Leica GDF321 Tribrach
The hysteresis of the Professional 5000 Series tribrachs is guaranteed to a maximum of 1" (0.3 mgon) or better.
The foot screws are maintenance free and ensure a movement that is smooth and free of play, even in the most severe environmental conditions.
The tribrachs in this series are recommended for all tasks that require angle measurements of under 3".
Due to the minimal hysteresis, we recommend use of the Professional 5000 Series for all motorised instruments.
