Description

Gloss Meter.

Gloss meter is an instrument which is use to measure specular reflection gloss of a surface. It is determin by projecting a beam of light at a fix intensity and also angle onto a surface. And then measuring the amount of reflected light at an equal but opposite angle.

There are a number of different geometries available for gloss measurement. Each being dependent on the type of surface to be measured. For non-metals such as coatings and plastics the amount of reflected light increases with a greater angle of illumination. As some of the light penetrates the surface material. And is absorbed into it or diffusely scattered from it depending on its colour. Metals have a much higher reflection and are therefore less angularly dependent.

Many international technical standards are available that define the method of use and specifications. For different types of glossmeter used on various types of materials including paint, ceramics, paper, metals and also plastics. Many industries use glossmeters in their quality control to measure the gloss of products. This to ensure consistency in their manufacturing processes. The automotive industry is a major user of the glossmeter. With applications extending from the factory floor to the repair shop.

PosiTector GLS Gloss Meter.

What is gloss and why is it important to measure?

Gloss meter PosiTector GLS is an optical property that indicates how well a surface reflects light in a specular (mirror-like) direction. It refers to how lustrous or shiny an object appears, generally affecting its aesthetic and perceived value. Gloss measurement is useful for identifying process issues and defective parts—maximizing consistency, reducing waste, and improving quality.

Measuring a product gloss can improve the production process by identifying process issues, maximizing consistency, reducing waste, and improving overall quality. Surface texture, coating properties, and paint application can all have an effect on a coating’s appearance. While it’s easy for the human eye to detect large differences in gloss, like comparing a matte finish on a military asset to a glossy red sports car, smaller differences in gloss can be harder to see—but can still have a big impact on process control.

Measuring Gloss with the Gloss Meter PosiTector GLS.

Gloss is impressive, that can be seen in almost every industry from automotive, electronics, and also baby toys. No matter what is the industry the gloss tends to be associated with luxury and also wealthy. Studies suggest that humans’ innate love for glossiness could be based on the biological need for water: the glossier an object, the more likely to ‘quench thirst’.

From an industry standpoint, gloss can have a very specific purpose. By definition, gloss is an optical property that indicates how well a surface reflects light in a specular (mirror-like) direction—or, how lustrous or shiny an object appears. While many industries prefer a glossier finish, some require a more matte finish.

What is Reflectance?

Reflectance is a measurement of the amount of light detecting versus the amount of light sent, and is express as a percentage. Gloss meters such as the PosiTector GLS can display in both GU and percent reflectance directly on the gage.  When light hits a surface, some of it is absorb, and some is reflect. The reflected light is responsible for how the object is perceived. The nature of the reflection is generally related to the surface finish of the object. On a smooth polished surface like a mirror, light is reflected opposite to the angle at which it arrives; this is referred to as ‘specular’ reflection. On a rough surface, light is reflecting at all angles and a relatively small amount of light reflects at the specular angle

What is Gloss Value? What are Gloss Units?

Per ISO 2813, Gloss Value is a ratio of the reflectance of the test specimen to the reflectance of a standard polished black glass surface “with a refractive index of 1,567 at a wavelength of 587.6 nm in the specular direction”, multiplied by 100, and it is expressed in terms of Gloss Units.

What is Haze Index?

Haze is the appearance of a “milky” halo or bloom perceived in reflective surfaces caused by microscopic imperfections in the surface’s texture. Haze Index is calculated and is defined by ASTM D4039 as the difference between gloss values measured at 60° and 20°. The PosiTector GLS 20/60 and 20/60/85 are capable of calculating haze when selected within the Setup menu.

How is Gloss meter PosiTector GLS Measure ?

Digital gloss meters like the DeFelsko PosiTector GLS Gloss Meter measure the surface using a calibrated light source and light sensor at opposite, specular angles to each other. Reflectance is determined by the amount of light energy emitted by the source comparing with the amount of energy received by the sensor. Gloss will automatically calculated using a look-up table.

The PosiTector GLS Gloss Meter includes a reference standard built into the base of the unit. When turning on the unit the instrument automatically calibrates itself using the known Gloss Unit values of the standard.

Choosing the Best Angle for Gloss Measurement.

On most surfaces, as the viewing angle increases, the reflectance and Gloss Value also increase. This is often apparent to the naked eye, and for example on the case below. There is a little apparent reflectance when viewed from above. But we will see the visible reflectance when the same case is view from a wider angle. This phenomenon can be use to provide greater measurement resolution on high-gloss and matte finishes.

TQC Gloss Meters.

The TQC Gloss meter designed for measure of gloss levels on any flat surface in fast, and also simple accurate . Whether it be on paper, paint, plastic, and wood, or any other material appearance. Without special training or skills requirement, only place the gauge, then press the scan button and read the values. Template options can also provide non-flat surfaces and small test areas.

Two models are available:

TQC SOLOGloss.

The Solo of 60° singe-angle instrument TQC SOLOGloss meter range is preferrin for measurements in the semi-gloss range. It,s suitable for most applications, such as light source and also detector are positioning under an angle of 60° from the surface to be measure.

TQC POLYGloss.

The best of the TQC -Gloss meter range is the triple angle instrument PolyGloss. Besides a 20° and 60° measuring angle, the TQC PolyGloss is also equipped with a 85° measuring angle thus covering the entire gloss-spectrum . The 85° is for low gloss levels ( high diffuse reflection ) or mat surfaces.*
