GM8909 digital anemometer is carefully designed with "handle lever retractable", no wind direction requirements, telescopic lever can be long or short, to achieve accurate measurement, stable performance, safe and reliable, with low power consumption and other advantages.
Digital Anemometer possesses the following features:
1. Measurement of wind velocity, temperature and flow
2. Selection among max wind speed/min wind speed/average wind speed/current wind speed.
3. Temperature unit selection between ℃ !
4.Inlet area set
5. Selection speed unit among M/S,KM/H,FT/MIN, KNOTS and MPH
6. Reading hold
7. LCD backlight
8. Manual/automatic turning off
9. Beaufort scale
10. Wind chill alert
11. Retractable drag rod
12. Low battery indication
