Ds03 scale
Product introduction
The ds03 standard is a nationally produced 0. 3 mm accuracy, a standard, a stable reliable performance, a grade measurement accuracy, an automatic ds03 automatic security level, an built-in microplasm, a measurement system using automatic compensation techniques and built-in encoders and digital circuit processing, and a direct display of microreading on the display screen, reading 0. 01 mm directly, and the ds03 standard deviation of 1 km to and from the scale of 0. 3 mm.
