Inconsistent results from a haze meter can stem from issues like calibration, dusty haze meter optics, inadequate power supply, and improper measurement technique. If you have any questions, you can contact our Haze measurement experts

Color is a qualitative and quantitative measure. Qualitatively, it can be characterized by the hue, the saturation, and the brightness. It is quantified in terms of color spaces, such as L*a*b* or RGB, in terms of numerical values based on devices such as colorimeters or spectrophotometers.

Now our testing machines have been sold to more than 80 countries, like USA, Canada, Russia,UK, Italy, Germany, European , India, Pakistan, Philippine, Singapore, Malaysia,Thailand , Vietnam, Korea,Saudi Arabia,Brazil...and so on. We sell to the global market.

With centers in 20 countries, including India, Japan, USA, Germany, Singapore, China, South Korea, and Taiwan, Threenh Technology’ s service network aims to provide customers with convenient access to service globally. With over 1 million measuring instruments sold, our expertise is our greatest asset, enabling us to work with our customers on solutions to complex measurement challenges.

Testing metamerism helps to identify color matches that look the same but are different in different lighting. This helps in ensuring that materials are of the same quality in all light settings.

Light should be projected through the sample to measure haze, then assess the scattered light with an integrating sphere and sensors.  The haze percentage is ascertained by the scattering light to the total transmitted light.

Ensure the source, viewing angle, and background are all neutral and standardized, and the samples are clean, and positioned for a side-by-side comparison under each light condition.

A magnetic induction gauge measures galvanized coatings by sensing the zinc coating on steel and iron. The measurement tells how thick the protective coating is. This is done to ensure the prevention of rusting.  

Yes. Ultrasonic coating thickness gauges can pinpoint layers within a multi-coat system. Users can examine the separate thicknesses of a primer, base coat, and clear coat. In contrast, magnetic and eddy current gauges usually measure the overall thickness of the coating. 

Gloss level is not given out in percentage but in gloss units (GU). In practice, however, 100 GU is considered 100 percent reflective. To contrast visually, the 20-40 GU is a low-gloss surface, and 85 or more is almost 100 percent mirror-like reflection.
