Why might a digital manometer be chosen over an analog device?

A digital manometer is preferred over an analog device primarily due to its ability to provide more accurate and easy-to-read measurements. Digital displays eliminate the need for interpreting needle positions on a dial, which can often be a source of error. Instead, digital manometers present readings in numeric form, making it easier for technicians to quickly and accurately assess pressure levels.

Furthermore, many digital manometers offer additional features such as data logging, higher resolution, and the ability to measure changes in pressure with greater precision. These advantages enhance a technician's ability to diagnose HVAC systems effectively, improving overall work efficiency and accuracy.

The other options do not depict the advantages associated with a digital manometer. Digital devices are generally lighter and more convenient to use than analog devices. They typically require fewer manual adjustments due to their automated functions. While production costs can vary, digital manometers usually incorporate advanced technology that can imply higher production costs when compared to simpler analog models.
