Vacuum gauge (control manometer) in robust design with red/green range. Suitable for visual control of the vacuum in suction devices and systems of all kinds. The green area indicates readiness for operation Vacuum gauges are available in various diameters, with different connections and measuring ranges. The vacuum Meter as a important part of Vacuum lifter ,Vacuum Componets were some part which in Vacuum system , Every diffirenct vacuum Component play diffierent function.For example ,the Vacuum pumb or Vacuum Blower is the power motor to Crate vacuum, and what's the vacuum Pressure they can work, Peple alway use vacuum Gauge to inspect the vacuum degree .We need to tell you Whatever the Vacuum Pumb good , there is no 100% degree Vacuum in the earth .If you want to design a machine with Vacuum power machine , except need a good vacuum Pumb as power ,also need Vacuum thr…
