An integrating sphere makes it easy to measure samples. Integrating sphere measurements can be taken for different samples. This article will explain integrating sphere and the processes of taking measurements using LISUN’s Integrating sphere. Integrating sphere The Ulbricht sphere is another name for integrating sphere. The Ulbricht sphere takes after Richard Ulbricht. He is a German engin...
Salt spray test chambers is that your fasteners are put in, you rely on their endurance and want them to remain serviceable at all times. When it comes to corrosion testing, a salt spray test is a technique that employs high-salinity settings to determine the corrosion resistance of items, paints, and coatings over a prolonged period. A salt spray tester does this test. Tests for corrosion resista...
The strength or quantity of light that a light source can produce is known as light intensity. The light intensity is the amount of power produced by the light source. Its measurement unit is the Candela or Cd. A particular measurement equipment is required to determine this intensity. One such instrument is the Goniophotometer. This article will see how a goniophotometer can be used as an instrum...
1. What is a thermocouple? 1.1 Introduction to Thermocouples Thermocouple (thermocouple) is a temperature measuring element commonly used in temperature measuring instruments. It directly measures the temperature, converts the temperature signal into a thermoelectromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument (secondary instrumen...
What is the LED test standard？ Semiconductor light-emitting diode (LED) is a new type of light-emitting body, with high electro-optical efficiency, small size, long life, low voltage, energy saving and environmental protection, it is an ideal lighting device for the next generation. LED photoelectric test is an important and only means to test LED photoelectric performance, and the corresponding...
In addition to producing a negative influence on the sensitive electronics that underlie the guidance and communications systems of today’s military vehicles, sand and dust may also have a negative impact on the tough exterior that serves to shield those components from harm. This test is performed in a dust test chamber or dust tester. Sand and dust testing have become an essential element ...
It is well known that color table and color rendering are two important quantities that reflect the color of light sources. Light sources with different spectral power distributions can have the same color table, but the color rendering properties of several light sources with the same color table may be completely different. Therefore, only the combination of color table and color rendering can f...
1. What are the prevention and control plans and standards for juvenile myopia? 1.1 Adolescent myopia prevention and control program: With the increasing rate of myopia among teenagers, more and more students are becoming shortsighted. In order to protect the children’s eyes and let them have a bright future. Eight ministries and commissions including the Ministry of Education and the Nation...
Let us first attempt to comprehend what the RoHS test is and why it is seen to be significant in the first place. RoHS is an abbreviation that stands for Restriction of Hazardous Substances at its core. The Directive 2002/95/EC is sometimes referred to as the 2002/95/EC. Because it is a descendant of the European Union, it is structured only to restrict the application of some hazardous substances...
