Wind Speed Meter with LCD Backlight Display Handheld Windmeter

Wind Speed Meter with LCD Backlight Display Handheld Windmeter Our Wind Speed Meter has a small fan in the head, when wind blows, it can test the speed and rotate. It is very easy to read: Large LCD Display with Back-light. Professional measuring instrument with large screen LCD display and back-light, easy to read data in dark environment. FEATURES: Professional to measure air velocity and air temperature accurately. This meter displays wind speed in 5 parameters (m/s- km/h- ft/min- knots & mph) and temperature is switchable between °C and °F. It also provides Current- Maximum- and Average speed measurement and Wind Chill indication. This anemometer is a professional tool for windsurfing, sailing and kite flying. You can also use it for industrial and home purposes such as measuring speed and temperature of CPU computer fans, air-conditioners, airflow over the roof or walls.   Specifications: Range: 0 - 30m/s, 0 - 90km/h, 0 - 58 60ft/min, 0 - 65mph, 0 - 55Knots.
