Davis Black Max or Telo-Cat Spare Vane

The Davis Black Max or Telo-Cat Spare Vane (MPN 1452) is a replacement vane component designed specifically for use with Davis Instruments cup anemometers in weather stations. This vane is crucial for maintaining accurate wind speed measurements, ensuring reliable data collection for environmental monitoring.

Engineered to integrate seamlessly into standard Davis anemometer housings, the vane's lightweight construction—just 0.1 lbs—minimizes rotational inertia, allowing for rapid response to changes in wind speed. With a length of 8 inches and a compact profile of 2 x 1 inches, it is designed for optimal performance in measuring wind speed based on rotation frequency.

Weather station operators and environmental scientists benefit most from keeping spare vanes on hand, as they help prevent downtime and ensure continuous, accurate readings. The precision-molded design guarantees balanced rotation and minimal drag, making it an essential component for anyone relying on accurate airflow data.
