Repeatability in Measurement

Repeatability in measurement is a vital aspect when it comes to precision in measurement. Along with reproducibility, you get two aspects of precision to analyze. They show how consistent a repeated measurement is. As a result, it generates a reliable measurement. Learning about measurement repeatability is not only important in the field of metrology but … Read more

What is ADC (Analog to Digital Converter)?

An ADC (analog to digital converter) is an electronic circuit that converts the analog data (continuous) from nature into digital data (binary). The ADC circuits can be found as a stand-alone ADC IC module or embedded into microcontrollers. The following features are best for you to understand before you go deeper about ADC. ADC Features … Read more

Uncertainty in Measurement

How could you know that your measurement result is 100% accurate? Is that because you use an accurate measuring instrument? Not that easy. What if there are many things that you are missing; things that you have to take into account. External and internal sources such as temperature, humidity, heat thermal coefficient, operator error (parallax … Read more

Measurement Traceability

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

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, 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

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

Metric Unit System

When buying a dial indicator, for example, and you choose one that has millimeter graduation instead of inch graduation, that means you choose the metric dial indicator. The term metric dial indicator means the dial indicator that uses a metric unit system. Dial indicator is not the only measuring tool that uses metric or imperial … 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
