Frequently Asked Questions
What are the most important differences between gauge blocks?
The most important differences between gauge blocks are their size, material, and accuracy grade. Size is important because it determines the range of measurements that can be made using the block. Material is also important because it affects the block's durability, corrosion resistance, and thermal properties. Accuracy grade is important because it determines how precisely the block can measure. Some blocks come with a NIST traceable certificate to ensure their accuracy. Gauge blocks may be available as part of a set.
How do I choose the right gauge block?
To choose the right gauge block, you need to consider the size, material, accuracy, and cost of the block. You should also consider your specific needs and applications. If you need a block that is very precise, you will need to purchase a high-accuracy block. If you need a block that is durable and corrosion-resistant, you will need to purchase a block made of a material such as steel or ceramic.
What are gauge blocks used for?
Gauge blocks are used to set and check the accuracy of measuring instruments such as calipers, micrometers, and height gauges. They can also be used to calibrate machine tools and other precision equipment.
How do I use a gauge block?
To use a gauge block, clean it with a soft cloth and then place it on a flat surface. Position the measuring instrument next to the gauge block and then adjust the instrument to the desired measurement. You can then use the gauge block to verify the accuracy of the measuring instrument.
What are the disadvantages of gauge blocks?
Gauge blocks are relatively expensive and they can be easily damaged if not handled properly. They also require careful storage to avoid damage and contamination and can be sensitive to temperature changes.
