A digital manometer is an electronic device used to measure pressure in various applications, such as HVAC systems, automotive diagnostics, and industrial processes. Unlike traditional analog manometers, which use a liquid column to indicate pressure, digital manometers display readings on a digital screen, providing precise and easy-to-read measurements. These devices can measure both positive and negative pressure, making them versatile tools for technicians and engineers. Many digital manometers also feature additional functions, such as data logging and the ability to connect to computers or smartphones for enhanced analysis and monitoring of pressure changes over time.
