Each haze test can take from 3 to 10 seconds depending on the device and the type of sample.

Look for dirty or fingerprinted glass along the optical path, recalibrate with standards, and check the set-up for outside light so that it is controlled. If the problems still exist, please reach out to the helpdesk or book a service with your professional service.

Make sure the light sources are calibrated, keep extraneous light sources away, have the correct viewing angles, and handle the samples in a clean and uniform manner.

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).

A colorimeter sends light through a solution and measures the amount that is absorbed. It computes the absorbance by comparing the intensity of light before and after passing through. The greater the concentration of the color, the greater is the absorption of the light. It is also possible to quantify the color of the solution.

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. 

To keep a neutral background, helping to reduce color distortion and bias.

The color may be quantified in L*a*b* (CIELAB units), RGB values, CMYK (printing), and ΔE (color difference). Colorimetric assessment measures also apply spectral reflectance and absorbance (A), particularly in liquids and solutions.

A paint gloss meter is used to measure the level of paint gloss, whereby it reflects light at some angles, such as 20°, 60°, or 85° angles, and measures the intensity of that light. To measure surface sheen, the level of gloss is compared to standards that are calibrated and reported in units of gloss (GU).

Assembling the light booth entails connecting the panels, fixing the light fixtures, fitting the tubes, and calibrating the lights according to our 3nh manufacturer’s instructional and safety guidelines.
