INFURIDER Handheld Anemometer, Anti-dust CFM Meter With Touch Button, Rechargeable Wind Speed Gauge for Air Flow, Chill, Temp Test, Waterproof LCD Backlight

I’m no engineer but I think it works, was having trouble with a sandblast dust collector and wanted to see what the cfm was as opposed to what it claims to have. It helped me get it working as it should. It has a lot of options, I only used the cfm function. Great price for a tool that comes in handy.

Der Anemometer wird benötigt um die Windstärke, Temperatur und Luftfeuchte am Aufstellort eines Teleskopes zu messen. Weitere Anwendungsfälle sind die Messung einer Saugleistung und Trocknung von Teleskopen. Leider kann ich die Verarbeitung nicht bewerten, da ich keinen Vergleich habe, mein Eindruck ist hierzu aber sehr positiv hinsichtlich Verarbeitung und Qualität für diesen Preis.

Did not come with a case as shown in the advertisement.

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.

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.
