**天秤工作安全指引 : 風速超過每小時62公里，立即停止吊秤工作。
The air flow meter enables wind speed measurements up to 105 km/h and is versatile in use. The air flow meter is equipped with an integrated temperature sensor that measures both Celsius and Fahrenheit. The functions for maximum and average wind speed enable effective monitoring of the measurement results.
The air flow meter enables measurements in various units such as m/s, km/h, kn and mph and also has a Beaufort scale for quick assessment of the wind force. The easy-to-read LCD display with backlighting ensures optimum readability in all lighting conditions. The automatic switch-off function after 15 minutes of inactivity extends the battery life to at least approx. 30 hours. The air flow meter is supplied with a practical carrying case for travelling.
