The Fowler 52-520-199-0 black-face dial indicator with magnetic base and continuous dial has a 0-1" measuring range, 0.001" graduations, a revolution counter, and tolerance markers, and is designed to measure variations in thousandths (0.001"). The American Gage Design (AGD) Group 2 dial has a 2-1/4" continuous dial with a reading of 0-100, a revolution counter, a total measuring range of 0-1" and 0.001" graduations, with each revolution equal to 0.1". An adjustable bezel and dial zeros the reading at any location. Tolerance markers allow operators to observe limits at a glance. The magnetic base has an 85lb. pull and the ability to mount test indicators with a 1/4" post. Fine adjustment knobs allow for making micro-adjustments. The base is 2 x 2-11/32 x 1-13/16 inches (H x W x D) and has a V-shape for mounting on round surfaces. (H is height, the vertical distance from lowest to highest point; W is width, the horiÂzontal distance from left to right; D is depth, the horizontal distance from front to back.)  The set includes a dial indicator, magnetic base, and fitted storage box. Dial readings with three digits, 0-10-0 for example, signify that the indicator has a balanced dial. Dial readings with two digits, 0-100 for example, indicate the dial has a continuous dial. Balanced dials are used for reading the difference from a specific surface reference point. Continuous dials are used for direct readings and usually have a larger measurement range than balanced dials.  Specifications  Dial face type and diameter AGD Group 2, 2-1/4" diameter face Dial type Dial type and reading Continuous 0-100 Range and graduations 0-1" Graduations 0.001" Revolutions Up to 10 revolutions, each revolution equal to 0.10" Contact point construction Carbide contact point with 0.080" diameter Magnetic base pull 85lb.                                       Â�...
