Digital and Auto Level
Capital Surveying Supplies has a wide selection of surveyor's levels available in both digital and optical.
Automatic Levels
An automatic level instrument, or builder's auto level includes an internal compensator mechanism (a swinging prism) that, when set close to level, automatically removes any remaining variation. This reduces the need to set the instrument base truly level, as with a dumpy level. Self-levelling instruments are the preferred instrument on building sites, construction, and during surveying due to ease of use and rapid setup time.
Digital Surveying Levels
A digital electronic level reads a bar-coded staff using electronic laser methods. The height of the staff where the level beam crosses the staff is shown on a digital display. This type of level removes interpolation of graduation by a person, thus removing a source of error and increasing accuracy. It is widely used in surveying and construction to measure height differences and to transfer, measure, and set heights of known objects or marks.
