Metrology Base & Platform Levelling

High-precision work platforms & metrology base levelling

A granite surface plate, an optical table or a precision assembly platform is only flat and square if it is level — and it drifts as foundations settle and temperatures move through the day. The GDS610 reads platform attitude to 0.001° with 0.004° repeatability on three magnetic reference planes, and the GSM8 display terminal puts the number where every operator can see it.

Why platform levelling belongs to a digital inclinometer

Precision work starts on a level reference. A granite plate that is 0.1 mm/m out of level skews every measurement taken on it; an optical table that sags with the afternoon sun walks the laser beam off its mirror. Traditional spirit levels read to a bubble and depend on the operator; the specification for a modern metrology base is written in mm/m and arc-seconds, and it has to be demonstrated — at installation, after relocation, and periodically.

Typical use cases

A level reference you can prove

Granite surface plate verification — the GDS610 on its magnetic base reads plate attitude in mm/m and arc-seconds, catching foundation settlement before it skews the measurements taken on the plate.
Optical table drift watch — periodic 0.001°-resolution checks track the table's attitude through the day's temperature swing, before the beam walks off its mirror.
Precision assembly platform levelling — three magnetic reference planes (base and both sides) let one instrument check every axis of a machine base without fixturing.
Installation, relocation & audit records — data storage and a GSM8 display terminal turn each levelling demonstration into a number everyone can see and file.
