Electromagnetic disturbance that degrades the performance of electrical equipment or electronic device, works abnormally or fails. It can be divided into conducted interference test and radiated interference test. EMI Test Standard: EMI test standards for electronic products can be classified according to different types of products: Industrial, scientific, medical: CISPRI1, EN501, GB4824, YYO505-...
Photometry is a method that estimates the concentration by measuring wavelengths of light of organic and inorganic compounds in a solution. Photometric measurement is critical for water quality management when heavy metals, pesticides, and more are detected. The quality management and development of lighting in a human context are essential for photometric measurements. This includes all displays,...
Lighting surge generator provides a common basis for evaluating the resistance of power cords and internal connectors of different equipment to high energy transient interference caused by natural lightning surge induction and large capacity load switching. It fully meets the IEC 61000-4-5, EN61000-4-5 and GB/T17626.5 standards. Here we talk about the surge generator working principle. 1. The basi...
Goniophotometer is a device used to measure the light distribution performance of lamps. Goniophotometer measures the spatial light intensity distribution of lamps or light sources, total luminous flux and lamp efficiency and other parameters. Goniophotometer need to work in larger darkroom. Use low-reflectivity materials in the room to avoid reflected light from entering the probe. Depending on t...
A goniophotometer is a test device that measures the amount of light emitted from a light source when seen from various angles. The term goniophotometer is derived from the words goniometer, which is used to measure angles. And other words photometer is used to measure light. The goniophotometer gadget is equipped with the same technology as the goniometer. To determine the quality features of the...
Having a surge generator ensures you have enough electricity in case of emergencies or power disruptions. The issue develops when your generator stops working properly. Thankfully, power surge generators are quite communicative and will let you know if something is wrong and needs repair. Why does a generator surge? Inappropriate fuel use, poor maintenance, age, a failing capacitor, or other ccomp...
Photometers and spectrophotometers instruments are well-suited and well-established for measuring moisture, oil/fat, and other easily distinguishable parameters in a wide range of applications. spectrophotometer derived from these photometers. Photometers are usually used to measure parameters at certain wavelengths where the parameter absorbs light, such as 1.94 microns for water and 1.72 micron...
Radiometry professionals may be familiar with the theories of light and color measurement; the equipment used to detect light and color. The instrument for such calculations includes radiometer, spectrometer and spectroradiometer. However, all three devices can measure light and energy. Therefore, the capabilities, intended uses, and applications of radiometers, spectrometers and spectroradiometer...
A goniophotometer is a device used to determine the amount of light emitted by an item at various angles. The usage of goniophotometers has increased in recent years due to the advent of LED light sources, which are predominantly directed light sources with a non-homogeneous spatial distribution of light. If a light source’s distribution of light is homogenous, it is referred to as a Lambert...
