Mitutoyo Series 543 ABSOLUTE Digimatic Indicator ID-S. Compact as Series 2 dial indicators. After the initial zero-setting with the ORIGIN button, the repeated absolute positioning is no longer necessary over the entire battery life. Employing the ABSOLUTE linear encoder, the ID-S always displays the spindle "Absolute Position" from the origin at power-on. Also unlimited response speed eliminates over-speed errors. SPC data output.
