If you're in the market for a great pressure gauge, you need to work with a high quality manufacturer that you can trust.

There are many different kinds of pressure gauges, and they are applied in all kinds of contexts.

Air pressure gauges measure pneumatic pressure in any air-operated equipment and can feature analogue or digital displays, as can most gauge varieties.

Differential pressure gauges are instruments that measure the difference in pressure of a gas or liquid between two points. This eliminates the need for an operator or computer system to watch two gauges and perform the math. Differential pressure gauges are fast and efficient and immediately and constantly display information in one location.

Water pressure gauges monitor the pressure of any water-based system. These type pressure gauges are commonly attached to tanks that require monitoring of the liquid within.

Fuel pressure gauges are instruments that specify the pressure of the fuel supply to the intake manifold in a combustion engine vehicle. This display represents how much gas is left in the tank.

Oil pressure gauges are tools that measure the pressure of oil circulating in any lubricating system. Maintaining the correct amount of oil in a vehicle can increase its longevity; the same is true in machinery.

Gas pressure gauges measure and display the pressure of a gas. They are widely used by manufacturing plants or industrial companies where it is important to monitor any changes in pressure in order to control the rate of flow of gases such as propane or natural gas. They are used to measure very high pressures as well as low pressures.

Vacuum gauges are instruments used to measure and display sub-atmospheric or vacuum pressures within a system or vessel. Vacuums are frequently used to create cold temperatures for certain processes.

Temperature gauges take measurements in a variety of materials including air, oil and water. They are used in the home purposes as well as in scientific processes.

Digital pressure gauges are attached to an instrument that measures the pressure of a gas or liquid and gives numerical readings. They display readings in digital, rather than analog, form. Digital readouts are typically easier to read and provide greater accuracy. They usually run on batteries and are available on most kinds of pressure gauges.

High pressure gauges are instruments that measure and display the pressure of gases and liquids moving at high velocities. When the temperature rises or more gas and liquid is added to the container, the pressure increases even more. High pressure gauges are manufactured for industrial and manufacturing applications, mainly for high pressure hydraulic technology including water cutting machines, hydroblasting pumps and hydro-demolition. Some high pressure gauges are specifically designed for use in high purity semiconductor gas and liquid applications; they feature pressure ranges from less than 15 PSI to as high as 10,000 PSI.

Low pressure gauges generally measure pressures of 10 to 15 PSI. Gauges designed for low pressure are extremely sensitive and accurate out of necessity; many processes depend on the correct pressure to function properly and safely.

Gauges are used in environments where the pressure tends to fluctuate frequently and so requires constant monitoring.

Absolute pressure gauges measure any pressure above zero pressure. It is impossible to create a perfect vacuum artificially, and no perfect vacuums exist on earth or anywhere in space. Absolute pressure gauges measure pressures on a scale that begins with zero, though a pressure of zero is impossible to achieve.

Air pressure gauges measure the air pressure of pneumatic equipment.

Ambient gauges, also called "sea level gauges," are the most commonly used gauge. They are used in meteorology. Ambient gauges are preset to read zero pressure at standard atmospheric pressure (~14.7 psi).

Combination gauges measure both pressure and vacuum.

Commercial gauges, also referred to as "general purpose gauges" or "equipment gauges," are low-cost measuring instruments designed for applications that do not have severe conditions. Commercial gauges may be ruggedly constructed but are not typically economical to repair.

Fuel pressure gauges are instruments that indicate the pressure of the fuel supply to the intake manifold in a combustion engine.

Gas pressure gauges are instruments designed to measure and display the pressure of a gas.

High pressure gauges are instruments that measure and display the pressure of gases and liquids moving at high velocities, up to 10,000 PSI, a very high pressure when compared to the atmospheric pressure of ~14.7 PSI.

Industrial gauges have heavy-duty sensing elements and case designs and higher accuracy requirements than general purpose gauges. They are built for extended life and are designed for use in harsh environments.

Liquid filled gauges can be filled with various fluids, such as silicone oil, mineral oil and glycerin. The liquid fill provides protection to internal components of the gauge in severe environments in which the gauge may encounter excessive vibration and pulsation.

Liquid filled gauges are utilized in nitrous systems on nitrous bottles or solenoids.

Low pressure gauges are designed to accurately measure pressures less than 15 PSI using a capsule sensing element.

Oil pressure gauges are instruments that measure and display the pressure of the oil in an enclosure, particularly oil circulating in a lubricating system.

Precision and test gauges are extremely sensitive and highly accurate instruments that are used in applications that demand precision and consistent results, such as instrument shops, gauge repair and calibration shops and testing laboratories.

Process gauges are made from corrosion resistant material to meet the demanding heavy-duty operating and construction requirements of the chemical and petroleum industries. Process gauges are also designed to fulfill the exacting accuracy and service life needs of a variety of process applications.

Retard gauges have a scale that is compressed at either one or both of its ends.

Temperature gauges are instruments that indicate the temperature of an item or substance being measured. The results may be displayed through an analog dial or digital readout.

Vacuum gauges indicate negative atmospheric pressure or the degree of rarefaction below atmospheric pressure.

Water pressure gauges are designed to determine and monitor the pressure of any system that uses water.
