Best Dial Indicator

Dial indicator is the dialing display which indicates a circular scaling value of a measured object. This instrument is used to make a product more accurate by measuring distances, angle, height or surface errors, etc. Therefore, the dial indicator is used in the primary measuring of engine building, metalworking, deck clearance, crankshaft thrust and straightness, lifter travel, etc.

There are several types of dial indicators such as balanced reading dial indicator, dial test indicator, plunger dial indicator, lever dial indicator, continuous dial indicator, reversed balanced dial indicator, reversed continuous dial indicator, etc.

Based on different measuring positions, these dial indicators are classified into different structural formations. In this article, we are going to explain on plunger type dial indicator which is named as just a dial indicator.

The general structure of a dial indicator consists of the circular body, circular gear, pointer, linear gear, circular dial, and a plunger.

Now you have a quick idea of what the dial indicator is. Another thing to be aware of is to make sure you are not picking the test indicator. They are the same in their measuring methods, however, they are different in terms of structure formation and facilities of measuring positions. Keep reading until the buying guide section to read the brief differences of them.

Factors to Consider during the Selection

Dial Indicator’s main task is to measure, so accuracy is an important topic here. Other than accuracy, there are other important factors we need to consider while choosing the best dial indicator.

1. Accuracy

While measuring components, accuracy is the main priority. So, the accuracy of a dial indicator is very important for the buyers. Here, in this review, most of the products have 0.001″ per 1-inch accuracy which is sufficient for any accurate measurement.

2. Material

Why material is important to consider? Because a silver gear will long last than a plastic gear. Though plastic gear is light and suitable for tiny instruments, but yet metal’s co-efficient is more accurate. A plastic will erode after it is used for around time, and the pointer will give an inaccurate measurement which may make unexpected errors. Most of our products here are made off metals and plastics.

3. Customer Review

The customer review is one of the most important factors while choosing any product. Product’s performances can be found well explained by the previous buyers.

4. Price

Price is always an important issue while buying things. Sometimes good quality differs with the price, sometimes brand matters. So, if you are looking for quality, not to focus on the price will be the best decision.

5. Buy Dial Indicator, NOT Dial Test Indicator

It’s important to make sure that you are not picking the wrong one. Dial indicator is different from the dial test indicator (test indicator). You have to be aware of the differences between the dial indicator and test indicator. It can take a pretty long explanation, however, we can distinguish them as the following list:

Dial Indicator:

  1. Plunger contact type
  2. Larger and heavier
  3. Vertically excels
  4. Repetitive and comparative
  5. Measures depth of holes, flatness, runout, roundness (vertical measurement, can’t excel angular measurement), so can’t be well placed in a lathe machine other than vertical position.
  6. 5 revolutions
  7. Lower resolution 0.001″ to 0.0001″ (typical resolution)
  8. Specific use in some applications such as primary measuring of engine building, deck clearances, crankshaft thrust and straightness, lifter travel, etc.
  9. Visibility is clear
  10. Both clockwise and anticlockwise rotation and dials continuous reading

Test Indicator:

  1. Lever contact type
  2. Smaller and lighter
  3. Travers one or two dimensions, measures flatness, runout, roundness (can’t measure the depth of holes)
  4. More flexible orientation
  5. Visibility is not so good (because of its size)
  6. Consistency measurement
  7. Vertical, horizontal or angular excel
  8. Higher-resolution but short measurement range .0001″ to 0.00005″
  9. Clockwise rotation and dials continuous reading
  10. Allows single revolution
  11. More often in use

Summary

We have shortly described all the product specifications. Now you are expected to be able to distinguish the differences between the specifications in them. All these dial indicators are in the best position in the market. Actually, there are few more other dial indicators in the market such as HHIP, HFS(R), etc but we didn’t pick them due to their lower ratings and the poor customer reviews.

Here from this article, a common question may arise is why the price wasn’t the main priority? Because we focus on product performance with the best pick from the market. The Triton dial indicator is the winner of our review based on today’s market.

Besides, if you think about the accessibility then KHCRAFT will be the best in here. It has some wonderful features of accessing facilities. If we are looking for a strong stable and durable dial indicator we can go for the metallic geared models, stay away from the plastic ones.

Finally, we hope this article will help you to understand what exactly the position of the dial indicators in the market. This will help your research easier and faster. We hope for your awesome journey in choosing the best dial indicator. Best of luck with your project.
