We specialise in the volume production of a low cost, high quality precision glass circular vial & bullseye level. These vials have an anodised aluminium body with a precision ground glass lens. These are available in a wide range of standard sizes and sensitivities. We also manufacture custom bullseye level sizes on request to suit a particular application, or to match an existing specification. They are more expensive than the plastic circular vials but have the following advantages:
