TB333 Bird guard

The TB333 Bird Guard is a dedicated accessory for TB3 and TB4 tipping bucket rain gauges, designed to prevent contamination and potential blockage of the catch area resulting in poor quality rainfall data.

It is designed as a powder-coated spring steel ring with upward-pointing spikes distributed around the collector rim to discourage birds of all sizes from perching on the gauge. The high-quality materials and robust construction help maintain uniform spike geometry even after exposure to hail impact and harsh outdoor conditions.

Easy and quick to install, the bird guard does not affect the aerodynamic or hydraulic performance of the rain gauge. The simple single-fastener clamping design allows fast and secure installation without the need for drilling or modifying the rain gauge collector, providing a stable, non-invasive mounting solution suitable for long-term outdoor operation.
