Microgage PRO: flatness.

Flatness & Planar Measurement

A precision rotating base defines a flat plane of laser light for measuring surface flatness. A digital receiver provides precise surface profile.




How it works

Microgage PRO: flatness illustration.

The laser transmitter is placed onto a precision rotating base called the Leveler which allows the laser to swing through a full circle and define a flat, precise plane of laser light. This plane of light is flat to within 0.001 inch over a 24 foot diameter area. The Microgage receiver is then moved to various locations around this work area and the laser is aimed to the receiver to make a height or profile measurement at that location.

The leveler can be adjusted with three precision adjustment screws and leveled if needed. This is a very versatile part of any laser measuring system.

What our customers say

We did have a chance to use it on a cooling tower torque assembly for straight line and flatness assessments. Your product was very easy to set up and within an hour we had learned the systems and taken readings.
