High and Low Temperature Thermal Shock Chamber are used in electronic and electrical components, automation components, communication components, automotive parts, metals, chemical materials, plastics and other industries, as well as in the physical changes of national defense industry, aerospace, military industry, BGA, PCB base plates, electronic chip ICs, semiconductor ceramics, and polymer ma...
Isolation transformers, also known as safety transformers, are transformers designed to electrically isolate the input winding from the output winding. They are used to isolate two or more coupled circuits electrically. The primary function of isolation transformers includes facilitating safe operations during machine maintenance and upkeep, providing protection against lightning and filtering fun...
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 diffraction light will also interfer...
Drop Testing Standards: GB/T2423.8, ISTA, IEC60068-2-32, GB/T4857.5, GJB150, IEC60068-2-27 1. Application and Purpose of Drop Testing Machines: With the rapid development of the logistics industry, paper boxes and packaging materials often suffer from collisions and falls during transportation. Drop testing machines are mainly used to simulate the impact of falls on packaging materials during tran...
A spectrophotometer is an instrument used to measure the reflected spectral power and light characteristics of objects to determine their standard color values. However, measurement results can vary due to differences in color difference calculation methods and light source selection. Therefore, it is crucial to carefully select appropriate color difference formulas and light sources when using a ...
The pursuit of beauty by humans will not change over time. Nowadays, this pursuit is reflected in various aspects of life, and the most common one is the “practical art” of makeup. Based on this, the competition in the cosmetics industry is quite fierce. In order to capture customer requirements and showcase their creativity, the color of cosmetics is one of its intuitive and importan...
The rapid temperature change test chamber is suitable for “safety testing of electrical components and provides reliability testing, product screening testing”, and can also “improve product reliability and quality control” through this equipment, Its test chamber is used as a commonly used testing equipment in fields such as aviation, automobiles, home appliances, and sci...
There are many different brands of color spectrophotometers on the market, and even within the same brand, there are multiple products available. The handheld and desktop types are the most popular categories, but what are the differences between these two types? Portable Colorimeters – also known as Portable spectrophotometers Can directly read data and connect to a computer through softwa...
I. Introduction of Surge Generator Surge generators are important equipment in electrical systems. Their main function is to simulate high-voltage pulses or instantaneous voltage fluctuations to test and evaluate the effectiveness of different surge suppression systems. These high-voltage electrical devices mainly serve to prevent transient voltage fluctuations from damaging electrical systems, th...
