Precision spirit level – SAL1000

The precision spirit level is a control instrument designed for checking level and inclination on mechanical references where higher sensitivity is required compared to a standard workshop level. In technical applications it is used for checking machine beds, guideways, base plates, tables and machined surfaces, but thanks to its prismatic base it is also suitable for cylindrical components.

This precision spirit level is equipped with a V-grooved prismatic base, a very useful solution when inspections involve not only flat surfaces but also shafts, rollers, tubes and cylindrical components. This feature makes the instrument more versatile than a common spirit level because it allows the same instrument to be used on references with different geometries.

The 0.02 mm/m sensitivity makes it suitable for alignment and leveling inspections where even small deviations must be identified clearly. For this type of inspection, it is important to use a stable instrument with a clear reading and a base capable of ensuring proper contact with the reference surface being checked.

An important technical feature is the thermally insulated handle. During sensitive inspections, direct hand contact may influence instrument behavior, therefore this solution helps reduce heat transfer from the operator’s hand and improves correct use during inspections. The bubble protection cover is another practical feature because it helps protect the reading area during normal workshop handling and movement.

From an application point of view, this type of precision spirit level is particularly useful during machine installation and alignment, verification of mechanical structures, inspection of guideways and checking cylindrical surfaces that must be positioned correctly either level or with a controlled inclination. For this reason, it is a practical instrument both in workshops and in quality control departments.

The instrument is available in 150, 200 and 300 mm lengths, all with the same 0.02 mm/m sensitivity, allowing the most suitable version to be selected according to the available space and the surface to be inspected. Shorter versions are practical in confined areas or on smaller components, while longer versions provide wider support on larger references.

In summary, this precision spirit level is a reliable solution for checking level and inclination on both flat and cylindrical references, with accurate reading and a construction designed for professional workshop use.
