There are six factors that affect the color measurement of the colorimeter, each of which plays a crucial role in the way the colorimeter captures color information. Any change of these factors will change the color data, resulting in differences between the numbers obtained by two identical samples or two different colorimeters. 1. Color space: In terms of color, there are many measurement system...
To evaluate a product’s shell sealing ability by the International Protocol for the Testing of Shells, the “Dustproof test chamber” is utilized to mimic the detrimental effects of natural sand, dust, and wind conditions (IP5X and IP6X). It is sometimes referred to as a dust and sand test chamber. The SC-015 dust-free test chamber has a vertical airflow and uses a conical hopper; ...
GLE-20 is an oil-salt two-in-one Face Masks Particulate Filtration Efficiency PFE Tester. According to ASTM F1862-17, ASTM F2299-03 (2017), ASTM F2100-2019, BS EN14683-2019, BS EN 14387-2004+A1 2008, BS EN 136-1998, BS EN 140-1999, BS EN 143-2000 +C1-A1, BS EN 149-2001+A1, etc. It is used to test the particulate filtering efficiency of daily protective masks and medical masks, and to dete...
Semiconductor Solid Lighting (SSL) is a trend of future development, especially today, where global energy is becoming increasingly tense and the climate is deteriorating today. With the application of electronic integrated technology in LED products, the trend of miniaturization of LED lamps and can only be modularized can become increasingly obvious. More and more LED products have begun to ente...
The North American Lighting Engineering Association (IESNA) has recently published the LM-82-12 standard test method. This test method can measure the relationship between the electrical, optical characteristics and temperature of LED light engine and LED light bulb in the working state. The new standard provides a consistent test method to help lamp manufacturers choose LED light engines and inte...
The colorimeter is used to measure the color difference between two samples. It is a high-tech product integrating colorimetry, modern optoelectronics and computer science. Accurately Measure Color Causes of color difference: 1. Light of various wavelengths will be dispersive to varying degrees. When white light is dispersed into various wavelengths of ultraviolet, visible and infrared wavebands, ...
Waterproof test chamber can also be called rain test box, waterproof test machine, waterproof test device, etc. It tests various waterproof grades of products by simulating the natural rain environment. The main purpose of the waterproof test chamber is to detect the product, and judge whether the product performance meets the requirements through the verification after the test, so as to facilita...
Transparency is one of the important indicators to evaluate the optical properties of transparent film, but during the production process of transparent film, due to the stability of production processes, the optical performance of transparent film will change. In order to accurately evaluate the optical properties of the transparent film, you can use the haze meter to test. Transparent film The n...
We know that the main purpose of the research and development of chroma meter is to detect the color of products and control the color quality of products. To better analyze and manage color information, it is necessary to understand the color. The change of color is closely related to color. To learn color, we should first know what the three primary colors are. The chroma meter detects the produ...
