Features and applications

BOL-MF level bubbles are used to control the horizontal positioning of lifting equipment, machines, and devices.

The alignment with respect to the reference plane is reached when the bubble is centered in the middle of the marking lines.

The material used to manufacture the level bubble gives the lens high visibility.

The liquid contained within the bubble is characterised by low surface tension and density optimised for use also on aerial platforms.
