Application
Digital universal length measurer is a kind of length measuring instrument which is used in absolute and comparative measurement. It is mainly used in metal-processing industry, especially those measuring rooms or inspection stations of machinery industry and others industrial fields, such as tool-measure and instruments manufacturing.
Features:
1. High quality cast-iron base support, it has a good stability after long-term natural seasoning.
2. Optimization design, make sure the structure with high performance and precision.
3. Various kinds of accessories are provided, so it has good universal performance.
4. It is equipped with optical grating measuring system, the measuring result is displayed in number visually.
5. The illumination system of optical grating adopts infrared illuminator which is low voltage and current, small volume and long life.
6. It uses Abbe's principle and high precision measuring system, so it has a high measuring precision.
