Handheld Digital Anemometer, Wind Speed CFM Meter Temperature Gauge with Digital LCD Display, Air Flow Velocity Tester for HVAC Shooting Drone Fishing Surfing, USB Data Upload, Real-Time Sampling

Seems to work okay to measure my hvac air duct flow. The temperature sensor doesn't appear to be accurate though.

Seems to work well at this time. Would recommend the manufacturer use a storage card instead of a mini disc to provide the program. Buyers of this product cannot load the program if their system uses a Microsoft "S".

I fly RC aircraft and it's nice to be able to measure the wind speed to aid in flight safety.

I got this product because I have an amateur interest in meteorology. Perhaps I am not the target audience, and someone with expert knowledge would have an easier time using it. However, I found it somewhat challenging to read, and sort of clunky, with limited buttons to cycle through a lot of measurements. For instance, you can change the units between meters per second, kilometers per hour, miles per hour, feet per minute, feet per second, and knots. The user manual seems dense and difficult to understand; if it more clearly explained the different functions, that would make a world of difference. There also seems to be a language or writing mechanics issue that contributes to the confusion in the manual. The accompanying cable is USB-A to Micro USB, and the product comes with a CD to install PC software and the USB drivers to enable real time data uploading. So the technology--or, at least, the means to access it--is dated. I would say that the CD-ROM is obsolete. I don't have a computer with a USB-A port (the Micro USB end plugs into the device), and definitely not one with a CD-ROM drive. That said, the measurements I tested (temperature, relative humidity, and wind mph) seem accurate.
