WL-21

The Scarlet Tech WL-21 is a high-performance wireless wind speed and direction data logger for industrial applications and long-term environmental monitoring. Some of its standout features are:

  • Ultra-Long wireless range of 500m - It consists of a long-range wireless wind speed and direction sensor (up to 500 meters) and a portable datalogger display.
  • Ability to track multiple measurements on a LCD backlit display - With a large LCD backlit display and user-friendly interface, the WL-21 wind logger can track multiple measurements such as wind speed and direction, wind chill, ambient temperature, barometric pressure, and Beaufort scale and provides live wind speed values in a range of measurement units including m/s, knots, MPH and km/hr. Users also can set wind speed limits so that an audible and visual instant alarm will be triggered when wind speed exceeds the set threshold.
  • Long term data logging of up to 1 year - The WL-21 supports up to 1 year of long-term data logging with a 64MB built-in memory and can export data in excel format to computers by using a micro-USB output.
