The ND 120 Quadra-Chek metrology digital readout (DRO) from Heidenhain is designed for manual measuring machines such as optical comparators and measuring microscopes. It has the capability to measure and tolerance points, lines, circles, distances and angles, and it supports two to three axes. The third axis can switch between linear and rotary.
The DRO includes a monochrome flat-panel screen for displayed values, measured features and graphical displays. A diecast aluminum enclosure makes the ND 120 well-suited for harsh factory floor environments where production control takes place, the company says. The system features a combination of defined function keys and context-dependent soft keys, and the user-friendly GUI follows previous Quadra-Chek software. It is capable of direct USB communication with a computer, enabling easy storage of data and convenient interfacing.
