Spectrophotometer is a color measuring instrument with excellent performance, wide use, and easy operation. This instrument is suitable for color detection and color difference control of complex products in industry, such as measuring the reflected and transmitted colors of objects, while also measuring the whiteness, chromaticity, and the most basic color difference between two objects. The spectrophotometer is designed to provide a 45 °/0 ° geometric viewing angle suitable for human eye observation. It displays the reflectance and transmittance of a single object in the visible light band of 300nm-700nm, and is connected to a computer through an interface to expand more functions. At the beginning of the development of spectroscopic colorimeters, researchers generally consider configurations suitable for different industries, products, and measurement environments, including the selection of light sources (A, C, D65, D50, and so on), and a variety of color difference formulas to c...

The core component of the ozone aging test chamber is an ozone generation device. The general principles of ozone generation include electrochemical method, corona discharge method, and ultraviolet method: 1. Electrochemical method: a method of producing ozone gas by electrolysis of oxygen-containing electrolytes using a DC power source; Ozone produced by electrolysis has the advantages of high concentration, pure composition, and high solubility in water, which will have a good application prospect. 2. Corona discharge method: Simulates the method of ozone generation by natural lightning, and generates corona in the gas through artificially alternating high-voltage electric fields. The free high-energy ions in the corona dissociate O2 molecules and polymerize into oxygen molecules through collision. 3. Ultraviolet method: Artificial ozone production uses photoelectric method to generate wavelength λ= The ultraviolet spectrum of 185 nm (10-9 m) is the most easily absorbed by oxyg...

The IK spring impact hammer is a tool used to test the protection level of electrical equipment enclosures. According to the International Electrotechnical Commission (IEC) standards, the IK level system is classified based on the degree of impact the equipment can withstand. This article will analyze in detail the IK level impact test standard for the IK spring impact hammer. I. Definition of IK Level IK level refers to the degree of impact the equipment enclosure can withstand during testing. There are a total of 11 levels from 0 to 10, with higher numbers indicating higher impact resistance of the equipment. II. IK Level Testing The IK level testing of the IK spring impact hammer consists of two parts: impact test and rating. The impact test evaluates the ability of the equipment enclosure to withstand impact by using the IK spring impact hammer. The rating assigns the equipment to the appropriate IK level based on the results of the impact test. III. Impact Test The IK ...

What is an EMC Test Chamber? EMC Test, also known as Electro Magnetic Compatibility (EMC), stands for Electro Magnetic Compatibility, referring to the comprehensive evaluation of the size of electromagnetic field interference (EMI) and anti-interference ability (EMS) of electronic products, which is one of the important indicators of product quality. The measurement of electromagnetic compatibility is composed of the test site and the test instrument. Therefore, the EMC test box is a powerful carrier in this test. What is Electromagnetic shielding cabinet? Electromagnetic shielding cabinet, referred to as EMC Room, is a dedicated room with electromagnetic shielding function used to shield harmful electromagnetic wave interference material, thus tackling electromagnetic interference technology. It is also used for testing the electromagnetic interference performance of the equipment and verifying the electromagnetic compatibility performance of the related products in such an indo...

This is an outdoor lighting and street light factory located in Switzerland. The customer learned about our company’s High Precision Rotation Luminaire Goniophotometer through our website. After understanding the type and maximum size of the lights the customer needed to test, we recommended a model that suited their needs, and after confirming some technical details, the customer immediately placed an order to purchase our LSG-1800A High Precision Rotation Luminaire Goniophotometer. Upon receiving the customer’s order, our engineers started designing the floor plan of the darkroom based on the room dimensions provided by the customer. The darkroom is an environment that provides no external light sources to ensure the accuracy and reliability of the measurements. Utilizing their expertise and experience, our engineers created a detailed floor plan, indicating the placement of the lighting fixtures and the photometer, and selecting appropriate materials and dimensions to ensure the ef...

In industrial production, when testing electronic components, it is necessary to use a High and Low Temperature Thermal Shock Chamber for detection and testing. It is used for temperature cold and hot impact testing. The time for temperature conversion is short and the change is fast, so that the temperature impact of product testing can be achieved. Under ultra-high and ultra-low temperature conditions for a period of time, chemical changes or physical damage caused by thermal expansion and contraction of the product are detected for a short time to determine the quality of the product. The High and Low Temperature Thermal Shock Chamber is composed of an equipment chamber, an air circulation system, a refrigeration system, and a control system. In addition, it is divided into three areas: high temperature, low temperature, and shock testing. The wind circulation system generally adopts an adjustable wind direction structure; The air conditioning refrigeration structure forms a tempe...

I. Standard for Surge Generator of Electronic Devices The national standard for electro-equipment surge generator is GB/T17626.5 (equivalent to international standard IEC61000-4-5). II. The standards for lightning surge generator mainly simulate various situations caused by indirect lightning strikes (1) When lightning strikes the external line, a large amount of current will flow into the external line or the ground resistance, resulting in interference voltage. (2) Indirect lightning strikes (such as lightning between clouds or within clouds) induce voltage and current on the external line. (3) When lightning strikes near objects, a strong electromagnetic field is set up around it, which induces voltage on the external line. (4) When lightning strikes near the ground, interference is introduced when the ground current passes through the public grounding system. III. In addition to simulating lightning strikes, the standard also simulates interference induced by switch act...
