TS-301 Digital Anemometer, Wind Speed Meter with 2.26-inch Big Backlight LCD Screen, Air Flow Meter for Sailing Surfing Drone Flying RC Plane Golf Shooting HVAC

For starters, I used this to measure home HVAC airflow vs filter to decide which level of filters to use. No filter => 1.14 m/s, MERV 5 => 1.10, MERV 11 => 1.03, MERV 14 => 0.78.

Works very well but does take some time to indicate the correct temperature and humidity. Looks like it should last. Happy with the purchase and so far I would recommend.

Worked well and helped me tune my HVAC to blow cold air to the second floor in the summer. the fan looks a little flimsy, but it did the job for its price.

I like this instrument. It is easy to use and readily displays the significant date. I purchased it primarily to determine changing wind speed but it also works well with temperature and relative humidity displays.The only surprise was the units used for wind velocity. Instead of mph that I am accustomed to it displays this as: mil/hr.

Great little device! It is compact but easy to handle and read. Small price for a lot of information.

I bought this anemometer because it was so highly rated, and the features lends itself to being preferred for Seniors because of it's size, easy to hold, light weight, and DARK EASY TO READ LARGE NUMBERS. The screen can easily be read even in the glaring Arizona sun. I keep mine in my bike basket and use it to keep track of the windspeed I'm up against on my rides. The unit slides in and out of the provided pouch very easily for quick access when needed. I highly recommend it.

I really liked the fact this had temp and RH built in and a nice shaped unit. When I first tested it out it worked as intended. 1 week later I took it to the range and it failed almost completely. It was 80°F out and 29.9°Rh humidity according to the weather app and my buddy’s kestrel. However this was telling me it was 9° F outsideI was forced to abandon it after trying for 20 minutes and returned it for another one. Hopefully the replacement won’t let me down again too….***update is customer service is top notch absolutely awesome. I found the reason for the error was only because the display couldn’t handle showing temp over 99.9 and was actually reading 109.0 but displayed 09.0 as it was in the sun. I let them know about the decimal place display error causing confusion and they forwarded it to their designer to implement the fix.Bottom line is it’s working but was only readable for xx.x° and if you know that you’re good to go… and knowing their customer service is great is a extreme bonus! Can’t wait to see the new update design!!!A second product update… the company was unbelievable to work with… they listened to the issue i pointed out, they implemented it with their engineers and designers and corrected the newest version to read the actual temp over 100.0° .I can’t say enough positive things about this company and this unit.

This review is for the TOPTES 301 Anemometer. I mention this because there are several brands of what appear to be the same model anemometer, just a different brand name and price. This one easily fits into a Flight kit, or in your pocket. It responds quickly to changes in Temp,, Relative humidity and Wind Speed.The only changes I would recommend would be to add a tripod support socket so you can leave it position to constantly monitor wind conditions. I didn't lower my rating because I knew that when I bought it. I just didn't realize that would be a handy feature.One other feature that would be nice to have, or maybe I haven't figured it out yet. There is a Max/Min button for your Temp and RH readings, but it does not work for the wind speed. You pretty much have to remember or write down your windspeed while holding the unit to get your measurement.However, for the money and the size of this unit, I would recommend it for Drone flying as well as other applications where you need to measure airflow and temp.I measured this against other Hygrometers and thermometers and it is fairly accurate and responds to changes faster than other digital and analog thermometers and Hygrometers.No compensation for this review. Purchased about a month ago. Good Prodcut.
