• 【10" (250mm) & 40" (1000mm) Travel Length】2 Axis LCD DRO & 10" (250mm) & 40" (1000mm) Scales Kit.  This DRO kit is commonly fitted to machines, especially for metal working — lathes, cylindrical grinders, milling machines, surface grinders, boring mills and other machine tools — to allow the operator to work faster and with greater accuracy. Use of DROs is not limited to manually operated machines. CNC machines can usually be switched to manual operation, and in this case a form of DRO is simulated on its control panel. Scales include ​140mm extra length for secure mounting (total length = travel + 140mm).
• 【2 Axis LCD Display】 ​Large LCD Display shows real-time X/Y coordinates with ​1m/s tracking speed. A multifunctional 2-axis LCD digital viewing instrument/digital reading gauge is specially designed for numerical control machines, providing high-precision measurements with a resolution of 0.1 μm for efficient and accurate machining. Characterized with high scanning frequency, quick graphic machining, low measuring error and powerful functions, It has a good capacity of resisting disturbance.
• 【High Precision & Resolution】±1/ 2/ 5/ 6/ 10μm resolution (adjustable). ​5μm grating pitch with TTL signal output for unmatched accuracy. Works with ​5V TTL signals (NPN output) for seamless integration with encoders or scales. ​9-pin connector supports TTL square-wave input (pins: +5V, GND, A, B). 60m/min scanning speed (40ips) for high-speed machining.
• 【Multi-Functionality】 SDM 200+ memory sets, power-off retention, bevel processing, and calculator. Advanced functions--1/2 centering, error compensation, arc/circle drilling, zero setting, tool compensation etc..
• 【Industrial-Grade Durability】 ​IP53/IP64-rated casing with ABS Shell(DRO), or aluminum alloy housing with anti-corrosion chrome plating (TTL glass scales), is dustproof & scratch-resistant. Withstands -10°C to 70°C(14℉ to 158℉) , 90% humidity, andand 600m/s² impact resistance for harsh workshop environments.  
• 【Easy Installation】Includes ​3m shielded signal cable with metal shell for noise immunity. Pre-calibrated scales; zeroing and offset adjustments via intuitive interface. Wide Voltage Compatibility: ​110–240V AC input for global use (built-in voltage regulator). Includes L-shaped dust bar, brackets, screws, and manual
• 【Application】The Multiple function digital readout kit is specially designed for mechanical process. It is suitable for lathe, milling machine, grinder, boring machine, spark tester and more. Milling Machines: Track X/Y/Z coordinates for complex part machining.​Lathes: Monitor spindle position and cutting depth (lathe-specific functions included). ​Grinders/EDM: Measure material removal rates and electrode alignment. ​Drilling/Cutting: Ensure precise hole positioning and linear cuts.​CNC Systems: Simulate manual mode with DRO interface.
