The TVP Magnet torpedo spirit level is an impact-resistant spirit level in yellow ABS plastic that withstands temperatures between –15°C and +60°C. It has unbreakable block vials with
extremely high transparency and durability. The vial radius is 150mm, which gives a sensitivity of 13mm/m and a tolerance in normal position ± 1.5mm/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.
