Practical steps to overcome fiber optic attenuation
2025년 10월 24일 16시 08분 29초

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.

What is H₂S? Effects of H₂S gas on health and environment
2025년 10월 20일 14시 24분 46초

H₂S or hydrogen sulfide is a colorless gas with a characteristic rotten egg odor and often appears in natural or industrial processes such as wastewater treatment, oil and gas exploitation or organic matter decomposition. This gas is toxic even at low concentrations, causing respiratory inhibition and loss of the ability to sense odors upon prolonged exposure. The following article by EMIN will help you understand the properties of H₂S, how to recognize risks and necessary measures to limit its impact on health and the working environment.

What is the most suitable humidity and temperature to store cameras?
2025년 10월 17일 09시 38분 10초

If you want sharp photos, first of all, you need to keep your camera in the best condition after each shooting. The storage environment plays an important role, especially humidity and temperature. If not controlled, the internal components can be easily damaged, the lens can be moldy or yellowed. So, what is the ideal humidity level to store the camera? What temperature is safe? And when not in use, how should you store it to keep it durable and stable? Let's follow along!

Determine COD index in wastewater, how to treat?
2025년 10월 15일 14시 03분 15초

Domestic wastewater is a source of many organic and inorganic pollutants, with notable indicators such as BOD, COD, Nitrogen or Ammonia. In which, COD is an important parameter reflecting the level of organic pollution in water and often exceeds the allowable threshold if not controlled. So how is COD measured and what measures are there to effectively handle it? Let's find out the details with EMIN in the article below!

Multimeter exploded during ACV measurement? How to handle?
2025년 10월 15일 10시 07분 08초

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.

Why is pH important and needs to be continuously monitored in beer production?
2025년 10월 14일 14시 38분 19초

pH is the foundation of beer’s sensory profile. When maintained within the ideal range, yeast performs consistently, fermentation proceeds properly, and natural aromatic compounds such as esters and phenols are formed. These compounds give beer its distinctive aroma, make the bitterness more pleasant, and create a smooth aftertaste.

Procedure for Proper Inspection, Cleaning, and Maintenance of Optical Connectors
2025년 10월 14일 08시 58분 38초

In optical transmission systems, connectors are the final contact point between devices and fiber cables, and also the most common source of errors. Even a thin layer of dust or a small trace of oil can cause signal reflection, leading to several decibels of loss. Sometimes, an entire transmission line stretching hundreds of meters can lose signal simply because a connector end is not clean. Anyone who has ever installed optical networks, pulled camera lines, or maintained telecommunications infrastructure has likely faced this situation: the OTDR trace looks perfect, yet the signal is still lost. Upon closer inspection, a speck of dust is found right at the connector’s contact core. From such small issues, many engineers have gradually developed the habit of always inspecting and cleaning connectors before performing any operation, considering it a mandatory step in their workflow.
