Using dual technology to measure coating thickness on non-ferrous and ferrous metal substrates.
The CMI 155 and CMI 157 measure the thickness of a single layer or the total thickness of coatings applied to iron, steel, aluminum, and other metals. With probe tips designed for smooth surfaces and an extended measurement range, these devices are ideal for:
These compact handheld gauges are factory-calibrated and automatically select the best measurement technique for the base material. The durable design includes a rubber housing and meets IP52 environmental protection standards, making them suitable for use in harsh conditions.
