The 0.02 mm/m precision spirit level with prismatic base is a metrological instrument designed for accurate control of flatness, straightness, and alignment in industrial applications and machine tool geometry verification.

The body is made of painted cast iron, selected for its high dimensional stability and excellent vibration damping properties, ensuring reliable and repeatable measurements over time. The base features a V-shaped prismatic groove, allowing secure positioning on both flat surfaces and cylindrical components such as shafts and guideways.

The instrument is equipped with both longitudinal and transverse spirit vials, enabling multi-axis control and facilitating alignment and adjustment operations. The 0.02 mm/m sensitivity provides an ideal balance between precision and usability, making it suitable for both workshop metrology and installation tasks.

The measurement principle is based on the displacement of the bubble within a calibrated vial, allowing detection of minimal inclination changes relative to a reference plane. This enables precise verification of surface flatness, guide straightness, and mechanical alignment.

This level is widely used in CNC machine installation, geometric inspection, preventive and corrective maintenance, and industrial metrology, making it essential for technicians, maintenance personnel, and quality control operators.

Its robust construction and consistent accuracy make it reliable even in demanding industrial environments.
