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.  

Haze measurement can be distorted by scratches on the surface, dust, temperature, and light. 

Take L*a*b* readings of two samples using a colorimeter or spectrophotometer and calculate color difference using the 3 formula (Delta E). The difference in 0 is the reported Delta-E, which shows how visible the change is, whereas the thresholds define the acceptability as per the application requirements.

Colorimeters or spectrophotometers are used to measure liquid color. They measure light coming through or reflecting off the liquid. Readings can be reported as Lab*, RGB, or absorbance units. So that objective color analysis can be used to control quality, or to measure chemical concentration.

Always a pre-production sample before mass production; Always final Inspection before shipment; 

To ensure a consistent color perception, observers should look at samples at a 45° light angle and 0° viewing angle to reduce glare.

At most of time, we have Spectrophotometer stock in the factory. Generally it is 1-3 working days after the payment confirmed. After shipped, we will email you the tracking number. You can check the shipping status of your order on the website. If you are in urgent need, we can consider making special arrangement for you.

The Colour Assessment Cabinet (CAC) is a controlled environment used for the visual evaluation of color wherein the light sources are consistent.

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