The UV Aging Test Chamber adopts fluorescent ultraviolet lamp as the light source to simulate the ultraviolet radiation and condensation in natural sunshine, and carries out the accelerated weather resistance test to obtain the result of the material weather resistance. It can simulate the environmental conditions such as ultraviolet, rain, high temperature, high humidity, dew condensation and darkness in natural climate. By reproducing these conditions, combining them into a cycle and letting it automatically execute the number of cycles. LISUN UV aging test Chamber is designed for evaluating the resistant performance of non-metallic materials, organic materials (plastics, paints, coatings, rubbers, etc.) under the specified conditions such as sunlight, temperature, and other climatic conditions. It creates a man-made testing environment imitating the natural light source such as sunlight and other damages in the nature, such as rain and dew damage, to impose on the materials and to...

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...
