The RoHS t...
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. Standard: Full meet the EN13032-1 clause 6.1.1.3 goniophotometer type 1, COMMISSION DELEGATED REGULATION (EU) 2019/2015, CIE-70, CIE-121, IES LM-79, IES LM-7...
The salt spray test chamber mainly deals with the surface treatment of various materials, including paint, electroplating, inorganic and surface film, anodizing, anti-rust oil and other anti-corrosion treatments, and then testing the corrosion resistance of its products. Electroplating can be done according to customer requirements the parts and products are subjected to salt spray test. Preparati...
The temperature and humidity environmental chamber can simulate a variety of temperature and humidity natural environments, and is suitable for testing electronic devices, household appliances, food, trolleys, vulcanized rubber, plastic rubber, metal materials and other commodities. So how does the temperature and humidity environmental chamber carry out humidification? The whole process of humidi...
Spectroscopy is a method of identifying substances and determining their chemical composition and relative content based on their spectra. It is an analytical method established on the basis of molecular and atomic spectroscopy which called spectroradiometer. Contains three main processes: ①energy provides energy; ②energy interacts with the measured substance; ③produces the detected signal. ...
Goniophotometer is mainly used to measure the spatial distribution of light intensity and color space of lamps, and output various measurement reports according to the test report: When a lamp is lit, its light output in the 4π space with the lamp as the center of the sphere is not exactly the same, that is, the light intensity value of each point on a certain spherical surface is different. For ...
The salt spray test is divided into two categories, one is the natural environment exposure test, and the other is the artificial accelerated simulated salt spray environment test. The artificial simulated salt spray test is to use a kind of test equipment with a certain volume space-the salt spray test chamber, in its volume space, artificial methods are used to create a salt spray environment ...
When you check the RoHS test compliance, It must be noted that the analysis values of x-ray fluorescence light provide information on the presence or absence of controlled substances in elemental form. Must pay special attention to such as Cr and Br, the result is total Cr and total Br, and does not reflect the form of its existence. Therefore, if Cr and Br are present, hexavalent chromium, PBB, P...
The integrating sphere is a cavity sphere coated with a white diffuse reflection material on the inner wall, also known as a photometric sphere, a luminous sphere, etc. One or several window holes are opened on the spherical wall, which are used as light inlet holes and receiving holes for placing light receiving devices. The inner wall of the integrating sphere should be a good spherical surface,...
