Our hull roughness gauges represent the next evolutionary step in hull roughness surveying and have been taking the marine industry by storm.
They’re relied upon across the seven seas by ship operators, ship builders, ship repairers and coating manufacturers.
The hull roughness increases with corrosion, pitting, plate undulation, mechanical damage, dry spray and biofouling. Monitoring the roughness of a ship’s hull plays an important role in controlling the vessel’s operating costs.
Proper maintenance and the correct application of high-end anti-fouling coatings reduces the hydrodynamic effects. This offers significant savings on fuel consumption and CO2 emissions.
Our hull roughness gauge is easy to operate with a four-way directional push button. It offers you graphical representations; you can store data in multiple batches and analyze reports in Microsoft Excel®.
The whole system fits conveniently into a small rugged, waterproof case. It can be carried as travel luggage which simplifies any overseas travel plans considerably.
A hull’s roughness is measured during in-docking and out-docking. Our device quickly measures the AHR value (average hull roughness) of sea going vessels.
Control our hull roughness control unit with just one hand. Plus its neck strap keeps your hands completely free when required.
The sensor unit is equipped with three non-slip wheels and a carbide tipped stylus. This moves horizontally over the ship’s hull while collecting precise measurements.
Statistics including the time, date and location of each series of tests, plus the average hull roughness, are automatically calculated. Your results are stored in the control unit and can be used to create instant inspection reports in Microsoft Excel via a USB-cable. You can even add company logos and other details to create bespoke reports.
We’ve made products for the marine industry for many years now and like to share our hull roughness expertise. Why not check out our blog that compares two variables of common roughness / smoothness testers?
Although it’s robust in design, our hull roughness tester is a precision engineered instrument…so keep it safe from knocks and drops! Here’s some simple advice on how to keep it in ship-shape condition for years to come:
Always clean the hull roughness gauge after use with a soft, dry cloth
Never use abrasive cleaning methods such as wire brushes, abrasive paper or aggressive cleaning agents. And don’t apply compressed air either.
Keep the instrument in its case when not in use
We recommend annual calibration.
Keep out of the sun, excessive light exposure and humid environments
Don’t use in very high or low temperature environments
Switch off the hull roughness gauge before adjusting any electric component.
