Coating Thickness Gauges are commonly used to measure the thickness of paint on the surface of a material. Measurement of coating thickness can be used to assess the life expectancy of coatings, the appearance and performance of products, and ensure compliance with many international standards.
In some coating applications, such as high-temperature coatings on cast iron surfaces, special high-temperature surface coating Thickness Gauges are required for measurement. High-temperature coating thickness measurement solutions are widely used in foundry industry, electroplating industry, coating industry, automotive industry, aerospace and shipbuilding, etc. This article introduces several domestic and imported Thickness Gauges that can be used for high temperature thickness measurement.

| Product Series | measurable temperature | Measuring range |
| Defelsko with FHXS high temperature probe | 250°C | 0~10000μm |
| EPK with high temperature magnetic probe | 350°C | 0~2000μm |
| Defelsko Pen Thermal Spray Coating Thickness Gauge | -100~230℃ | 5~500μm |
| An Miao High Temperature Thickness Gauge | 200℃ | 0~1250μm |
Finally, there is another alternative solution, that is, the probe of the Thickness Gauge produced by PHYNIX in Germany can wear a high-temperature cap ring, which can measure hot surfaces with a temperature of 300 °C.
