Thermal velocity probe built temperature and humidity sensors, simultaneous measurement of temperature and humidity handheld anemometer for measuring the ventilating ducts. 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 anemometer probe GM8901 * Measurement items: Speed ??/ air temperature * Measuring range: ---- Winds : 0 to 45 m / sec, 0 to 140 km / h, 0 to 8800 ft / min abacus wind anemometer, 0 to 88 nm / h, 0 to 100 miles / hour (accuracy: ± 3%) - - air temperature: 0 ~ 45oC, 32 ~ 113oF (Accuracy: ± 2oC) * Resolution: 0.2oC intelligent pressure anemometer, 0.1m / s * Wind speed unit: m / s, Ft / min, Knots anemometer, 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) wind speed measurement units Range Resolution Accuracy m / s 0.1 ~ 25.0 0.01 ± (5% + 1d) reading or ± (1% + 1d) full scale km / h 0.3 ~ 90.0 0.1 ft / min 20 ~ 4925 1 MPH 0.2 ~ 55.8 0.1 knots 0.2 ~ 48.5 0.1 air temperature measurement Measuring range 0 ~ 50 ℃ Resolution 0.1 Accuracy ± 1 ℃ Air Flow Measurement Unit Range Resolution CFM 0-99999ft3 / min 0.001 ~ 100 CMM 0-99999m3 / min 0.001 to 100 Specifications Display Dual display with backlight large screen sampling rate of about .0.8 seconds Operating temperature 0 ~ 50 ℃ Operating humidity <80% RH Power Supply 9V battery Dimensions 210 × 75 × 50 mm Weight 280 g Handheld anemometer | Jinke instrument Instrumentation (Online) | anemometer provided by Qingdao Branch of the Instrument Co., Ltd.
