Starrett 709AZ Dial Test Indicator without Attachments, Dovetail Mount, White Dial, 0-15-0 Reading, 1.375" Dial Dia., 0-0.03" Range, 0.0005" Graduation, +/-0.0005" Accuracy

The Starrett dial test indicator without attachments has a Red, black, or white face, and inch measurements. It has a narrow body for use in hard-to-reach areas, and has a choice of red, white, or black dial face for use in a variety of lighting settings. The carbide ball-contact tip reaches into the work piece for accurate measurements of turned, milled, and ground parts, and for tool setting gauges, fixtures, and inspections. The continuous clockwise pointer rotation with automatic reversal helps prevent plus or minus confusion. The ball-bearing lever system with measuring insert swivels through to 210 degrees. The dial has an angled face and three dovetail mounts, and can be mounted horizontally or vertically from the front, top, or back of the indicator. The indicator has a satin chrome finish for durability, and a gear-driven, jewelled movement for accuracy. The contact points are frictionally adjustable and replaceable. This dial test indicator meets or exceeds accuracy and performance requirements of national and international standards, and is traceable to the United States National Institutes of Standards and Technology (NIST). Dial readings with three digits, such as 0-10-0, signify that the indicator has a balanced dial. Dial readings with two digits, such as 0-100, indicate that the dial has a continuous dial. Balanced dials are used to read 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.
