A circuit board may function normally yet still consume significant power in standby mode. Particularly in IoT devices, wireless sensors, battery-operated equipment, or low-power control circuits, a difference of just a few microamperes in sleep current can significantly impact battery life

A Type K temperature probe may gradually become less accurate after prolonged use due to aging, oxidation, and changes in the probe’s thermoelectric characteristics. The higher the temperature and the longer the exposure time, the more noticeable these effects can become.

Mr. Le Van Truong, Head of the Technical Department at EMIN, shares insights into the processes behind a project handover—ranging from site surveys and risk management at the factory to how a technical lead makes on-the-spot decisions and turns every trip into a shared learning experience for the entire department.

Gloss is not a factor separate from color; the two characteristics work together to determine the final appearance of the printed product. Systematic measurement enables businesses to better control surface quality, detect variations early, and maintain consistency in the finished product.

Multispectral cameras capture spectral data across multiple wavelengths, whereas standard cameras primarily serve to record visual images.

Color measurement can be performed through visual observation or with the use of measuring instruments. Regardless of the method, it is important to clearly define the sample being evaluated, the viewing or measurement conditions, the comparison criteria, and how the resulting data will be interpreted.

A practical guide to matching EL detector pixel count with photovoltaic module inspection needs, defect visibility requirements, and inspection workflows.

Multimeters can still measure small currents, but only up to a certain limit. When the current drops to the µA or nA range—or lower—the device's resolution, background noise, and stability begin to directly affect the results. This is when a picoammeter or a specialized current-measuring instrument is required

Metamerism can cause fabric samples to appear color-matched at the factory but show noticeable color differences in stores or under natural daylight. Evaluating colors under multiple light sources helps control this risk by providing objective color data standard.

Colorimeters help convert subjective color assessments into measurable, comparable data, enabling early detection of color deviations and supporting consistent color control throughout multiple stages of production.
