuracy of the device simply could not find a valuable reference to the producer and device) 3- I work with CFM unit but every time I switch the settings to read “Velocity/Temp” and want to go back to the “Flow” reading it automatically switches to CMM rather than the user entered CFM settings 4-backlight does not stay on and will shut off after some time (con in my opinion) 5-the USB port of the device is faulty and any small movements to it will ruin your readings and will have to start over again Overall: Make sure this device suites your application. If just for fun and testing your own home and own personal adventure then this may be an excellent choice. If for more serious applications then probably should look into it with more caution.

I am in the HVAC business, and the instrument is typically used for that application, but I bought this one to also use while driving my motorhome, to determine headwinds when driving (for speed vs fuel economy).

machine works as promised of course I haven't used it more than four times so far but it seems to be accurate I've run it against my other testers and it seems to work well

This is a really useful tool, it works well. The only issue I have with it is the light does not stay on after you turn it on. I don't know why they did this that way, it's annoying as hell. They're led lights and won't drain much battery so I don't understand why they designed it to turn off so quickly. Outside of that it's a great product. (high impact plastic, don't drop it.)

Dit is echt een prima gebruiksklare set. Er zit zelfs een batterij bij. Heel handig dat alles in een koffertje geleverd wordt. Dan heb je altijd de complete set bij elkaar en raakt er niks kwijt. Het is een degelijk apparaat. Goed display. Gemakkelijk te gebruiken. Er zit een duidelijke handleiding bij.

Ricevuto non funzionante la ventola non è bilanciata

works great

Would not waste your money on this not did not work as should and readings completely off the scale of being right

Helaas heb ik deze maar een paar keer kunnen gebruiken hij is in oktober al stuk gegaan maar toen dacht ik nog dat het aan de batterij lag vandaag wilde ik hem weer gebruiken met splinternieuwe baterijen maar helaas mocht het niet zo zijn. Ik hoop dat ik nog ergens garantie kan claimen. De bouwkwaliteit van het product is in verhouding naar de prijs niet wat je er van zou mogen verwachten
