    What is a Gloss Meter Used for?

    Gloss meter is an instrument used to measure the surface gloss of ceramics, paints, inks, plastics, marble, aluminum, hardware and other materials. High-precision gloss meters are classified into three types according to the angle, including high-gloss, medium-gloss and low-gloss. As a professional instrument for detecting the gloss of the external surface of objects, the gloss meter is widely used in chemical raw materials, paint manufacturing, aerospace industry, automobile industry, shipbuilding industry, electronic industry, electrical industry, IT communication, etc. Now we will talk about gloss meter application in several different areas.

    How to Calibrate Gloss Meter?

    Every time we use the gloss meter, we must first calibrate the gloss meter. The purpose of calibration is to eliminate the influence of changes in the intensity of the light source and environmental changes each time the machine is turned on. This step of calibration is very important. If the calibration is not done well, the measurement will be greatly affected. Therefore, during the calibration process, it is necessary to ensure that the bottom surface of the gloss meter and the calibration plate are in very close contact. So how to calibrate gloss meter?

    Gloss Meter Basics

    Gloss is a physical quantity that evaluates the ability of a material surface to reflect light under a set of geometrically specified conditions, with directional selective reflection properties. The gloss we usually say refers to mirror gloss, so the gloss meter is sometimes called mirror gloss meter. Gloss is quite different from the machining industry's concept of finish or roughness, which is a continuation of the tiny unevenness on a material's surface.

    How to Choose a Gloss Meter?

    Gloss meter, as known as gloss tester, is used in gloss measurement for paint, marble, ceramic, plastic, metal, etc. Gloss meter is widely used in chemical raw materials, paint manufacturing, aerospace industry, automobile industry, car maintenance, floor polishing, electronics, electrical appliances, IT communications and other industries. But how to choose a gloss meter?

    How Many Measurement Angles does the Gloss Meter Have?

    At present, the common gloss meters on the market mainly include 20°, 60° and 85° measurement angles. Different measurement angles are suitable for surfaces with different glosses. For industries such as paper, 45° and 75° measurement angles are used. Due to the different measurement angles, the gloss values we measure on the surface of the object are different. In order to accurately assess the surface gloss of the object, it is necessary to choose a gross meter with a suitable measurement angle.

    How to Detect the Surface Gloss of Lime-Glaze with Gloss Meter?

    Lime glaze is a commonly used glaze in the production process of traditional lime glaze ceramic. Due to the difference in raw materials and calcination process, the appearance and color of lime glaze will be different. In order to verify the surface gloss of lime glaze, a gloss meter can be used to measure. The lime glaze uses calcium oxide as the flux, and the glaze whose molecular number of calcium oxide should account for more than half is the lime glaze.

    Difference between 60° and 20° of Gloss Meter

    Gloss meter is an instrument used to measure the gloss on the surface of paint, paper, plastic, furniture, ceramics, enamel, marble, rubber, ink, leather, diamond and various fabric products. Gloss meters with different measurement angles are suitable for different items. Gloss can be divided into 3 general ranges, including low gloss, semi gloss and high gloss.

    Why You Need a Gloss Meter?

    Gloss is an attribute of the surface of an object. The specular reflection ability of its surface to light can be measured by gloss, and the unit of gloss is generally expressed by GU. So, why measure gloss? How to use a gloss meter to measure it? There are no more than two methods to detect the glossiness of objects, one is the visual observation method and the other is the instrument detection method.
