To take care of a haze meter to make it last longer, ensure that it is cleaned, recalibrated regularly, and stored in a dry, dust-free place. 

A powder coated surface is most commonly measured for thickness post curing using a digital coating thickness gauge. This method is non-destructive, helps verify coverage uniformity and meets quality control standards. A powder comb gauge is used to estimate thickness for a pre-cured coating.

Record the L*a*b values of the sample and the reference with a calibrated spectrophotometer or colorimeter. Compute the difference in the color by use of ΔE. The lower the Delta E, the more accurate the result. The difference in energy, ΔE < 1, is generally assumed to be invisible to the eye.

Every 2,000 - 3,000 hours or manufacturer recommendation to maintain consistent light and color quality.

To answer this question, you first need to clarify your specific needs: 

• Is it for simple color quality control (QC)?

• To coordinate with supply chain color management?

• To monitor on-line color stability?

• Do you require computer color matching or production color correction?

• What is your budget?

• Systematic supervision and evaluation of color performance in dyed products?

If you aren’t fully clear about your requirements at the initial stage, our color management engineers are ready to communicate with you. We will recommend solutions tailored to your needs. When conditions permit, we can provide prototype demonstrations and trial testing to ensure the instrument meets your practical application requirements.

Haze captures the scattering of light, transmittance measures the light that passes through a said material.

The accuracy of colors is determined by comparing the values of the colors (L*a*b*) of a sample with a standard reference sample using tools such as spectrophotometers. The variation is measured as ΔE. The smaller the value of ΔE, the more accurate, the nearer to the target color.

You should not attempt measuring on surfaces that are dirty, oily, or rough, as these surfaces will not provide an accurate reading. Always calibrate the paint thickness tester and make sure to select the proper probe for the substrate as well. Proper execution will bring about consistency as well as trustworthiness to the readings.

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 haze meter measures the light.  It quantifies the measure of transmitted light across a material and the degree of scattered and diffused light.
