The TQC Hull Roughness Gauge has made the next evolutionary step in hull roughness surveys. Surpassing the industrial standards with an easy to operate 4-way directional push button, graphical representations, storage of data in multiple batches and survey reports in Microsoft Excel®. The whole system fits into a small sized waterproof rugged casing that is allowed as 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 biofouling. Proper maintenance and the correct application of high-end anti-fouling coatings reduce the hydrodynamic effects and will lead to significant savings on fuel consumption and CO2 emissions.
The hull roughness is measured during in-docking and out-docking. The Hull Roughness Gauge measures the AHR value (Average Hull Roughness) of sea-going vessels. AHR is the ‘mean’ of all the vessel’s hull roughness readings and is the measure against which ship’s performance is correlated.
The TQC Hull roughness Gauge consists of a Control unit and a Sensor unit.
The Hull Roughness Control unit can be operated with just one hand, 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.
The Sensor unit is equipped with three non-slip wheels and 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.
Statistics, time/date and location of each series and the average hull roughness are automatically calculated and stored in the Control unit. Using the supplied USB-cable and software you instantly create inspection reports in Microsoft Excel. Your own company logo and or -details can be incorporated to restyle your reports.
Accuracy: +/- 5 microns or or Memory: Enough for 4 complete surveys done both in- and out-docking, totally over 10.000 readings
Location storage: Simply point and click the hull location in the displayed graphical representation of the ship’s hull.
Units: Microns
Speed: 50 mm/s, with speed indication LED in the Sensor unit
Interface: USB serial to PC connection
Power supply: 4 AA type Alkaline Cells, available worldwide
Calibration certificate: included
The TQC Dust Test Kit according to ISO 8502-3 allows assessment of the quantity and size of dust particles on surfaces prepared for painting. Dust on blast cleaned surfaces can reduce coating adhesion, leading to premature coating failure and sub-standard coating finish. The dust test kit can be used in accordance with the recommendations of BS EN ISO 8502-3 either as a pass/fail test or as a permanent record of the presence of dust.

The TQC Surface Profile & Coating Thickness gauge is a combination gauge. that can be equipped with two different tips, one for surface roughness and another for coating thickness.
Supplied with a sharp tungsten carbide replaceable tip for surface profile measurement, a hardened round tip for coating thickness measurement, a glass plate for zero calibration and a leather carry pouch that fits all items.
The TQC Sheen surface profile roughness gauge is a simple instrument for ultrafast measuring of the point peak-to-valley height of a surface. The shape of the base makes this instrument ideal to measure the height of welds.
