ViGauge is a precision dial indicator with a contact arm that bridges the authenticity of traditional gauges with the accuracy of nanometer-scale technology. Like classic dial indicators, it picks up displacement via a probe or roller in contact with the part surface, but inside its familiar, rugged body lies a fundamental revolution: the old magnetic system has been completely eliminated and replaced with an optical/laser measurement system. The movement of the contact arm shifts a tiny optical element, and this displacement is detected by a sensor with an extraordinary resolution of 50 nanometers—resulting in an instrument that feels like a standard dial indicator yet delivers far greater accuracy and repeatability than any conventional model. With 50‑nm tracking precision, ViGauge displays readings down to four decimal places in millimeters (0.0001 mm), while its standard form factor and compatibility with common magnetic bases ensure a familiar, professional user experience. A dual display shows the measured value both on the device’s bright screen and, in real time, via USB to dedicated PC software; essential control keys—zero setting, mm/inch switching, and professional software for continuous data logging, displacement‑time charting, statistical analysis, and output in standard formats—make operation seamless and efficient. ViGauge’s applications span from quality control of ultra‑precision components in aerospace, medical, and micromachining industries, to tool setting and spindle run‑out checking on CNC machines, metrology and calibration laboratories, semiconductor and electronics manufacturing, structural vibration and displacement monitoring, and even university research in tensile and bending tests—delivering nanometer accuracy and real‑time digital recording across all these fields.
