The Quadra-Chek Series 200 is a digital readout (DRO) system for precision dimensional measurement and inspection.

It processes signals from the measuring equipment's system to display real-time position data on multiple axes (X, Y, Z, and an optional fourth axis).

It is used in conjunction with coordinate measuring machines, optical comparators, measuring microscopes, and inspection equipment in tool shops.

The QC220-ML15 configuration includes multilingual support and programmable measurement functions, including tolerances and geometric calculations.

It runs embedded firmware to manage the display, keyboard input, and data processing of the measuring system.
