Introduction Accurate spectrum measurements and the characterisation of light sources and materials are often performed using high precision spectroradiometer integrating sphere systems. Maximizing the light’s dispersion inside the integrating sphere is an essential part of these setups. This article delves into the connection between the integrating sphere’s light distribution and the...
In recent years, with the rapid development of automotive services, vehicle fires have become a serious problem in safe traffic. Due to the small space, high degree of sealing, dynamic driving and other characteristics of vehicles, once a fire occurs, it is difficult to control, which will seriously endanger the life safety of passengers on board. Therefore, the flammability of Interior materials ...
Introduction When conducting tests and experiments on materials, goods, and electronic components in a controlled environment, temperature and humidity chambers are indispensable instruments. Regular calibration of temperature and humidity chambers is essential for obtaining repeatable and trustworthy test results. Here, we’ll learn about the value of temperature and humidity chamber calibra...
The Needle Flame Test is the main test item for testing whether electronic products and materials are inflammable. It simulates the flame generated by overheating of electronic products and components under fault or overload conditions, thus realistically reproducing the existing situation and evaluating the fire hazard of the product by simulation technology. This paper analyzes the requirements ...
Introduction: When testing electronic components and systems for performance and reliability, electrostatic discharge (ESD) guns are necessary. While the ESD gun is the primary tool, there are a number of add-ons that can expand the range of tests that may be performed, increase the precision of measurements, and provide more varied test configurations. This article delves into the many ESD gun ad...
The rapid temperature change test chamber is used to test the performance of various materials in various environments, such as heat resistance, cold resistance, dry resistance, and moisture resistance. It is suitable for testing the quality of products such as “electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemistry, building ...
I. Introduction: Testing for electromagnetic compatibility (EMC) is crucial to creating safe and compliant products. EMC testing has always been done in dedicated labs using large, costly equipment. However, mobile EMI test receivers have made on-site testing easier and more accessible. This article will discuss the advantages, characteristics, and practical uses of portable EMI test receivers, as...
I. The purpose of the dust test chamber The dustproof test chamber, also known as dustproof grade test equipment, is suitable for the dustproof test of welders, electronic equipment,electrical products, automotive lamps, motorcycles, chemical plants and other parts and materials, and then check the sealing performance of the goods’ shell protection level GB4208-93 IP5X/IP6X dustproof test. S...
High temperature chamber is mainly used for high-temperature experiments in industrial and mining enterprises, laboratories, scientific research institutions, etc. It has the functions of drying and sterilization. I. Core advantages of high temperature chamber: 1. With multiple overtemperature protectors: ①. The temperature controller stops heating and there is no heating signal output. ②. If ...
