Vacuum Manometer Gauge -1 Bar with Glycerin Filled

Vacuum Manometer Gauge -1 Bar with Glycerin Filled is a specific type of pressure measurement device used to measure vacuum pressure. Here's what the different components of this term mean:

1. Vacuum Manometer Gauge: This part of the description specifies that it's a type of manometer. A manometer is a device used to measure the pressure of gases, liquids, or vapors. In this case, it's designed specifically for vacuum pressure, which means it's used to measure pressures below atmospheric pressure.

2. -1 Bar: This indicates the range of pressure that the manometer is capable of measuring. "-1 Bar" means that it can measure pressures ranging from atmospheric pressure (0 Bar) down to 1 Bar below atmospheric pressure. In other words, it can measure both positive and negative pressures, but it's calibrated in bars, where 1 Bar is approximately equal to 1 atmosphere of pressure.

3. Glycerin Filled: The term "Glycerin Filled" means that the gauge has been filled with glycerin, a type of liquid, to dampen the movement of the internal components. Glycerin filling helps protect the gauge from vibrations and pulsations in the measured system, making the readings more stable and prolonging the life of the gauge.

In summary, a "Vacuum Manometer Gauge -1 Bar with Glycerin Filled" is a pressure gauge specifically designed to measure vacuum pressures (pressures below atmospheric pressure) within a range of -1 Bar to 0 Bar. It is filled with glycerin to provide stability in its readings. This type of gauge is commonly used in various industrial and scientific applications to monitor and control vacuum systems.
