摘要

The length adjusted spirit level (10) comprises a surveyor level (30,31), where housing profile (11) and two telescope profiles (12,13,14,15) are provided in a weighing body (25) of the spirit level. The telescopic profiles are loaded to the housing profile, and form a housing base portion (16) with a longitudinal end of the weighing body. A housing extension portion (17,18) has another longitudinal end of the weighing body. A long edge (26) of the housing profile and a long edge (27,28) of a telescope profile form a measuring level (29) at an object.
