Gauge for General Laboratory and Industrial Use comes with measuring range 1 to 0.001mm of Hg. Microvac Engineers manufactures Gauge for General Laboratory and Industrial Use. Microvac Engineers also manufactures a wide range of Gauge, Vacuum Pump and blowers. Gauge for General Laboratory and Industrial Use is normally positioned with the measuring capillary and scale in horizontal position. For taking measurement, the head is rotated through 900 to bring tube and scale in vertical position .The rotation cause the mercury to move in capillary tube. When mercury in open capillary is levelled at zero mark then system vacuum is measured by height of mercury column in the closed capacity, which is calibrated directly in mbar.
