Multimeters and voltmeters may seem the same to any other person but to an electrician or electrical engineer. These two measuring devices are different in many ways. But as their names suggest, a voltmeter measures only voltage. On the other hand, a multimeter can measure more than one electrical parameter, including voltage, current, resistance, capacitance, … Read more
How to know that your protractor is accurate? What is the way to assess that your protractor’s accuracy is still within the permissible accuracy (tolerance)? What if your protractor actually needs a replacement? All of these questions can be answered with a protractor calibration. This article will provide a basic idea of the techniques for calibrating … Read more
Being a service technician for an underground utility system is challenging. But if you love your work, having the appropriate devices and equipment in your arsenal should be your priority. The human eye cannot see anything below the earth’s surface. That is not a problem if you have the right tools. Underground has a system … Read more
Many utility infrastructures are buried deep underground. They include telephone lines, electrical, fiber optic, and data cables. These are usually challenging to engineers and maintenance technicians since locating faults is not straightforward. You cannot dig the entire cable length to identify the fault position. That is where the underground cable fault locators come in. Unlike … Read more
Vernier protractor or vernier bevel protractor is an important tool in angle measurement. Not only for measurement but also for layout, it can be a decisive tool for accuracy and precision in which the resolution of the vernier protractor reaches up to 5 minutes. The same as the analog vernier caliper and vernier height gauge, … Read more
So far, the Geiger counter is the best radiation monitor option for personal use. It’s compact, relatively affordable, and widely available device on the market. Not only does it measure the radiation particles around us but also monitors the dose rate (dosimeter). You can also make your own Gieger counter because the tube is also … Read more
Both repeatability and reproducibility are important in measurement and research. If you are the operator of a particular precision measuring instrument, you have to know these two terms. Your instrument has to be repeatable. It means you take several readings and you get the same readings. If there is a variation, then you have to … Read more
We use a paint thickness gauge to measure the vehicle’s surface paint. Touch the probe to the car panel surface, and it will take the reading. It’s not only the main object to measure with this paint meter, it also measures other coatings such as the pipe coating, etc. The base of the paint/coating may … Read more
Sometimes, it’s not easy to differentiate between squareness, perpendicularity, and parallelism. They are almost the same and have a close correlation. Even, squareness and perpendicularity are frequently used interchangeably while in fact, they are actually different. On this great occasion, we are glad to present an article that covers the explanation of these terms. Differences … Read more
Rafter square, speed square, triangle square, and rafter angle square are actually the same tools in spite of their different names. This tool is used for a range of applications such as measuring, layout, marking, and scribing guide, it acts as a saw guide for 90- and 45-degree cuts, establishes perpendicular angles, and makes rafters. … Read more
