BTMETER BT-846A Pro HVAC Anemometer Measures Wind Speed Wind Flow Wind Temperature CFM Air Flow Velocity Meter with Backlight MAX MIN AVG
Nice sturdy hard case for storage.
Works well can Choose unit of measurement in metric or standard and also knots like that it has cord so you can read the screen while taking a reading, great for HVAC techs that do testing and balancing. Will also read temp. In either F or C. Also great for construction workers that need to have a wind reading before using equipment such as swing stages and lifts. Has a backlight for darker situations and night readings

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.

The quality of the tool is well a made solid construction very rigid when holding not flimsy at all. The lcd is very clear and the led backlight makes read data in low light even easier. I used this to test out the cfm of a few greenhouses that i wired up automation in and this really helped me get the placement of fans correctly. Overall great tool very easy to understand how to use after reading the instructions for abit. This is a must have tool for testing airflow. Very nice addition to my collection of data tools.

Device looks great but: Battery door can not be closed correctly when battery is inserted due to battery-clip is too high when attached to battery. Tried it many ways but batterylid can never close complete. When powered on the backlight flashes less than halve a second and when backlight is turned on with the lightbutton it's on for max. 5 seconds no matter if your pressing buttons or measuring it goes out after 5 seconds. You can press the light button again but 5 seconds is too short for easy usage. When temperature is set to Celsius and device is switched off it sometimes comes back with fahrenheit when turned on. But setup of device with a backlight of 5 seconds is only possible with a flashlight.... After 1 hour of testing frustration is enough for me to make the decision to return the device. In my opinion the developers have no clue how to build a good userinterface.
