These instruments combine the simplicity and robustness of traditional manometers with the accuracy and convenience of digital technology. Digital manometers are often used for calibrating other pressure instruments, measuring pressure drops across filters, or verifying airflow in HVAC systems. When selecting a digital manometer, consider the pressure range, accuracy, resolution, and any additional features such as data logging or connectivity. For example, a digital manometer used in a pharmaceutical cleanroom might require certification for use in such a controlled environment. The instrument’s ability to hold peak readings or perform averaging can also be valuable depending on the specific application. Some digital manometers also offer multiple unit options, allowing users to switch between pressure units like pascal, bar, or psi as needed.
