I. Surge Test Equipment Standard The national standard for surge voltage tester is GB/T17626.5 (equivalent to the International Standard IEC61000-4-5). The standard mainly simulates various cases due to indirect lightning strikes, such as: (1) lightning strikes on external wires, resulting in a large current flowing into the external wires or ground resistance, thus generating interference voltage...
High and low temperature humidity test chamber is a scientific experiment equipment for simulating various environmental conditions. It can simulate temperature and humidity conditions in real environment, helping people to verify products with high performance, safety and durability. GDJS-015B Temperature Humidity Chamber | Thermal Chamber The control system is the heart of the whole equipment, w...
Introduction As we move towards a more sustainable future, lighting designers are more concerned with developing ecologically friendly and low-energy lighting options. Sustainable lighting design relies heavily on goniophotometry, a precise measuring method for assessing the angular distribution of light. Focusing on its effect on energy efficiency, light pollution reduction, and human-centered li...
We know that CIE (International Commission on Illumination) is the most authoritative organization in the colorimeter industry. Basically, the chromaticity space and color difference calculation formula used by Colorimeter are all launched by CIE. The CIE Lab, CIE RGB, and CIE XYZ that we are currently familiar with are all color difference instrument spaces launched and continuously improved by C...
I. Definition of Glow Wire Test The Glow Wire Tester is used to test the stability of electronic appliances when working. The hot thread itself is actually a fixed-specification resistance wire loop. During the test, the hot thread needs to be heated to a predetermined temperature by electricity, so that the top of the hot thread can be contacted with the sample to meet the standard requirements, ...
Why is the constant temperature humidity chamber blocked? 1. During the test, the door was opened, and there was icing in the working room. 2. The dryer is aging and fails, and the drying and water absorption function is lost. 3. When the cryogenic compressor is pressurized for leak test, the water in the air is condensed into water droplets and injected into the pipeline, resulting in ice blockag...
Dustproof Test Chamber is a specialized instrument used to assess and measure a device or equipment’s ability to withstand penetration, abrasion, or obstruction by dust particles. Its primary function is to evaluate the reliability and maintainability of a variety of mechanical, optical, electrical, electronic, mechatronic, and electrochemical devices in a sand blast, dust storm, and dust de...
Introduction To make sure that textiles and clothing last and are comfortable to wear and functional, the fast-paced textile and apparel sector must use rigorous quality control methods. Manufacturers may simulate and analyze the impact of climatic conditions on textile materials with the help of temperature and humidity chambers, which have become an indispensable tool in this sector. In this art...
In the field of product development, electromagnetic compatibility (EMC) research has become increasingly important. Many engineering departments hope to have their own EMC testing environment. In the EMC test, the radiation launch measurement of the product is particularly important for the test environment and equipment. The environment for radiation launch requirements is an open field (OATS) o...
