Davis Black Max or Telo-Cat Spare Vane

The Davis Black Max or Telo-Cat Spare Vane (MPN 1452) is a replacement vane assembly designed for Davis Instruments' anemometer instruments, specifically the Black Max and Telo-Cat weather monitoring systems. If you're maintaining precision weather station equipment or upgrading your automotive shop's environmental monitoring setup, this spare vane ensures accurate wind speed readings over the long term. As a mechanical professional, you understand that worn or damaged sensor components compromise data integrity—this replacement vane restores measurement accuracy without requiring a complete instrument replacement.

Constructed from tough high-impact plastic, this vane features visible trim markings that facilitate proper alignment and installation. The durable polymer construction withstands environmental exposure, temperature fluctuations, and the repetitive rotation cycles inherent to anemometer operation. At just 0.1 lbs and measuring 2 x 1 x 8 inches, the vane is lightweight yet rigid enough to maintain consistent aerodynamic performance. The design philosophy prioritizes longevity—high-impact plastics used in Davis instruments resist UV degradation and impact damage from weather exposure or accidental contact, critical for equipment deployed outdoors or in shop environments where reliability matters.

Technicians and facility managers benefit most from stocking this spare vane as routine maintenance inventory, ensuring minimal downtime when sensor components require rotation. Installation is straightforward—the visible trim markings guide correct orientation, making replacement accessible even for non-specialists. This spare vane is compatible with both Black Max and Telo-Cat anemometer models, making it a versatile addition to your parts inventory. Whether you're supporting a professional automotive facility's climate control documentation or maintaining dedicated weather monitoring for engine testing and diagnostics, having this replacement on hand prevents extended outages.
