High-precision digital height gauges are widely used for precision measurement in the fields of mold parts, precision automated parts, automotive engine parts, electronic connectors, and aerospace, etc. with high-precision grating sensor and precision guiding device, the gauge has stable accuracy and smooth hand feeling, and there is no hop count on display when measuring quickly. With high-brightness green LED, the display is clear and soft color, preventing operators from vision fatigue when long-time working. The ceramic measuring table is precise and durable.
