Overview 

The Autool TR401 Digital Anemometer is a portable, high-precision device designed to measure wind speed and ambient temperature across a wide range of applications. It features a sensitive vane sensor capable of detecting wind speeds from 0 to 30 m/s, with a resolution of 0.1 m/s and an accuracy of ±5% of the reading plus 0.5. In addition to wind speed, it measures temperature from −10 °C to 45 °C (up to 50 °C supported), offering 0.1 °C resolution and ±1 °C accuracy. Its 1.6-inch backlit LCD display supports multiple units—including m/s, mph, km/h, ft/min, knots, °C, and °F—for flexible and readable results in various conditions. The device includes practical features like a data hold function, automatic shut-off after five minutes to conserve battery life, and a low-temperature warning system. It also integrates a Beaufort scale indicator (levels 0–12) for quick wind force classification. Built with a durable IP40-rated ABS plastic housing, the TR401 is powered by three AAA batteries and comes with a three-year warranty and lifetime maintenance support, making it ideal for HVAC testing, outdoor use, wind power assessments, and general weather monitoring.
