LISUN ZY-3 Needle flame test LISUN ZY-3 is a needle burner of a specific size (0.9mm) and gas (butane or propane). Burn test at 45° intervals at regular and directed inte...
Surge generators are useful in running tests on electrical components of products and gadgets. the surge generator working principle helps understand how the device runs tests and helps understand the results. In this article, we investigate the history of surge generators with the advancements in this technology and how LISUN is being a part of this legacy. LISUN Surge generator The SG61000-5 is ...
There are a number of corrosion tests that may be used to determine the long-term durability of protective coatings. However, the focus of this article is on the Salt spray test. This test creates a corrosive attack on coated samples in order to determine the coating’s fitness for application. This article will help you learn how to utilize and apply the salt spray test. LISUN’s Salt s...
If your application requires measurement of a widely diverging beam, an integrating sphere is the best option to consider. An integrating sphere is an optical component that captures a light beam and enables you to measure the power in the beam under conditions that would otherwise be very challenging. A widely diverging beam that might overfill a regular sensor aperture. Sphere integration LPCE-2...
As more and more household appliances enter our daily life, and people use these electrical products more frequently, this requires that in addition to the design of household appliances to meet the requirements of people’s use, the safety design of the electrical appliances and the use environment must be more in line with people’s needs. 1. Reference Standards GB 16915.1 “Switc...
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...
