*Response time refers to the t63 time (time to reach 63% of final value after a step input). 
**Wind speed refers to the airflow at the sensor's sensitive element. Under test conditions with ambient wind speeds between 2-10 m/s and perpendicular airflow to the sensor's intake, the internal wind speed at the sensing element is approximately 1 m/s.
