What You Need to Know When Looking for a Digital Pressure Gauge

With all of the options on the internet these days, it can be difficult to figure out what products are right for you and your application. Specifically when it comes to pressure gauges, the choices can be very overwhelming if you don’t know exactly what it is you’re looking for.  If you are considering a digital pressure gauge but don’t know what information is beneficial in knowing before you make your purchase, you’ve come to the right place. We are going to break it down for you on what you need to know so you can make the best choice for your application.

First, ask yourself why you want a digital pressure gauge:

  • Is it because you want a higher accuracy for testing?
  • Is it because you want a point of reference?
  • Is it because you want durability?

We suggest you ask yourself these questions because the answer you choose will help determine which gauge is right for your application. Let’s take a deeper dive into what these qualities really entail:

Higher Accuracy

Digital gauges are typically higher in accuracy than mechanical analog gauges. They range from 1.0% accuracy down to 0.05% in most cases and the better the accuracy, the higher the price.  Ultra high accuracy gauges (usually between 0.10%-0.05%) are reserved specifically for testing applications and come with numerous features.

Point of Reference

One clear benefit in using a digital gauge over a mechanical gauge is that the digital gauge is much easier to read.  You can also drop your fears of a mis-reading because the digital reading is clear as day and often times the gauges comes equipped with a back light for added visibility. Depending on the options you want, there are various price points and types of digital gauges you can use. We recommend checking out SSI Technologies’ MG-9V, MG1-9V, or the MGA-9V series gauges.


Digital gauges are typically much more durable than mechanical gauges because they’re electronic and don’t have moving parts.  With that, it is much more difficult for them to fall out of calibration over time.  Certain digital gauges are meant to be carried around for testing and are made more robust, so depending on your application, this could be a huge cost savings in the end not needing to replace the gauges overtime.
