This Dual Function Meter simultaneously measures & displays air speed and temperature of the moving air. Super small in size and light weight but it has wide measurement range. It accurately displays wind speed in m/s, Km/hr, ft/min, knots, mph and temperature in Celsius (°C) or Fahrenheit (°F). It provides current, maximum, and average wind speed measurement plus it indicates wind chill. Also displayed is a Beaufort wind scale bar graph whose reading corresponds to the digital wind speed display. Features: Measure Wind Speed (air velocity) & Temperature simultaneously Choice of readings in meters/second, kM/hour, feet/min, MPH or knots Measuring range 0 to 5860feet/min Max/Average/Current reading function °C/°F Temperature unit selection Large LCD with backlight Manual / Auto power off Wind chill indication With Beaufort scale Low battery Specifications: Measurement units & parameters *****Air Speed/Velocity: m/s, ft/min, knots, km/hr, mph *****Air Temperature: °C & °F AIR VELOCITY Range Resolution Threshold Accuracy m/s (meters per sec) 0 - 30 0.1 0.1 ±5% ft/min (feet per minute) 0 - 5860 19 39 Knots (nautical MPH) 0 - 55 0.2 0.1 km/hr (kilometers per sec) 0 - 90 0.3 0.3 mph (mile per hour) 0 - 65 0.2 0.2 AIR TEMPERATURE Range Resolution Accuracy Celsius -10 ~ 45°C 0.2°C ±2°C Fahrenheit 14 ~ 113°F 0.36°F ±3.6°F Thermometer: NTC Thermometer Operating Temperature: -10~45°C (14~113°F) Operating Humidity: less than or equal to 90%RH Storage Temperature: -40~60°C, -40~140°F About 3mA current consumption Power Supply: 1 x CR2032 3V Battery (included) Size: 104.3 x 57.8 x 19.9mm Weight: 58.9g(include battery) Accessories included: FREE 3V CR2032 Button Battery x 1 FREE Neck Strap/Lanyard Instruction Manual Standard Blister Packaging Anemometer Air Velocity Meter à¤Ã×èͧÇÑ´¤ÇÒÁàÃçÇÅÁ à¤Ã×èͧÇÑ´ÅÁ CFM CMM Meter Flow Meter à¤Ã×èͧÇÑ´»ÃÔÁÒµÃÅÁ »ÃÔÁÒ³ÅÁ CFM/CMM > à¤Ã×èͧÇÑ´¤ÇÒÁàÃçÇÅÁ à¤Ã×èͧÇÑ´¤ÇÒÁàÃçÇÅÁ áÅÐÍسËÀÙÁÔ AN90
