Any of us have been familiar with “stainless steel”. There are countless tools made of stainless steel such as measuring tools, kitchen equipment, automotive parts, cutting tools, etc. However, do you really recognize it? Why when it comes to corrosion-proof tools, people go for items made of this metal? Here we will discover it. What … Read more
In this page, we are going to learn together what is analog to digital converter. This topic is very important to learn in measuring instrumentation. Most of the microcontroller (though no merely) are able to convert analog to a digital signal. An analog signal can be a voltage signal. While the digital signal can be … Read more
The first thing that you have to know is that there is not exactly accurate measurement. Error is anywhere. As a human, we cannot realize the hidden error that is caused by the environment and also the internal system of the measuring instrument. Because we cannot spot the error, it’s reasonable we doubt the reading. … Read more
Traceability in measurement or measurement traceability is the condition where no links are missing to the real agreed reference standard. The real agreed reference standard means a particular reference that the nations over the world agree to establish it as standard. For example, the nations over the world establish the path traveled by light in … Read more
Parallelism and flatness are two terms in measurement that contribute to the accuracy of your precision instrument. Especially when working with a micrometer, flatness and parallelism takes an important role to generate a reliable measurement. But what are actually parallelism and flatness? These two words seem to be similar to hear. But they are actually … Read more
Have you ever realized that the measuring tools we recommend often labeled with this kind of rating code: IP64, IP65, IP67? Such as the best digital micrometer Mitutoyo 293-340-30 IP65. Yap, it’s the code that we are covering here. It’s the code that informs the users in a quick way about something. What is IP … Read more
You may have heard that a particular precision measuring tool has a certain tolerance number, for example, ±0.001mm like the Mitutoyo Micrometer 293-340 series have. You can find it as well on the other precision tools. What is it actually? Tolerance can be defined as the total allowable amount by which a measurement may vary. … Read more
It was the 19th century when a scientist James Clerk Maxwell put forwarded the concept of a consistent system where the fundamental small units were the base and the rest were derived from them. This coherent system was the metric system with almost all of the dimensions either based or derived from the ratios of … Read more
Imperial units have their origin from the time of Romans in the middle ages. The units used evolved since then and their values changed with time until Britain recognized it as a system. The imperial unit system was formally established under the Weights and Measures Act of 1824 and the Act of 1878. The definition … Read more
Suppose you are measuring with a caliper, then you suddenly get quite confused. You ask, “Why must the aligned line that gets counted on the vernier scale? How that could be?” If you are in a situation like this, this is a good chance to learn it. Vernier scale is the secondary scale that is … Read more
