From the very beginning, the company aim was to provide precision craftsmanship and customer satisfaction. As the company grew, it began to design and build equipment, which addressed the specific needs of its customers. This exposure in turn provided the basis for the continuing development of Dorsey Gage...

Ultra High Amplification Group 2 All Dorsey Ultra Amplification Indicators utilize the lever principle of motion. They do not rely on rack and pinion motion. This eliminates the inherent error between the meshing of racks and gears. Features: High amplification movement - graduations as low as .00005". Improves readability and minimizes judgement error. Lever principle of amplification - minimizes effect of spindle sideshake. Linearity and repeatability maintained through millions of cycles. 2.25" Bezel - fits many existing fixtures.
