Name Winds Recorder Model JL-22 Technical parameters: Instrument Size: 158 × 90 × 45mm range:. 0m / s ~ 60m / s wind range: 0 to 12 Accuracy: Wind speed ± 1m / s resolution. : wind speed 0.1m / s recording capacity:> 10,000 recording interval: 1 minute to 24 hours adjustable work environment:. -20 ℃ ~ 80 ℃ wind limit alarm:. 0.0m / s ~ 25.5m / s arbitrarily set . (TTL two-way signal output) Power supply voltage: 5v ~ 12v Power consumption: Maximum operating current <5mA (no external control output) power supply: Day six AA batteries or 220V AC (optional power adapter) Communication Interface: USB interface for data presented, complimentary PC software functions and features: This machine compact and beautiful, large-screen LCD, Chinese operation menu, simple operation, reliable performance, recording interval from 1 minute are available upon request be set to 24 hours. (However, due to the limited memory space can be set at any time after viewing stored information to determine at set intervals can be stored for how long). Whole track record of wind speed data, records a long time, data acquisition, recording in one and has historical data is automatically stored after power protection function, effectively storing the collected information. Small machine power, AC and DC, you can use the power adapter or battery-powered (in this case need to turn off the buzzer and other external output). Powerful software, data viewing, easy to operate, reliable performance. Can always import the data logger to your computer, and can be stored as EXCEL spreadsheet file. Powerful real-time monitoring capabilities, real-time monitoring interval can be adjusted as needed. Scope: Widely used in hydrological stations, environmental protection, agriculture, forestry, boating and other industries to provide the most original recording wind speed data distribution products: wind speed sensor (see page 30 of this manual)
