Of course! Many portable, battery operated, and lightweight coating thickness gauges are available for on-site and field inspections. They provide quick and accurate results and portable gauges are ideal for construction, automotive, and industrial environments.


An 80 gloss surface will reflect less light as compared to a 100 gloss surface. Both are said to be high gloss, although 100 GU (or higher) reflects almost as much as a mirror. The distinction can be slight in graphic terms, but major in specific uses.


Yes, we warmly welcome and sincerely invite you or your team to visit our factory, we will help to arrange hotel and pick up you from airport.

Measuring zinc coating thickness is most commonly using magnetic induction. The gauge measures how far the magnetic probes are to the metal base under the zinc. This is the most reliable way to measure the thickness and the preservation of the galvanization.

An inappropriate viewing angle may lead to reflections or color shifts in the light. The correct angle of 45 or 0 will provide the real color of the assessment without the distraction of glare.

A colorimeter is a quick and inexpensive method to measure color and to control color in a material or solution. It is used to maintain color consistency during production and to check the chemical concentration. It also assists with the quality control of labs, food, textiles, and pharmaceuticals.

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


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.

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.
