Hitachi - CMI155 & CMI157

Handheld Coating Thickness Gauge

Hitachi - CMI155 & CMI157

Using dual technology to measure coating thickness on non-ferrous and ferrous metal substrates.

Technical Description

  • Measuring Coating Thickness on Non-Ferrous and Ferrous Metal Substrates
  • Quickly test paint, lacquer, and other protective coatings on metal substrates.
  • Dual technology ensures accurate measurements upon contact.

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:

Key Features:

  • One-button operation
  • Factory-calibrated
  • Automatic substrate detection
  • Integrated probe design
  • IP52 dust and water protection
  • No operator training required

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.
