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
A practical overview of colorimeters, from tristimulus measurement and color difference data to routine quality-control applications.
When colors are inconsistent or differ from the specified requirements, factories may face difficulties maintaining product consistency and a consistent brand image. Factories should clearly define their color control requirements, compare different types of equipment, and conduct practical testing before selecting the right color measurement instrument.
The OWON HDS120 series combines multimeter functions and oscilloscope waveform viewing in one portable instrument for electrical measurement tasks.
The OWON OWH67 series is a high-power programmable DC power supply range designed for laboratory and industrial rack-mounted applications.
The OWON SPS series combines fanless operation, single-channel programmable DC output, constant-power operation, waveform functions, and integrated protection features.
How does the Mohs scale rank gemstone hardness? Why does the metal industry require more precise measurement methods, such as Rockwell, Vickers, and Brinell?
Industrial rubber typically falls within the 40–80 Shore A range, though there is no single standard hardness for all types; components such as gaskets, seals, vibration dampers, and rollers may utilize different hardness levels depending on specific requirements. Temperature also significantly affects measurement results: heated rubber tends to soften—lowering the Shore A value—while cold rubber tends to harden, causing the Shore A reading to rise.
