Dakota CX4 Material Thickness Gauge

Overview

The Dakota CX4 Material Thickness Gauge is a professional handheld ultrasonic instrument engineered for accurate material thickness measurement when access is available from only one side. Part of the Dakota CX Series, the CX4 incorporates features and functionality suitable for a wide range of industrial and maintenance workflows, including corrosion monitoring, fabrication quality control, and routine inspection tasks. 

Based on proven ultrasonic Pulse Echo (PE) technology, the CX4 delivers dependable thickness readings across metallic and rigid non-metallic materials such as steel, aluminum, glass, and plastics. The gauge supports multiple measurement modes, including Pulse Echo, Echo Echo ThruPaint™, and Velocity Mode, enabling inspectors to measure thickness on both coated and uncoated surfaces. 

Enhanced calibration options provide greater flexibility and measurement accuracy compared to entry-level units. The intuitive interface and ergonomically designed housing ensure usability in field and workshop environments, supporting daily inspection routines with minimal setup time.

Measurement Capabilities

The CX4 supports multiple measurement modes, enabling it to handle a variety of inspection scenarios:

• Pulse Echo (PE): Standard ultrasonic thickness measurement across a wide thickness range. 

• Echo Echo ThruPaint™ (EE): Measures material thickness even through coatings without removal, reducing inspection preparation. 

• Velocity Mode (VM): Allows users to adjust sound velocity for specific materials to improve measurement accuracy. 

Selectable reading resolution and user-definable limits for high/low results further enhance the gauge’s effectiveness in identifying potential areas of material loss. 

Typical Industrial Use

The Dakota CX4 is commonly used in inspection and maintenance applications such as:

• Corrosion and wall thickness monitoring on pipes, tanks, and vessels

• Material thickness verification during fabrication and installation

• Routine thickness checks in power, petrochemical, marine, and heavy industries

• Facility maintenance programs requiring repeatable and consistent thickness measurement

FAQ

What are the main measurement modes supported by the Dakota CX4?

The CX4 supports Pulse Echo (PE), Echo Echo ThruPaint™ (EE), and Velocity Mode (VM) for flexible and accurate thickness measurement across coated and uncoated materials. 

Can the CX4 measure through coatings without removal?

Yes. Using the Echo Echo ThruPaint™ mode, the CX4 can measure material thickness through coatings up to the specified range without the need to remove protective layers. 

Is the CX4 suitable for use on metals and non-metals?

Yes. The gauge is suitable for a wide variety of substrates, including steel, aluminum, glass, and plastics. 

Does the CX4 include onboard data logging?

No. The CX4 focuses on real-time measurement and does not include extensive internal data storage; data logging features are available in higher-end models like the CX8-DL. 

What environments is the CX4 designed for?

The CX4 is designed for industrial field and workshop use, with rugged construction and a user-friendly interface suitable for daily inspection tasks.
