Our precision sight levels are excellent for quickly and easily establishing a gravity-level reference plane, and then measuring deviations of any point from that plane. Use them to evaluate the orientation of tables, ways, sole plates, rollers, shafts, or just about anything else. Take a look at the 545-160, which is a multipurpose instrument, incorporating many of the capabilities of an alignment telescope having dual-axis micrometers. Like most of our instruments, our levels may be checked in the field for proper adjustment. That's one of the beautiful things about Optical Tooling!
