What is colorimetry: Colorimetry is simply the measurement of color. Colorimetry is the determination of the concentration of a substance by measuring the relative absorption of light relative to a known concentration of the substance. In visual colorimetry, natural or artificial white light is usually used as the light source, and measurements are usually made using a simple instrument called a c...
Introduction Automotive, aerospace, construction, and maritime sectors all face major corrosion challenges. Manufacturers use coatings and metals with high corrosion resistance to counteract corrosion’s destructive effects. The materials’ long-term performance and durability depend on accurate assessments of their corrosion resistance. To evaluate the efficacy of coatings and metals in...
Gloss meter is an instrument used to measure the surface gloss of ceramics, paints, inks, plastics, marble, aluminum, electroplating, hardware and other materials. Gloss is an important optical index for the appearance of an object, reflecting the specular reflection ability of the material surface, and GU is usually used as the unit of gloss. Gloss is a physical quantity that evaluates the abilit...
Introduction Telecommunication networks are the backbone of today’s communication systems, allowing for the unhindered transfer of text, audio, video, and other types of data. Electromagnetic interference (EMI) from sources including neighboring electronics, power lines, and RF waves may disrupt these networks’ functionality. Signal integrity, network throughput, and service dependabil...
The birth of colorimeter is to detect color difference and bring more convenience to industrial production to reduce the loss caused by color difference. People in modern life have higher and higher requirements for the color of goods. Simple color difference may break the image of a brand in the minds of consumers, which has a great impact on its reputation. The development and use of color diffe...
Introduction The ability of materials and coatings to resist corrosion may be evaluated via the use of salt spray testing. Validation and calibration of salt spray test chambers has to be carried out on a regular basis in order to ensure accurate and trustworthy test results. Validation and calibration must be performed on the testing environment, which includes the chamber as well as the temperat...
What are the precautions before using the waterproof test equipment? 1. Place the device on a stable ground to ensure that the device is stable and not easy to fall over, and it is strictly forbidden to use power sources other than the specified frequency. 2. Check whether all the interfaces and pipelines of the equipment are firm to ensure that there will be no water leakage during the test. Be ...
Introduction Electronics and electrical systems have become more important in the contemporary automobile industry. The components, including the engine control unit, the infotainment system, the safety features, and more, are all powered by these systems. However, voltage fluctuations, electromagnetic interference, and power surges are all hazards in a vehicular setting. Surge generators are esse...
Introduction Goniophotometers are a vital instrument for lighting researchers, including scientists, engineers, and designers who are trying to advance the state of the art in lighting. These high-tech instruments allow for accurate measurement and investigation of the features of light distribution, which results in the production of essential data on the efficiency, productivity, and quality of ...
