Oil type protractor with magnets

Advantages:

• Micro-ball bearings for high repeat accuracy
• The pointer rotates in a hydraulic oil for stable, precise and error-eliminating reading
• The differential sub-pointer can be traversed against the annular scale with minimal reading error.
• Has a double ring scale to prevent visual reading errors.
• The transparent temperature-resistant oil can visually strengthen the pointer for a better optical measurement.
• The double rail magnet can attract this protractor on a round tube or a surface of ferrous material.
• An extension line can be inserted in the lower slot for measurement and drawing line for a larger area.
