Description
The Mitutoyo 543-691 ID-S112M Digimatic indicator gauge measures to 0.5” (12.77 mm), has an LCD digital readout with resolution of 0.00005” (0.001 mm), and data output to transmit results to a Mitutoyo miniprocessor or computer for statistical process control (SPC). The gauge is accurate to + or – 0.00012” (0.003 mm), and supports a measuring force of 2.0 newtons or less. The unit runs on, and includes, one SR44 battery.
This indicator gauge has an electronic microprocessor that can set a temporary zero position and return to a true zero reading, and switch counting direction. The LCD digital readout can display measurements in inches or metric units. The output port transmits results to a Mitutoyo miniprocessor or computer through an interface cable for SPC (sold separately). The electronics housing has an Ingress Protection 42 (IP42) rating, for protection against objects larger than 1 mm and direct sprays of water at vertical angles to 15 degrees. An electrostatic capacitance linear encoder helps prevent overspeed errors which help ensure repeatable, precise measurement. The gauge’s stem diameter is 3/8”, with threads conforming to #4-48 UNF of the Unified Thread Standard (UTS). The gauge conforms to the American National Standards Institute/American Gage Design (ANSI/AGD) standard.
