A digital pressure gauge is an electronic device used to measure the pressure of gases or liquids. It displays the pressure reading on a digital screen, making it easy to read and interpret. These gauges are commonly used in various industries, including automotive, HVAC, and manufacturing, to ensure systems operate within safe pressure limits. Unlike traditional analog gauges, digital pressure gauges often provide more accurate readings and can include features like data logging and alarms. They can be powered by batteries or connected to a power source, and many models are designed to withstand harsh environments, ensuring durability and reliability in demanding applications.
