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.

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

An overview of the CHN SPEC SPF-660 Series and its stated capabilities for in vitro sunscreen research, formula screening, and spectral measurement 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
