Fast, Accurate, and Portable Coating Measurement
Product Overview
Coating Thickness Handheld Gauges are high-performance, user-friendly instruments designed to deliver non-destructive coating thickness measurements quickly and accurately on a variety of substrates. These compact and durable devices are ideal for on-site quality control, process monitoring, and field inspections, helping operators ensure compliance with industry standards.
With models like the CMI155, CMI157, CMI165, and CMI233, Hitachi offers specialized solutions for both ferrous (magnetic) and non-ferrous (non-magnetic) base materials, supporting a broad range of coating applications such as paint, plating, anodizing, and galvanization. Their simple operation, ergonomic design, and robust construction make them a reliable choice for professionals across diverse industrial environments.
