Fowler X-Proof IP54 Shockproof Dial Indicator (52-520-460-0)

The Fowler  X-Proof dial indicator is shockproof and waterproof with an Ingress Protection (IP)-54 rating, has an American Gage Design (AGD) Group 2, 2-1/4″ dial face with a continuous dial, a 0-1″ measuring range, 0.001″ graduations, a revolution counter, and tolerance markers, and is designed to measure surface variations in fractions of an inch. The 0-100 continuous dial with revolution counter has 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 carbide contact point provides durability for surfaces with a hardness rating below that of carbide. The lug back is on a sealed back plate for mounting the indicator at right angles to the stand. Protective O-rings on the safety cap, bezel and rotating dial, and IP-54 rating ensure protection from oil, dust, coolant and water.

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.
