Scarlet WL-21 Wind Data Logger Anemometer
The SCARLET WL-21 Wind Data Logger is an industrial-grade wireless anemometer designed for continuous monitoring and recording of wind speed, wind direction, ambient temperature, and barometric pressure. It consists of a long-range wireless wind sensor and a portable receiver with built-in data logging capability, making it suitable for construction sites, ports, cranes, wind energy projects, offshore platforms, mining operations, meteorological studies, and environmental monitoring. Logged data can be exported to a Windows PC in Excel format for analysis and reporting.

- Displays live, average, and maximum wind speed
- Real-time visual and audible (>80 dB) wind alarm with user-programmable thresholds
- Wind speed measurement range: 0.3 to 50 m/s
- Wind direction measurement: 0–359° with no blind sector
- Supports multiple wind speed units: m/s, km/h, mph, and knots
- Measures ambient temperature from –30°C to +60°C
- Includes Beaufort scale and wind chill display
- IP67-rated wireless sensor for reliable outdoor operation
- Up to 3 years of sensor battery life
- USB interface for data export to Excel (.xls/.xlsx)
- Large backlit LCD with historical trend graphs
- Quick installation using a magnetic mounting bracket or 1/4-inch threaded mount
- Wind tunnel calibrated and compliant with CE and FCC standards.
