DK830S series 30-mm stroke high-precision gauges

On November 30, 2010, Magnescale (President Toru Fujimori) officially launches the DK830S series of slim-design high-precision digital gauges with 8 mm diameter and 30 mm stroke. In response to demand for a wider range of production line measurements, the measurement range of slim-type gauges has been extended to 30mm. DK830S series gauges can also be used to create high-precision, high-speed network systems in combination with Magnescale Intelligent Network System MG series products.
