The dual axis micrometer allows you to measure deviations from the line of sight in both the horizontal and vertical directions simultaneously. These models provide a means of easily combining two types of measurements – level and straightness – in one instrument. This is beneficial for applications such as bore alignments for drive systems, turbine alignments, gearboxes, extruders, engine bearing lands and laboratory optical paths.
