Gloss measurement is conducted using a gloss meter, also known as a glossometer, which is an instrument designed to measure the surface specular reflectance (gloss). Gloss is determined by projecting a beam of light onto a surface with fixed intensity and angle and measuring the amount of reflected light at an equal but opposite angle. The method of gloss measurement is based on the principles of ...
In 2020, a global outbreak of the pandemic resulted in a shortage of protective equipment such as masks, primarily due to the scarcity of one of the main raw materials, melt-blown fabric. As a consequence of the melt-blown fabric shortage, some individuals began attempting to produce their own, leading to varying qualities of melt-blown fabric products in the market. Against the backdrop of intens...
The particle filtration efficiency tester is a specialized instrument used to assess the filtration efficiency of products such as air purifiers, masks, and automotive air purifiers. Its role is to ensure that these products effectively filter out harmful particles and gases from the air, thereby protecting people’s health. The principle of the particle filtration efficiency tester is based ...

In the field of electronic testing, digital bridges play a vital role. Traditionally, digital bridges were primarily used for measuring parameters such as inductance, capacitance, resistance, and impedance, a practice considered conventional. While early impedance measurements indeed utilized traditional bridge methods, the advent of modern analog and digital technologies gradually phased out this...
What is Ground Resistance? Ground resistance refers to the resistance encountered by current flowing from the grounding device into the earth and then dispersing to another grounding body or to the distant area. It includes the resistance of the grounding wire and grounding body itself, the contact resistance between the grounding body and the earth, as well as the resistance of the earth between ...
Corrosion testing is widely employed in quality assurance laboratories within the metal industry as a critical step in quality control testing. These tests are typically conducted in salt spray test chambers, covering a range of tests for black metals and alloys. Additionally, corrosion testing is also carried out in the paint and coating industry to ensure the quality of coatings, thereby extendi...
With the rapid development of modern industrial technology, the application of electroplated products is becoming increasingly widespread across various fields. However, the complex and diverse environmental conditions also place higher demands on the quality of electroplated products. The sulfur dioxide test chamber, as a critical piece of equipment, plays an important role in accelerating the co...
