Enhance Quality Control with the MiniTest Series

Erichsen’s MiniTest series provides state-of-the-art solutions for non-destructive measurements of coating thickness. These advanced gauges are designed for precision and versatility, offering accurate thickness measurement of non-magnetic layers such as paint, plastic, chrome, and other galvanic, non-magnetic layers on ferromagnetic substrates like steel and iron. Additionally, they are capable of measuring insulating layers on conductive substrates, including aluminium, copper, titanium, and austenitic stainless steel, across a broad range of measurement settings.

The MiniTest series is engineered to meet the demands of industries requiring exact precision in coating thickness to ensure the quality and longevity of their products. By leveraging these tools, businesses can significantly enhance their quality control processes, allowing for the fine-tuning of product finishes, adherence to international standards, and ultimately, increased customer satisfaction.
