The high and low temperature environmental test chamber is also called the high and low temperature cycle test, which is one of the product environmental reliability tests. Basically all products are stored or operated under a certain temperature environment. In some environments, the temperature will constantly change, sometimes high and sometimes low. For example, the temperature in day and nigh...
When the dustproof test instrument fails, stop heating. After the test is completed, first turn off the operation switch, and then turn off the main switch. The air temperature should be kept high enough. Below is Lisun’s dustproof testing machine to specifically introduce the “ What need to pay attention to for dustproof tester”. Precautions for dustproof tester: 1. When the internal dustpr...
The high and low temperature environmental chamber is formed by CNC machine tools, the humidification system pipeline is separated from the control circuit board, and the water system pipeline circuit system is convenient for maintenance and repair. The following is a specific introduction to the “box structure and fault description of the high and low environmental chamber“. Structure...
The functions of the optical integrating sphere tester include light receiving, uniformly illuminated object surface, spherical parallel light tube, etc. Its principle is that after light is incident from the input hole, the light is uniformly reflected and diffused inside the sphere. Below take Lisun’s optical integrating sphere system as an example to introduce it in detail. The role of op...
The lightning surge generator adopts semiconductor electronic switch technology, the waveform is smooth, the output is accurate, supports the judgment of the failure of the sample, and provides a buzzer alarm to ensure the consistency of the surge combination wave. The below is Lisun’s lightning surge generator as an example to introduce it in detail. Features of lightning surge generator: 1...
Goniophotometer is mainly used to measure the light distribution performance of lamps and light sources, that is, the luminosity and color measurement value distribution of the laser source of the lamp in different directions in space. Goniophotometer test system. It is mainly divided into two types: horizontal and vertical. It is mainly used to test the lumens, light distribution curve, glare lev...
