- Tolerance in normal position is ±0.5 mm/m, upside down ±0.75 mm/m.
- Liquid in the vial is a low viscosity colored oil mixture giving the bubble optimal freedom of movement.
- Highly resistant to ultraviolet light and temperature fluctuations.
- The anti-static properties of the liquid means that the bubble is not affected by static electricity.
