The Level that thinks it's an Alignment Telescope
![]() An engine frame alignment where the bearing centerline must be evaluated for straightness as well as level. Many rotating machine components have these combined alignment requirements. |

The reticle's filar/bifilar pattern makes for easy use with our optical tooling scales, or during collimation and autocollimation procedures. The horizontal axis pivots directly over the vertical axis, making the change in plane height less than 0.0001" for tilts up to 5 arc minutes either above or below horizontal. This important feature eliminates the need to perform the time-consuming precision plumbing procedure for leveling projects. All 545 models use high quality base components and leveling vials similar in design to our model 76-RH transit, allowing this instrument to sweep precise planes. For rough leveling, the unit has a circular level vial mounted on the base.
Our extreme attention to engineering details means that you can take measurements with accuracies that are difficult to achieve by conventional mechanical methods. Read more about our levels for additional specific information on their many features and uses.
