High-vacuum gauges are instruments used to measure and control the amount of vacuum—a space, or an enclosed space, with very little or no air present—in a particular environment. High-vacuum gauges enable users to measure low-pressure levels, such as those found in deep space, in order to create and maintain a perfect vacuum.

High-vacuum gauges are typically used in a variety of industries and applications, such as electronics, pharmaceuticals, medical, aerospace, and semiconductor manufacturing. The gauges measure low-pressure levels by detecting the pressure differential between two points. The gauge is equipped with a sensor tube, which is placed in the area of interest, and a reference tube, which is connected to the atmosphere. The two tubes are connected to a gauge, and the pressure difference is measured against a scale, usually in the form of a dial or digital readout.

High-vacuum gauges are used to measure a wide range of pressures, ranging from atmospheres below 1 mbar to atmospheres below 1 x 10-7 mbar. In some cases, the gauges are also calibrated to measure negative pressures, such as vacuum pumps.

In addition to measuring vacuum pressures, high-vacuum gauges can be used to control the amount of vacuum in a particular environment. By using additional components, such as sensors and controllers, the gauges can be used to open or close valves, operate pumps, or adjust the pressure in order to achieve the desired vacuum level.

High-vacuum gauges are essential tools for researchers, engineers, and technicians working in a variety of industries where vacuum is required for a variety of applications or operations. They enable users to efficiently measure and control the amount of vacuum in an environment, allowing them to better understand and manipulate the environment.
