CT-Gage Thickness Gauge

The CT-Gage

The CT-Gage has been designed as a muli-purpose ultrasonic material and coating thickness instrument with a wide range of features.

The CT-Gage is able to simultaneously and independently measure the material and the coating thickness, or switch to the time based B-scan view to see a cross section view of the material you are inspecting.

There are 5 Measurement Modes:

• Pulse-Echo
• Pulse-Echo w/coating
• Echo-Echo
• Pulse-Echo w/temperature compensation
• Coating only mode

The CT-Gage is easy to use incoporating:

• Single or two-point calibration option for material and coating, or selection from basic material types.
• Automatic Probe Zero
• Automatic Probe Recognition
• Automatic temperature compensation
• Automatic gain control
• Time corrected gain

A custom calibration configuration for both the material and coating types offers extreme linearity.

The CT-Gage DL includes all of the above features but is also equipped with a data logger. The data logger consists of two file formats: Sequential logging with auto identifiers and an alpha-numeric grid. The file formats are currently compatible with Ultra-Pipe Asset Management Software.

The CT-Gage DL can store 16,000+ readings, with B-Scan captures, recording all the gauge's settings and features, or turn the graphics mode off and store of 210,000 readings!
