Radiation is the transfer of energy through space or matter by electromagnetic waves or energetic particles. It occurs everywhere, from sunlight and medical X-rays to radioactive sources used in industry and research.

When constructing, installing or maintaining fiber optic cable systems, measuring devices such as VFL, OTDR or OPM are indispensable tools to check signals and determine fault points on the cable line. Depending on each actual situation, technicians may need to combine many types of equipment to accurately determine the cause and location of the problem, thereby providing appropriate solutions.

“Hello EMIN Vietnam, I'm Nam. Let me ask: Does the Fluke thermal camera have autofocus? And where can I buy the genuine one in Hanoi?” A practical question that EMIN receives quite often. Find out the answer below!

The Optical Fault Locator (VFL), commonly known as a fiber optic scope or red light source, is one of the basic yet essential tools in any fiber optic professional's toolbox.

When testing vibration, engineers see the values ​​displayed on the meter screen. But what really matters is the unit behind the number. The same value expressed in velocity or acceleration has a completely different technical meaning and warning level.

In the production environment, the lighting system not only affects work efficiency but also directly affects the life of equipment, power consumption and operator safety. Each type of lamp, from fluorescent, LED to halogen, has its own operating principle and advantages and disadvantages. Carefully analyzing the characteristics of each type will help determine which is the optimal choice for each area in the factory.

When working with electronic devices, you must have heard about connecting an oscilloscope to a computer and wondered why this operation is so popular. This connection helps to expand the ability to observe signals and increase the speed of testing and analysis during work. You will be surprised by the convenience it brings, especially when experiencing devices like Rigol MHO98, one of the newly launched models with many modern features.

Fiber loss is the cause of light signal weakening during transmission, affecting the performance of the entire network system. This article summarizes specific and easy-to-apply steps to overcome fiber loss, helping you maintain a stable network and smoother transmission.

A Handheld Spectrum Analyzer is a device designed to measure and analyze RF signals in a variety of frequency bands.

When using a multimeter to measure electrical parameters, users may sometimes encounter many problems, from small errors such as incorrect display to more serious damage to the device. In some cases, the meter can even explode during measurement. What is the cause and how to handle this situation, especially when measuring ACV voltage (alternating current voltage)? Let's find out how to protect the device and ensure your own safety when operating.
