SMART SENSOR ST6816 Handheld Digital Anemometer Wind Speed Measurement Measurer Air Velocity Airflow Meter Gauge with LCD Backlight Measuring 0.40ms~30.00ms MaximumMinimumAverage Value Stor

A professional digital anemometer with stable performance, safety and reliability. Features: [Wide Application] It can measure air velocity and air , which can be used in wind energy, meteorology, industry, agriculture, hydrology and water conservancy, environmental protection, highways, airports, etc. [Various Units of Measure] Press the UNIT button to select unit(ms, kmh, milh, ftm, fts, knots) when measuring air velocity; and select unit(CMS, CMM, CFM) when measuring airflow. [Accurate Measurement] Measuring from 0.40ms to 30.00ms; supports beaufort scale from wind 0 to 12. [Practical Function] Press the Data Hold button to freeze the displayed reading; auto power off in 10 minutes without any operation; maximumminimumaverage value mode is enabled. [User Friendly] Measures 7.75*2.67*1.1in and weighs only 4.79oz, featuring compact and lightweight; and LCD backlight ensures clear visibility even in low- area. Note: *Batteries are not included. *Do not touch the fan blade with . *Do not store or operate the instrument in area with high or humidity. *In use, do not let the strong directly shine on the fan, in order to measurement errors. * violent vibration. *Remove the battery before storing the instrument for a long time. *To measure the airflow, the cross-sectional area of the tested air duct be determined and input into the anemometer.
