What are the coating Thickness Gauges suitable for measuring the thickness of the coating in explosion-proof occasions?

Abstract: 本文讨论了适用于防爆场合的涂层测厚仪。由于电子测厚仪通常依赖电池供电，不适合防爆环境，推荐使用机械式涂层测厚仪。例如，麦考特的EPK MikroTest Ni100、S10、NiFe50和G6型号及Defelsko的PosiTest G和F型号都是适用于非电子、防爆场所的选择。这些机械式仪器通过磁感应或直接物理接触测量涂层厚度，无需电源或电池，符合防爆要求。文章还列出了这些仪器的具体规格和性能参数，以便选择合适的型号。

In the chemical industry, there are many flammable and explosive products in some environments, so the requirements for explosion protection are relatively strict, including the use of testing instruments. So are there any coating Thickness Gauges that are suitable for explosion-proof scenarios?

The current coating Thickness Gauges are basically electronic Thickness Gauges, which are generally powered by batteries, so as long as there are batteries, they must be non-explosion-proof. If you want to be explosion-proof, you must choose a non-electromechanical Thickness Gauge, such as the well-known McCourt coating Thickness Gauge, which uses the principle of magnetic attraction for thickness measurement, so it is more suitable for testing in non-explosion-proof environments.

What brands and models of mechanical coating Thickness Gauges are there? We compiled a list for you, as follows:
