Anemometer GM8901 * Measurement items: Speed ??/ air temperature * Measuring range: ---- wind speed: 0 to 45 m / sec, 0 to 140 km / h anemometer, 0 to 8800 ft / min electronic anemometer, 0 ~ 88 nm / h, 0 to 100 miles / hour (accuracy: ± 3%) ---- air temperature: 0 ~ 45oC, 32 ~ 113oF (Accuracy: ± 2oC) * Resolution: 0.2oC, 0.1m / s * Wind speed unit: m / s portable anemometer, Ft / min, Knots, Km / hr, Mph * oC / oF temperature unit conversion * LED backlit display * Max / Min wind speed measuring * average / current wind speed measurement * Data Hold * Low battery indication * Manual / Auto Power Off (14 minutes without operating automatic shutdown) * Packing: PP box + box * Power: 9V battery a * Size: ---- Host: 145 * 72 * 35 mm ---- Blade: 172 * 65 * 29 mm * Weight: 275 g (with battery) Thermal velocity probe built temperature and humidity sensors, simultaneous measurement of temperature and humidity, ventilation ducts and other applicable measurements. Thus, wind speed, air flow, air humidity and air temperature were measured in the same process. 1, the measurement of the average flow velocity and direction. 2, measuring its spectrum to fluctuating velocity flow. 3, measuring turbulent Reynolds stresses and two speed-related, time correlation. 4, the measurement of wall shear stress (usually placed flush with the wall surface using hot-film probe to carry out the principles and speed similar hotline). 5, to measure the fluid temperature (measured in advance probe resistance curve with fluid temperature, and then you can determine the temperature according to the measured resistance wheeled anemometer probe uses: Merry average speed measurement instrumentation handheld anemometer, measure the average wind speed instrument, mainly used for coal mine average wind speed measurement also suitable for wind speed measurement .GM8901 construction, chemical, textile, food storage, aerodynamic research and other occasions, GM8902 temperature wind speed wind scale portable anemometer anemometer _ _ Branch of the Instrument by the Qingdao Branch of the Instrument Co., Ltd.
