Skyrocketing costs of metal coating materials such as zinc have driven the need for improved process control. Anything other than the optimum coating thickness is unacceptable either from a quality control or cost control standpoint. The time has come for a fast, nondestructive, and accurate method of measuring coating thickness and coating weight, and analyzing plating bath solution. Handheld x-ray fluorescence (XRF) offers general metal finishers and others the advantage of at line testing, eliminating the need to cut samples and spend valuable time taking the sample to a benchtop analyzer to wait for results. 尼通（NITON）XL5手持式合金分析儀
