This handheld anemometer combines wind speed, temperature, wind chill, and battery level readings on a single LCD display. It measures wind speed in five units: meters per second, kilometers per hour, feet per minute, knots, and miles per hour, with temperature selectable in Celsius or Fahrenheit. The device uses 2 temperature sensors and 8 vanes to detect low airflows with high sensitivity, making it suitable for HVAC installation, CFM calculations, and duct vent assessments. Wind speed range covers 0.67 to 67.1 mph with an accuracy of plus or minus 5 percent of readings, while temperature range spans from minus 10 to 45 degrees Celsius or 14 to 113 degrees Fahrenheit, accurate to within 2 degrees Celsius. To conserve battery, the unit features auto power off with an adjustable timer, manual or auto backlight that dims when idle, data hold, and data logging capabilities. A lightweight and compact design allows easy portability for outdoor activities such as sailing, kite flying, climbing, cycling, long range shooting, and drone operations. Bluetooth connectivity enables automatic pairing with smartphones and tablets via a dedicated app, and a 1/4 in. metal hole at the bottom fits a tripod for continuous monitoring. Data can be logged and exported to Excel or text files, making this a practical tool for weather stations, marine use, and precision shooting. Material: Plastic.
