Glass tubular bubble level vials are also called glass tubular level vials, which are widely used in various kinds of levels or instruments to see whether a surface is horizontal or vertical. There are many kind of bubble level vials of different shapes and materials. There are the high-precision glass tubular bubble level vials, general-precision glass tubular bubble level vials and common glass tubular bubble level vials.
High-precision glass tubular bubble level vials are made from glass of high strength and hardness. Its sensitivity is from 2" per 2 mm to 20" per 2 mm. According to it's high precision, the glass tubular bubble level vials is used in frame leveler, bar level meter, imaging level meter, which demand high accuracy. Common glass tubular bubble level vials are usually used in level instruments and laser instruments which have a lower requirement to precision.
