Frequently Asked Questions

Q: What is the primary difference between a bar level and a frame level?

A bar level is a linear tool with a V-grooved base designed specifically for cylindrical surfaces and confined spaces. A frame level is rectangular and designed for multi-dimensional flatness checks on large flat planes.

Q: How do I maintain the accuracy of my precision bar level?

Clean the measuring surface thoroughly before use, avoid direct sunlight or extreme heat to prevent liquid expansion, and periodically check the zero position of the vial.

Q: Can this tool be used for non-cylindrical surfaces?

Yes, while the V-groove is optimized for cylinders, the level can still be used for flat surface alignment, although a frame level is recommended for large-scale flat inspections.

Q: What does the 0.02mm/m accuracy specification mean?

It means the tool can detect a tilt as small as 0.02 millimeters over a distance of one meter, providing the extreme precision required for CNC and aerospace engineering.

Q: Is the calibration certificate provided with the purchase?

Yes, every Storaen bar level comes with a traceable calibration certificate confirming compliance with ISO 17025 standards.

Q: How does the cast iron body benefit the measurement process?

The heat-treated cast iron body dampens vibrations from industrial machinery and resists thermal expansion, ensuring the bubble vial remains stable and accurate.
