What is a spectrophotometer? The spectrophotometer uses the grating spectrophotometer principle for color measurement. A grating is an optical element that is engraved with a set of parallel periodic lines or grooves (often inclined) on a plane. When a beam of compound light is incident on the grating plane, its periodic structure will undergo diffraction, and the transmitted or reflected diffrac...
Introduction The use of high precision spectroradiometer integrating sphere systems has had a significant and positive influence on both the science of colorimetry as well as the measurement of light. Measurements of color rendering indices, color features, and spectral power distributions are all made more accurate with the help of these high-tech instruments. In order to get reliable data from s...
Introduction Electronic device R&D and testing rely heavily on temperature and humidity chambers. Electronic devices must prove their dependability, performance, and durability across a wide range of environmental conditions as technology develops and customer expectations increase. Engineers may speed up the development process and improve product quality by using temperature humidity chamber...

I. ES SO2 Cause Corrosion? The answer is yes. Sulfur dioxide (SO2) is a common and relatively simple sulfur oxide and one of the major air pollutants. It has strong corrosivity and reacts with homogeneous materials to form salt substances to corrode the surface of the material and disintegrate the material into particles, eventually causing the material to age, fail and damage, and also affecting ...
Introduction The railway system is an important part of the transportation network because it allows people and products to move quickly and safely. Electromagnetic compatibility (EMC) and safety testing are becoming more important as these systems get more complex and combine electrical and wireless technology. The performance, reliability, and safety of railway systems are all seriously threaten...
Alloy analyzer is an on-site determination tool based on X-ray theory, which is widely used in military industry, aerospace, steel, petrochemical, power, pharmaceutical and other industries to quickly identify the elements in metal materials. Traditional methods for metal analysis usually adopt chemical analysis, which calculates the content of each element through chemical reactions and weighing ...
Introduction Coatings designed specifically to protect surfaces from things like corrosion, wear, and environmental degradation are invaluable. Salt spray testing has become an important means of evaluating products to assure their longevity and functionality. This article delves into the relevance of salt spray testing and how it evaluates the durability and efficacy of protective coatings under ...
