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.

Memory depth determines how many data points an oscilloscope can store during a single acquisition. This parameter directly affects the actual sampling rate, observation time, and the ability to capture and analyze abnormal events.

Both Shore A and Shore D are used to measure material hardness, but each scale is suited to a different group of materials. Soft rubber, silicone, or elastic gaskets are typically tested using Shore A, whereas hard plastics, engineering plastics, and materials with low deformation are better suited to Shore D

Equipment restarts in a factory setting can be attributed to voltage sags, momentary power outages, electrical noise, overheating, or hardware faults. For incidents that last only a few power cycles, a power quality analyzer can capture voltage, current, and waveform data at the exact moment of the reset, thereby helping engineers determine whether the power supply is the cause
