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.

Depending on model and location, delivery time is usually 2-4 weeks for standard models and 4-6 weeks for built- to-order ones. 

Techniques of measuring color are visual color comparison, colorimetry (with colorimeters) and spectrophotometry (measuring spectral reflectance), and image analysis. Both techniques measure the reflection or absorption of light by materials and are commonly quantified. Therefore standardized in color spaces such as CIELAB or RGB.

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.

Samples should be cleaned, dried, and scratched-free to obtain consistent haze measurements.

A digital coating thickness gauge is used to measure the thickness of dried paint. It measures coating thickness specification non-destructively, helping to maintain consistent quality and performance.

1. Turn on the hazemeter and check if the instrument’s display screen shows normally and if the buttons are responsive.

2. Verify that the hazemeter’s battery power is sufficient. Replace the battery or connect an external power supply if necessary.

3.  Confirm that the instrument’s measurement mode is set correctly. Select the appropriate measurement unit and range based on actual needs.

Color evaluation will change based on how a sample is viewed.  A 45° viewing angle to the source is recommended to reduce shading and achieve consistent comparison.

The LAB color space defines colors in a three-dimensional model: Lightness (L), red–green axis (a), and blue–yellow axis (b). It's a globally recognized standard supported by most modern color measuring devices. CIELAB is a standardized, device-independent system designed to map all visible colors that the human eye can perceive.

The LAB color space uses three values to define any color, each representing a specific dimension:

L (Lightness): Ranges from 0 to 100. It measures the brightness of the color, where 0 is pure black and 100 is pure white.
A (Red-Green Axis): Ranges from approximately -96 to +127. Positive values represent red tones, while negative values represent green tones.
B (Yellow-Blue Axis): Ranges from approximately -96 to +127. Positive values represent yellow tones, while negative values represent blue tones.

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.
