That is easy to carry on travel luggage and benefits your overseas travel plans.

Controlling the roughness of a ship’s hull plays an important role in the operating costs of a vessel. The roughness of a ship’s hull increases mainly due to corrosion, pitting, plate undulation, mechanical damage, dry spray and above all bio fouling. Proper maintenance and the correct application of high-end anti-fouling coatings reduce the hydrodynamic effects. And it also will lead to significant savings on fuel consumption and CO2 emissions.

The hull roughness gauge can measured during in-docking and out-docking.

The Hull Roughness Gauge measures the AHR value (Average Hull Roughness) of sea going vessels. AHR is vessel’s hull roughness readings, and the measure against ship’s correlated performance.

The TQC Hull roughness Gauge consists of a Control unit and a Sensor unit.
The unit easy to operate, only with one hand and a 4-way directional push button operates an intuitive menu on a large illuminated display. The neck strap keeps the users’ hands free when required.

Sensor equipped with three non-slip wheels, a carbide tipped stylus and is moved over the ship’s hull in a horizontal way collecting series of measurements. A set of LED’s indicate the status of the instrument so operation is possible without observing the control unit.

Available statistics, time/date and also location of each series. Control unitare will automatically calculated and stored the average hull roughness. Using the supplied USB-cable and software you instantly create inspection reports in Microsoft Excel. Available Your company logo and details incorporated stiles in your reports.
