Metric Thickness Gauges for Ship Maintenance & Survey

Our metric thickness gauge is an essential precision instrument for marine surveyors, ship engineers, and maintenance crews. It delivers reliable ultrasonic thickness measurements of steel hulls, deck plating, and structural members, helping to assess corrosion wastage and ensure vessel integrity. With clear digital readings in millimeters, this gauge streamlines routine inspections, dry docking surveys, and class society compliance checks.

Built for tough shipyard conditions, the gauge features a robust enclosure, a backlit LCD for easy viewing in dim spaces, and simple one-hand operation. Non-destructive testing means you can measure plate thickness without damaging the coating or the substrate. Whether you work on offshore platforms, cargo vessels, or tugs, this thickness gauge is your practical partner for preventive maintenance and structural health monitoring.

Each unit includes a calibration certificate and a durable carrying case. Long battery life and automatic power-off provide worry-free operation on every voyage.

Frequently Asked Questions

What is the measuring range of this thickness gauge?

The gauge measures from 1.0 mm to 200 mm in metric units, making it suitable for most ship steel plate thickness measurements.

How does the gauge perform measurements?

It uses ultrasonic technology, emitting high-frequency sound waves through the material and measuring the time for the echo to return, providing a precise thickness reading without damaging the plate.

Is a calibration certificate included?

Yes, each gauge is supplied with a calibration certificate traceable to national standards.

Can it be used on painted or corroded surfaces?

The gauge is designed for use on smooth and lightly corroded metal surfaces. For best accuracy, clean or grind the test area before measuring.
