Micro Process Controls

Universal Stainless Steel Bourdon Type Gauge: Many applications require pressure gauges, which must remain fully functional under extreme operating condition such as aggressive fluids under pressure or aggressive environments. In this case the materials used for the pressure gauges components must be selected with particular care.

Micro high quality pressure gauges are built with stainless, chrome- nickel steels (i.e. S.S.316 or better). They can be used under all operational conditions, practically without limitations. Their concept combines sturdy design and high measuring accuracy.

• The McLeod gauge is a scientific instrument used to measure very low Pressure, down to 10^-6 mbar.
• The McLeod gauge is used to measure vacuum by measuring the height of a column of mercury supported by the gas whose pressure is to be measured, when this gas is trapped and compressed into a capillary tube
