FAQ Section
Q1: What is the main difference between a dial indicator and a dial test indicator?
A1: A standard dial indicator (like the Dial Indicator SAE 0-1″) typically measures displacement along an axis, often with a plunger moving in and out, and usually has a larger measurement range. A dial test indicator (like the Neoteck Dial Test Indicator) usually has a swiveling contact point and a much smaller measurement range but is designed to detect small variations and deviations, often in tight spaces or for alignment tasks. Both are among the best dial indicators to buy for specific jobs.
Q2: What does “0.001” resolution” or “0.0005” accuracy” mean for a dial indicator?
A2: Resolution refers to the smallest increment the indicator can display (e.g., one thousandth or half a thousandth of an inch). Accuracy is how close the indicator’s reading is to the true value. Higher resolution and better accuracy are crucial for precision work, and you’ll find these specs highlighted in descriptions of the best dial indicators to buy.
Q3: Is a magnetic base necessary for a dial indicator?
A3: While not strictly necessary for all applications (some indicators have lug backs for mounting), a magnetic base (like the HFS (R) Magnetic Base Indicator Back Holder) offers incredible versatility and stability. It allows you to quickly and securely mount your indicator to any ferrous metal surface, which is extremely helpful for machine setup, checking runout, and more. Many of the best dial indicators to buy are offered as kits with magnetic bases.
Q4: Can these dial indicators be used for automotive repair?
A4: Absolutely! Many of the precision tasks in automotive repair, such as checking brake rotor runout, crankshaft end play, valve lift, or gear backlash, benefit greatly from the accuracy of a dial indicator. The Neoteck Dial Test Indicator and HDLNKAK Professional Dial Test Indicator with Magnetic Base, for instance, are excellent choices for such work.
Q5: What is NIST traceability and why is it important?
A5: NIST traceability means that the calibration of the instrument (like the SPI 22-301-6 Deluxe AGD2) can be traced back to standards maintained by the National Institute of Standards and Technology. This certification ensures that the instrument’s measurements conform to nationally recognized standards, which is vital for quality control, industrial applications, and any situation where verified accuracy is critical. It’s a key feature to look for in the best dial indicators to buy for professional use.
Q6: How do I choose the right dial indicator for my budget?
A6: Consider the level of precision and the type of tasks you’ll be performing most often. For general workshop use or a tighter budget, a reliable mechanical dial indicator with 0.001″ resolution will be sufficient. If you need higher precision (0.0005″) for intricate measurements or professional work, expect to invest more in a dial test indicator or a kit with a magnetic base. Don’t forget to factor in useful accessories like extension rods or contact point sets, which can significantly enhance the value of your chosen indicator. Looking through reviews for the best dial indicators to buy can help you find a good balance of features and cost.
