Coating Weight Gauge
The Industry Standard In Coating Weight Gauging
The Coating Weight Gauge
The Global Gauge Coating Weight system is capable of measuring various metallic coatings such as zinc, tin, aluminum, etc. The principal of operation is to direct an x-ray beam into the coated material. The x-ray energy level is sufficient to fluoresce the steel substrate under the coating.
By measuring the intensity of the “backscattered” radiation, the thickness of the coating can be determined. This system contains dual digital heads, which can be provided using proportional counter or ion chamber detectors. Each head houses all necessary components for coating measurements. The lightweight digital heads use only fiber optic lines for communications. Large cable bundles are eliminated. Heavy duty linear slides are used to transport the heads.
This system is extremely accurate, cost effective, and dependable.
