VACUUM METER (VACUUM GAUGE) - GLYCERINE MANOMETER 63 mm WITH CONNECTION FROM BOKUKOD SKRAW-MET: [2758]PRESSURE MEASUREMENT RANGE: -1 - 0 BAR Vacuum gauges are designed to measure pressures below atmospheric pressure (vacuum) in closed systems.The vacuum gauge is filled with glycerin inside. The glycerin pressure gauge differs from standard pressure gauges with an interior filled with glycerin, which secures and protects the pointer against vibrations and oscillations. Glycerine also allows you to increase the level of measurement accuracy. It has a plug to equalize the pressure inside the manometer with the atmospheric pressure. Application: The glycerine vacuum gauge is perfect for in hydraulically powered machines and devices.It is widely used in hydraulic systems in agriculture, horticulture, forestry, construction and the broadly understood industry.(REVIEW PHOTO - depending on the delivery, the vacuum gauge may differ visually, but its functionality is identical to that in description.) Technical data: Pressure measurement range: -1 - 0 Bar Outer diameter of the clock: 63 mm Thickness of the clock: 30 mm Connection port thread [BSP]: 1/4' (a special connection is required, available on our other auctions )Operating temperature: -10°C to +50°CMaterial: Steel housing, glass viewfinder
