The GDS DIY spirit level is an impact-resistant spirit level in yellow polystyrene plastic that withstands temperatures between 15°C and +60°C. Unbreakable block vials with extremely high transparency and durability. Horizontal magnifying vial with luminous reflector. Easy to clean off cement.

The vial radius is 200mm, which gives a sensitivity of 10mm/m with the tolerance in normal position ± 1.0mm/m. The vial fluid is a low viscosity, coloured oil mixture that gives the bubble the best possible conditions for movement and is resistant to ultraviolet light and temperature fluctuations.

The bubble is not affected by static electricity as the fluid is anti-static.
