Tolerance in normal position is ±0.75 mm/m, upside down ±1.0 mm/m. The liquid in the vial is a low viscosity coloured oil mixture that gives 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.
