1. Overview 

Thank you for purchasing the ennoLogic eA990R anemometer, 
a high quality instrument which measures 8 parameters:

 

 

Wind Speed (mph, m/s, ft/min, knots, km/h) 

 

Wind Chill (°C / °F) 

 

Air Temperature (°C / °F) 

 

Humidity (%) 

 

Heat Index (°C / °F) 

 

Dew Point ((°C / °F) 

 

Barometric Pressure (hPa, mbar, inHg) 

 

Pressure & Relative Altitude (m, ft) 

 

The eA990R anemometer comes with many powerful features 

including the following: 

 

LCD with White Backlight 

 

Beaufort Scale 

 

Maximum, Minimum, and Average Reading Display 

 

Hold Function 

 

Rechargeable Li-Ion battery 

 

Low Battery Indicator 

 

Auto Power Off (with override option) 

 

Calibration Function 

 

CE Certified & RoHS Compliant 

 

Important: 

This meter is accurate at low and mid-range air speeds. 

Consistent use at very high speeds, e.g. from the window of a fast 

moving car will damage the impeller’s bearing and reduce accuracy.
