The best height gauge is important and a very helpful tool for machinists. It is used for measuring the height of small parts, comparing the heights, and marking them. You can use it to measure the difference in height of 2 points as well.
A high spec electronic height gauge is able to carry out various measuring tasks such as center-line distances, internal/external diameters, and step heights. For your information, an electronic height gauge is precise up to .001″ & claims consistency of .0001″.
You can choose the vernier or dial or digital model. The vernier model makes use of vernier scale to provide the measurement reading, while the digital one displays the reading on an LCD screen. The use of a digital height gauge is surely very intuitive and easy. In comparison, you need to learn how to read a vernier scale (like reading a vernier caliper) when using the vernier height gauge. The dial scale is pretty intuitive and straightforward as well.
A height gauge measures the height from a certain reference, commonly the base itself. Therefore, it requires a flat and level surface to stand on. It should be a carbide surface plate so that you can eliminate any possible error during the measurement.
The main parts of a height gauge include a rigid base, a beam with the main scale, a slider with the display reading (vernier scale or digital LCD), a lock nut, a measuring and scribing stylus, a stylus clam, and some fine adjustment screws. The typical measuring range of height gauges is about 6″ but you can find the longer ones.
It comes with a carbide scribing stylus that can mark the height of that object. In some situations, you can clamp a dial test indicator to the height gauge for measurements of squareness, flatness, straightness, roundness, etc.

What Is a Height Gauge?
A digital height gauge uses high-quality, hardened stainless steel as the material. It consists of a solid cast iron base that is robust to ensure its rigidity and stability.
Then, there’s a beam that extends from the base up including a printed scale in imperial & metric formats.
Usually, imperial digital scale ranges from 0 – 12” whereas the metric scale ranges from 0 – 300 mm. Even more, they can measure up to 80”.
Generally, an electronic gauging slider is equestrian on the beam. Besides that, it features a few buttons for Power ON/OFF, HOLD, TOL, SET, MM/INCH, ON/OFF/ZERO, and ABS.
In addition, the slider has a carbide scriber tip on the jaw. Furthermore, the slider and the attached scriber are able to slide up/down along the scale. You can also lock both in place.
Then, use a fine-tune thumb-wheel to make the final adjustments and lock it in place with a second locking screw.
You can also find a port of data output where you can send the data to a printer or computer via a special cable.
Things To Consider Before Buying A Height Gauge
When it comes to choosing the best height gauge for yourself, there are some really important features that you need to consider before buying.
1. Type
You will find two main types of height gauges, i.e., the digital ones that come with an LCD to display the readings and the analog ones which you can use to manually take all the readings. If you are someone who needs a tool that is more convenient and gives you very quick results, then the digital ones are a good choice. You will also see featured electronic height gauges that offer electronically adjustable measuring forces to make the task even easier.
2. Range
The range of height gauges may vary a lot, but generally, it’s between 200 mm to 300 mm. But you will also find height gauges that have ranges less than 100 mm, which might limit you from measuring the height of objects that are slightly bigger. Alternatively, there are height gauges that offer a range up to 500 mm. So, always keep in mind that you have to check the range before buying depending on its use.
3. Graduation
Clear and crisp graduation will surely aid in making your task of taking readings much more manageable. Fine and prominent graduation is also an indicator that the height gauge is premium quality. So, go for the one that has clearer graduations.
4. Accuracy
The quality of your results entirely depends on the accuracy of the height gauge. A minor error can lead to more significant faults. You should always check the accuracy of the gauge before buying it. Make sure that the gauge has an accuracy of at least 0.03 mm.
Conclusion
Measuring the heights of small objects and parts of a machine can be tricky sometimes. And if you do not have the right tool for it, you can end up with much more frustration. That’s why you should choose the right height gauge. We hope that you have now decided which tool suits your job, but if you are still not sure about it, we have some suggestions for you.
As the best overall option, we will recommend the Taytools digital height gauge, as it is a premium height gauge with a rigid base and offers high accuracy. You get a sturdy hardened stainless steel scriber on it. If you want to buy a digital height gauge, then you should get the Mitutoyo 570-312CAL, which comes with a high-contrast digital display and a hand-operated slider.
