Digital Anemometer Wind Speed Meter, 6-in-1 Wind Gauge for Velocity/Temperature/Relative Humidity, Auto-Off with Data Hold, LCD Backlight, for Shooting, Sailing

Thought it was not working but after I unplugged the battery cable and reattached it the unit turned on. Be aware that you must hold your finger on the power switch for more than a few seconds before it turns on. A quick press will not work. After it started, I set the units and this is incredibly sensitive to air flow. Bare wisp of air will spin the cups. The touch screen works very well. This was an awesome purchase and a great price.

I just needed this unit to provide general CFM reading which it does quite well. It also can perform numerous other measurements which I have not pursued. It appears well made and is fairly simple to operate.

Very nice device. The speed indicator is extremely sensitive and can measure less than 1 mph. Wind speed settings can be displayed in mph, kph, and knots for boaters. Backlight works very well providing a clear display.

Grandson likes this. He has an interest in weather. Item seemed sturdy and reliable, re-out was good.

Worked as advertised.

Arrived on time. Works as advertised. A price you can easily afford.

I tested this anemometer to several CFM-rated fans that I have, and this meter was mostly accurate. It measured on the higher end when compared to a separate vane-type anemometer. It can do all the standard units and also includes temperature as well. There is a hole in the bottom to attach it to a tripod for higher accuracy readings. It has various back-light options and seems to have a generous after-sales guarantee. This specific anemometer is the 'wind-cup' type of anemometer, so it has cups in a protective cage that can read the wind's speed from any direction. This unit could use a way to be rechargeable so-as to avoid using batteries. Additionally, it could really use a case as even though the cups are in a cage, it would still be easy to damage them. Great portable unit.

This things ready to be used within a minute. Intuitive controls/functions similar to most handheld testing equipment. Such as the hold key and unit key. From testing with other equipment it appears to be accurate, but as I do not possess a certified and calibrated anemometer I can not rate it 5/5 for accuracy, but this is not a fault of the device. The cage around the wind cups appears to be sturdy and should prevent any damage to the wind cups themselves. Overall this will be a handy tool to have!
