Yes, 3nh has a wide sales and service network worldwide, we provide overseas service through our authorized distributors or service partners located in Western Europe, Northern and Southern America, and the Asia-Pacific. 

The color of chemical products is measured by using a colorimeter or spectrophotometer. The instruments measure the amount of light that gets absorbed or reflected by a substance. It may be used to determine concentration, purity, or compliance with product standards.

Spectrophotometer, Colorimeter, Gloss meter, Haze Meters, Coating thickness meter, window tint meter, UV meter, Leeb hardness tester, Light booth, Color Test Chart, Ultrasonic thickness gauge. Threenh Technology company adheres to independent design, research and development, production and sales of various measuring instruments. 

To determine haze, haze meters are used in multiple industries such as plastic, glass, film, coating, and displays. This ensures that all optical quality of the product is in the appropriate specification, including aesthetic compliance and meeting the intercontinental quality standards.

Use our 3nh company approved light. Replace all of the same type together and recalibrate to keep consistent color rendering. We usually do not recommend customers to modify it themselves, as this can affect the accuracy of the color and cause unnecessary losses

When using a Pantone light box, each sample should be positioned flat and nearby the other samples, but not overlapping. Each one should also be in the middle of the light box, and the surfaces of the light box should be clean and non-reflective.

There is no generic mathematical formula for gloss value. Rather, it is measured directly with a gloss meter, which compares how strongly reflected light from a sample matches a standard (typically black glass with a known reflectance).

Our machine is packed by standard export wooden box, it won’t be damaged. We’ve delivered many testing machines abroad by sea or by air without damage.

For a proper color evaluation, ensure cleanliness, use standardized observation conditions, eliminate stray light, and periodically change the lamps.

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.
