20" / 2mm

Tube spirit vials with 20″/2 mm sensitivity are used for machine and tool set-up and levelling. This sensitivity group includes borosilicate glass and aluminium products, with lengths across the range from 35 mm to 79 mm. Each product is supplied individually.

What does 20″/2 mm vial sensitivity mean?

It means that a tilt of 20 arcseconds moves the bubble by 2 mm. The double-prime symbol denotes arcseconds. Sensitivity describes angular response, while the length of the vial is a separate physical dimension.

Which materials and colours are available?

Aluminium versions are green, while borosilicate glass versions are clear or green. The group contains two aluminium products and five borosilicate glass products.

Volume discounts and quotes on request are available for larger quantities.
