Dear Customers, Partners, and Employees of EMIN Vietnam, we would like to announce the holiday schedule for Hung Kings' Commemoration Day, Liberation of Southern Vietnam Day (April 30th), and International Labor Day (May 1st) in 2026.
In environmental noise reports or technical specifications of household appliances, we often encounter the figure 50dB. But in reality, does a 50dB noise level cause discomfort or affect health?
In daily life as well as industrial production, noise is increasingly becoming a serious form of environmental pollution. It silently has negative impacts on human hearing and the nervous system.
In real industrial operations, owning an expensive infrared thermometer does not automatically guarantee accurate readings. Measurement errors rarely stem from sensor quality; instead, they often arise from a mismatch between the device and the physical properties of the surface being measured. Engineers need to look beyond the basics and understand the underlying barriers related to wavelength and optics—factors that are rarely addressed in general documentation.
In backup power systems (UPS), telecommunications, solar energy, or automotive starting systems, 12V batteries are widely used. However, a common mistake among users and even technicians is relying solely on voltage (V) while ignoring the key factor that truly determines discharge capability—the internal resistance.
