Parallelism Measurement

How it works

For parallelism measurements, the 90-Line is moved sequentially along the laser path to create multiple reference lines, or planes, that are each square to the original laser reference line and parallel to each other. Along each of these individual square reference lines, the Microgage receiver takes a series of readings to see how that surface, shaft, track, or object is positioned relative to the square laser reference beam. The 90-Line is then moved to a new position, creating another square laser line, parallel to the last line, which measures the position of the next track, shaft, or surface.

Comparing your readings for each surface tells you precisely if the surfaces are out of parallel, by how much, and in which direction. By turning the nosepiece of the 90-Line or the 90-Line Square Plane, the laser can be directed upwards or downwards so that parallelism can be checked for items that do not lie in the same plane.
