What is a comparator stand?
The comparator stand is one of the most effective measuring equipment which is used for the comparison of multiple parameters in the industries. In these stands, users can make precision measurements of a workpiece by mounting a dial, digital Indicator or a probe.Â
Dial comparator stands are used for the measurement of the height of small parts like bearing ring width, roller height, bush height, and many more. Dial comparator stands can be compact and easy to carry or can have large bases with long shafts which can be used to measure bulky parts in Metrology labs, machine shops, and production departments. In a mass production unit, where components need to be checked at a rapid rate, using a micrometer to take measurements can be an extremely time-consuming process, in this case a comparator stand makes more sense.
How to use a comparator stand?

For the demo we have used a simple comparator stand which is affordable and easy to use: the Jafuji Comparator stand available with Bombay Tools Supplying Agency Pvt. Ltd
Jafuji comparator stands are available from 150×100 mm all the way up to 400×300 mm bases, and the base size, as well as shaft length, can be customized as per the customers’ requirements. The stand can be used with both mechanical and digital dials as well as probes. Some comparator stands such as this one is available even with dust grooves or serration which enable the dust to settle within the grooves thereby ensuring the highest accuracy.Â
What are some of the main points to keep in mind while using a comparator stand?
It is critical for the comparator stand to have a flat base and a shaft that is perpendicular to this base. Since the measurements are in micron level, small deviations in flatness or perpendicular may impact the readings. Jafuji comparator stands come with a NABL calibration report that certifies the flatness as well as whether the stand is perpendicular.Â
It is also extremely important that no dust accumulates on the comparator stand since that will affect the accuracy of the measurements.
