A digital dial indicator or commonly referred to the digital indicator is the electronic type of dial indicator. When people demand speed, a digital indicator excels it. Instead of calculating the two scales, a digital indicator shows the reading on the screen which lets you quickly know the measurement result. You don’t need to manually read the smaller and the bigger dial scales. You could save time and enjoy it.
Since it’s electronics, dust and water may intrude into the system and then causes interference. Interference means an error that may result in giving a false reading. Therefore, some products come with an IP rating. This rating is important to indicate how resistant a digital indicator against water and dust ingress.
The downside thing about this electronic measuring tool is the battery. When it’s off, you are totally unable to use it. Moreover, you need to consider the type of battery that it uses.
If you are going to purchase the new digital dial indicator, you are at the right stop. You could take a look at some digital indicators that we enlist in this post. We also rank them as well. To give you a quick preview, the following table shows their name, measurement range, resolution, NIST traceable certificates, and their carry weight.
Top 5 Best Digital Indicator Reviews 2021
1. Clockwise Tools DIGR-0055 Digital Indicator [Best Digital Indicator Overall]
Clockwise DIGR-0055 digital indicator has a specialty in price and reliability. This product requires a very comfortable price compared to all of the products here on the ranking. On the other hand, it has the certificate of calibration from NIST which ensures the reliability of the product.
General specifications are similar to others. The measuring range and resolution are 0-0.5″ and 0.0005″ respectively. The accuracy contained from this instrument is ±0.001″. It has a wide LCD of 1.6″ x 0.7″ and auto turn off in 5-7 mins. It saves the last measured value after it is turned on.
Another remarkable feature of this model is that it can transfer the measured value directly to the computer using a cable provided with the indicator. Note that we can’t use a regular USB cable. When we connect the instrument with the computer it automatically saves the data on the excel file. It not only saves time but also makes the operator feel more reliable on the product.
This precision instrument is made of stainless steel, so surely it ensures the mechanical long-lasting. It is about 12 ounces in weight and packaging size of 4.9 x 2.2 x 1 inch. Considering all the factors this model is the best of all. We strongly recommend this model for you.
- Reliable and accurate.
- Certificate of calibration.

- The zero setting is disabled after it turns on.
2. Neoteck DTI Digital Indicator [Best Budget Digital Indicator]
They have differences in two main specs. Neoteck has a measuring range of 0-1″ where the clockwise has only 0-0.5″. On the other hand, Neoteck doesn’t provide the certificate of calibration (NIST) with this indicator. So, it can’t assure its reliability and accuracy promise.
The rest of the specifications and accuracy are similar in both of the digital indicator. This model has also a resolution of 0.0005″ and an accuracy of ±0.001″. It has the facility to connect with the computer through the cable. It also saves the time of the operators and makes them feel more reliable like the clockwise model does.
This Neoteck digital indicator is 11.4 ounces in weight and packaging size of 5.1 x 0.8 x 0.9 inches. This model is the best alternative for the clockwise digital indicator. We strongly recommend this model as your alternative to the clockwise digital indicator.
- Accurate, simple, and easy to read.
- The provided guidebook makes the easy operation.
- Very comfortable price.
- No separate cable is available.
3. Mitutoyo 543-783B Absolute Digimatic Indicator [Best Pro]
Mitutoyo is a very professional and famous brand in the recent market. And this one, Mitutoyo 543-783B, is our third best product from our ranking. This model is very professional using in various mechanical machine operations.
It is more accurate than the clockwise indicator. The accuracy range is ±0.0008″ while the clockwise has only ±0.001″. It is reliable and promising for accurate readings. It is provided with the certificate of calibration from NIST.
The only difference for which we couldn’t take this as our best selection is its high price. Considering the other digital indicators, this model is double in price. That’s a downside of this model.
It can be connected with the STC cable with the other Mitutoyo dial display or can be connected to pc as an input system. It also saves time and helps the operator finish his works faster.
Besides, it has a measurement range of 0-0.5″, a weight of 9.6 ounces, and a packaging size of 4.3 x 3 x 7.5 inches. As we said this model is very professional for precision measurements. So, we strongly suggest this instrument for the most accurate product. But considering the price, we would better choose the other options.
- Accurate and reliable.
- Certificate of calibration
- STC I/O system
- Once the zero set is done, no need to do it again.
- Very expensive.
- It can’t be operated by a regular USB cable.
4. iGaging 35-0928 Digital Saw Gauge
iGaging is another best pick compared to the specifications from the models we took for the ranking. iGaging has also a remarkable position in the market. There are lots of suggestions and customer reviews for this digital indicator.
This digital indicator is built especially for the alignment tasks such as the table saw alignment, fence alignment, router, and drill press router runout, saw, etc. There are adjustable attachments will be provided with the dial indicator.
Well, it has a measuring range of 0-1″ and a resolution of 0.0005″ similar to most of the models here. It weighs 1.1 pounds which is telling us it is a little heavy. The whole body is made of stainless steel ensures mechanical long-lasting.
For any alignment precision measurements, this model can be our best choice. Besides the price range is very comfortable which goes with the quality of the products.
- Best for any table alignments.

Things to Figure Out Buying Digital Indicator
Obviously, accuracy is the most factor to consider. Most of our products here have a range of ±0.001″ of accuracy.
2. Measuring Range and Resolution
Measuring range and resolution is the next priority to consider. Clockwise and Mitutoyo digital DI has a measuring range of 0-0.5″ and 0-1″ for the other three respectively. All of the products have a measuring range of 0.0005″ of resolution.
3. NIST Traceability Certificate
NIST traceability certificate is another important factor to believe that a product has valid accuracy. This certificate shows that your instrument is traceable to NIST standards.
4. IP Rating
As a precision measuring tool that comes as a digital type, a broken electronic circuit can lead to misleading measurement errors. Therefore, that stuff must be tested using the IP testing procedure. This rating represents how well the measuring tool is able to resist water and dust.
Based on the accuracy and reliability, Clockwise Tools DIGR-0055 and the Mitutoyo 543-783B are today’s best electronic indicators on the market. Especially the Mitutoyo dial indicator, it’s great for professionals. On the other side, Clockwise is the best budget choice. Then Neoteck, iGaging, and Fowler are the alternatives.
