The word micrometer itself is a combination of two Greek words. These words are “micros and “metron”, the meaning of micros is small and the meaning of metron is measure, both of them combine to give micrometer its name. William Gascoigne was an astronomer who first invented a micrometric screw while measuring the star in … Read more
One of the reasons why you should choose tape measures as your length measuring tool is their easy-to-maintain advantage while it provides great functions that you can’t obtain from an ordinary length measuring tool. Even though easy, if you don’t take care of it properly, it will break apart early. Here are some simple tips … Read more
A tape measure is actually a long ruler that can be bent and rolled-up so that we can get it housed in a case then pick it anywhere. It is a problem solver when we need a portable long-range ruler. That’s why carpenters, builders, etc are those who always pick tape measures for their measurement needs. … Read more
Calibration is to find out the measurement error. According to the measurement error that is observed, verification is to decide whether it is within the tolerance (permissible error) or not. Then, validation is to make sure it measures what it’s meant to. In some cases, verification and validation overlap. Calibration According to NIST, calibration is … Read more
You may wonder about the differences between the gauge and instrument. Both of them we use in many times and many places. In this post, we will briefly break down their differences. 1. Gauge A gauge comes in a fixed dimension which has only a single readout. For example, a single feeler gauge comes in … Read more
Two things to get a better understanding of how the gauss meter works: Hall effect and Lorentz force. Gauss meter works making use of the Hall effect. The semiconductor of the Hall effect sensor is charged with current. The magnetic field will pull or push electrons in the semiconductor and then creating voltage differences. This … Read more
The first time using a micrometer, you may get a little stunning fuzzy because you don’t know what to start from. Can’t keep silent, you decide to try measuring. Stop it, please! You could ruin the micrometer’s accuracy because rotating the thimble too tight. Using a micrometer is actually easy. There are only some steps … Read more
After you learn how to use the micrometer, the next basic is how to read the micrometer or taking the reading. The unit system that’s used in micrometers has two versions. Therefore in this page, we cover how to read a micrometer in those two versions: metric (mm) and imperial (inch). Reading a micrometer is … Read more
Measurement traceability or the fancy term “metrological traceability” is an important element in relation to accuracy. Someone may claim they are accurate, however, without measurement traceability, it’s just a claim. If you are going to hire a calibration service for your measuring instruments, this is an interesting topic for you. You have to make sure … Read more
A micrometer is one of the linear measuring instruments, provides accuracy down to 1/100 of a millimeter. Even, some of them can reach 1µm accuracy. It’s truly a hand-held tool that you can rely on to measure something very thin or to get more detail about the thickness, length, diameter, and depth of an object. … Read more
