DIY aluminium sprit level with unbreakable, highly transparent and durable block vials with a sensitivity of 10 mm/m and a tolerance of ± 0.75 mm/min in normal position (inverted 1.0 mm/m).

The low viscosity vial fluid is a coloured oil mixture giving the bubble the best possible conditions for movement. Resistant to UV light and temperature fluctuations. The bubble is not affected by static electricity as the fluid is anti-static.
