BMI Eurostar levels with patented laser markings and reflection-free readability! The 2% slope markings on horizontal vial are ideal for use with groundworks and setting out the required fall needed for drainage. Laser-marked vials provide measuring accuracy of 0.5 mm/m throughout its service life. BMI spirit levels feature rounded magnification vials which prevent the “double bubble” effect that is found on conventional square vials, which provides the user with increased accuracy. Lightweight Aluminium walls are highly durable and robust for a longer service life and shock-absorbing rubber caps protect the level and maintain accuracy. Available in a range of sizes and both magnetic and non-magnetic variations.
