Tire Pressure Gauges: Digital vs. Analog

A pressure gauge is a simple tool that is used to display liquid or gas pressure. It’s widely used in both industrial and residential settings in nearly every field, but it’s most likely used by everyday Joes to measure the air pressure in tires. Analog pressure gauges are well-known from displaying reliable readings efficiently, but dialog pressure gauges have far surpassed it in popularity. In this guide, we’ll discuss what these types of tire pressure gauges are and what advantages each has to offer.

Digital Tire Pressure Gauge
A digital pressure gauge utilizes pressure transducers to show readings on a digital display. They produce quick, accurate readings based on calibration inputs prior to taking measurements while also working at a consistent level for long periods. They rely on solar energy or a battery to run.

There are several key advantages of using a dialog pressure dial; the first of which is durability. Digital gauges are able to perform reliably in extreme conditions, including heat, cold, and even when subjected to vibrations. Accuracy is also practically guaranteed throughout the entire lifespan of the tool, and recalibrating a digital pressure gauge is done via software rather than manually applying pressure where there’s tons of room for error.

Digital pressure gauges are programmable to your exact needs. For instance, they can show force and torque readings just by pressing a few buttons and cycling through the available library of units of measurement. An analog dial would require you to replace dial entirely.

And of course, we can’t forget to mention just how easy it is to read the digital display. Most digital pressure gauges come with backlit displays to help readers in poorly lit places. Also, it’s a lot more difficult to misread large numbers than it is to read a needle moving back and forth rapidly.

Analog Pressure Gauge
If you’ve ever seen a grandparent taking in pressure measurements before, then you’re most likely already familiar with what an analog pressure gauge is. Essentially, it’s a pressure gauge that uses a needle and dial system to display how much pressure measurements based on the location of the need relative to the numbers surrounding the dial.

As you might be able to imagine, there’s a lot of room for error in this setup. For instance, extreme heat and cold can prevent the needle from swinging freely, and vibrations from heavy machinery only leads to frustration when attempting to read the dial display.

In fact, the only area where an analog gauge “trumps” over digital pressure gauges in price. They’re cheaper than digital models, but the possibility of misreading pressure readouts is significantly higher.

Digital vs. Analog: Which Should I Use to Measure Tire Pressure?
Even though digital pressure gauges have an overwhelming number of advantages compared to their analog ancestors, when attempting to read air pressure from tires, at least in non-professional settings, there differences are minuscule. Unless you plan on opening an automotive workshop in the near future, the “rough” pressure rating readouts in an analog display should be adequate, but the added bonus of a backlit display makes digital pressure gauges more reliable in emergency situations.
