Parallelism Vs. Flatness

Parallelism and flatness are two terms in measurement that contribute to the accuracy of your precision instrument. Especially when working with a micrometer, the flatness of the flat anvil must have a good condition. Besides, when dealing with gauge blocks, the gauge blocks’ flatness and parallelism determine their grade. But what are actually parallelism and … Read more

IP Rating Scale Explained

Some of the products that we recommend (sewer camera, underground wire locator, digital micrometer, Elcometer 311-B paint thickness meter, digital caliper, etc), often come with an IP rating. If you find them with codes such as IP64, IP65, IP67, it’s IP rating. For the easiest product example, you could check the Mitutoyo 293-340-30 that has … Read more

Tolerance in Measurement

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

Imperial Unit System

When it comes to precision measurement tools and devices such as mechanical micrometer, caliper, indicator, etc, we take the reading in inch reading. You need to know the inch reading is actually an imperial unit system. Here we are going to briefly discuss imperial unit system including its history, the units, and countries that keep … Read more

List of Linear Measurement Tools

When it comes to linear measurements, it means length, width, height, thickness, depth, diagonal, diameter, etc. It is about the straight or shortest distance between two points. Length is one of the most measured linear distances. Tools to measure length have been existing from the beginning of humanity. People utilized fingers to measure short length … Read more

Accuracy Vs. Precision

Accuracy and precision are some of the most fundamental things in measurement system. These two terms represent how good a certain measuring/sensing instrument. It determines how appropriate a measuring instrument to a particular application. However, in some cases, it’s kind of confusing to differentiate them. Sometimes people say, it’s a high precision instrument. On the … Read more

158 Physical Quantities and Units

Physical quantities and units are among the basic things in measurement that you have to know. When learning about physics, engineering, instrumentation, and metrology, you are not far from physical quantities and units. In regard to buying a measuring device, it goes the same thing, physical quantities and units are the most fundamental thing you … Read more

What is Instrumentation?

Instrumentation is the term used to refer both single instrument and a collective of instruments. The single instrument may perform physical quantity detection, measurement, analyzing and even magnification. This single instrument can work together with other instruments to perform a particular task; without being connected using a communication line. On the other hand, a collective … Read more
