2026年04月24日 15時36分34秒

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?

How to choose an Infrared Thermometer for Maximum Accuracy
2026年04月23日 15時39分04秒

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.
