A pressure gauge is an instrument designed for measuring air, gas, or liquid pressure in various systems and applications. It typically features a dial, with markings indicating the range of pressures it can measure, and a pointer that moves to show the current pressure level. The gauge may be calibrated to display readings in different units such as pounds per square inch (psi), kilopascals (kPa), or bars, depending on user requirements.
