1. The mechanism of EFT Immunity Measurement and its impact on electronic products The EFT immunity tester is a transient disturbance generated at the disconnection due to the insulation breakdown of the switch contact gap or the contact bounce when the inductive load (such as relay, contactor, etc.) is disconnected. When the inductive load is repeatedly switched on and off for many times, the pul...

What is the goniophotometer？ The goniophotometer is the main measuring equipment for the light distribution performance test of lamps, which can be used to measure the spatial light intensity distribution, total light flux and lamp efficiency of lamps or light sources. The goniophotometer system consists of precision turntable and control system, spectrum analysis system, standard lamp, alignmen...
Origin and development of integrating sphere: The use of integrating sphere in measuring luminous flux can be traced back to 1890, and now it has become a widely used instrument in many aspects. The integrating sphere can be used to test the luminous flux, color temperature, light efficiency and other parameters of the light source. It is an indispensable instrument in the measurement of radiance,...
I、 Purpose of environmental test The environmental test examines the adaptability of the product to the environment, determines whether the environmental adaptability design of the product complies with the contract requirements, and provides decision-making basis for acceptance and rejection. A. Quantity of environmental stress used for environmental test In terms of environmental test, 19 te...
Salt spray testing Salt spray testing simulates a corrosive salty environment in the laboratory. It is used to speed the testing of surface coatings’ capacity to withstand air corrosion. It is one of the oldest testing procedures used in the HVAC-R coatings business and, as such, is frequently referred to when selecting HVAC-R coatings. YWXQ-010_Salt spray Test chamber The utility The salt s...
GTS-LS The GTS-LS glare measurement system uses an image luminance meter with great precision. Testing UGR, TI, and GR used in indoor and outdoor light pollution tests is a good idea. Through a precise electronically controlled pan and tilt and specialized measurement and control software, the high-precision measurement and analysis of the unified glare index UGR is made possible. The system is co...
