Dissolved oxygen meter helps determine the amount of oxygen in water using DO sensor. Choosing the right measuring technology and equipment for each environment is the condition to ensure accuracy and efficiency.

Breakdown voltage represents the limit to which a material can maintain its insulating ability before a discharge occurs. When this value is reduced, the insulation has lost its stability and there is a risk of short circuit, leakage or equipment failure.

During the use of air quality meters, it is not uncommon for the device to display error codes such as E1, E2, E3. This is usually a sign that the sensor is malfunctioning, the device is affected by environmental conditions or needs to be recalibrated after a period of operation.

Particulate Matter (PM) is classified based on its aerodynamic diameter, which determines how particles move through the air and enter the human respiratory system. This is the basis for organizations such as WHO or EPA to develop air quality monitoring standards.

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.

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!

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!

Automate the water neutralization and treatment process thanks to the pH and ORP sensor system combined with a dosing pump that responds to real-world data.

Manganese is a metal that is widely used in many areas of life and production. However, not everyone fully understands its role. In this article, I will join everyone to learn more clearly and practically about Manganese. We will start from the atomic structure, delve into the importance of Manganese in the metallurgy and steel production industry. In addition, Manganese also appears in agriculture with direct impacts on crops. Finally, there are safety warnings that anyone working or exposed to Manganese should pay attention to.
