Portascanner® WATERTIGHT PRO

Ultrasonic Watertight Integrity Quantification Instrument

Portascanner® WATERTIGHT PRO is a handheld, tablet-based integrity testing system that is able to detect the exact location and size of multiple leaks simultaneously on a single structure. Portascanner® WATERTIGHT PRO records leak flow rate and location to its database and can export these to a USB to record and report the test results electronically.

Specialist Digital Leak Identification

Portascanner® WATERTIGHT PRO allows an operator to photograph a test site before testing which then allows the operator to plot the exact leak location allowing for easy repair and reinspection. Portascanner® WATERTIGHT PRO also calculates the flow rates of individual leaks as well as an overall leakage rate for a single hatch and can relate these rates to compliance requirements for watertightness and weathertightness.

It requires minimal training and a single operator can non-invasively test a large number of hatches or seals consecutively. This makes Portascanner® WATERTIGHT PRO a highly accurate and easy-to-use way of ensuring marine safety and regulatory compliance.


Adaptable and Optimisable

Portascanner® WATERTIGHT PRO can be widely applied to different hatch or room sizes and its system can be adapted for optimum operation by choosing different equipment options or settings:

  • Variable power single transducer ultrasonic generator for precision applications.
  • Triple transducer generator for wider-range applications.
  • Generator tripod stand for better propagation in large cargo holds.
  • Ability to filter test records by date or location to ensure easy processing of results.
  • 2 test modes (quick test and full test) to streamline testing process depending on operational requirements.

Frequently asked questions

The Portascanner® WATERTIGHT PRO has the highest accuracy of any leak quantification instrument of its kind. Our in-house experiments have demonstrated a high level of accuracy (within ±10%) in leak-size quantification, which has been independently verified by the National Physical Laboratory. Flowrate accuracies are subject to user error in input measurements such as seal thickness and roughness, as well as the shape of the leak, however, our empirical formulae are calibrated to the upper error bound, so you can be sure that the true waterflow rate will not significantly exceed the calculated value.
No, the Portascanner® WATERTIGHT PRO can be used with people in the room, as long as they do not directly interfere with the test (i.e. standing directly between the generator and receiver).
To some extent, yes, however the application will guide the operator through finding an optimal position for the generator. Generally, though, the generator should point directly at the structure to be tested, positioned with transducer approximately centred on the structure at a distance of between 0.5 and 5 metres.
No, it does not matter, the test should be performed from whichever side is most convenient and practical. For example, if the operator is testing a door that leads onto a corridor, we would suggest placing the generator inside the room and performing the measurements from the corridor so as not to obstruct the full width of the corridor.
Yes, there is no complicated equipment required for a test, just the generator and the hand-held Portascanner® WATERTIGHT PRO unit. In the case of an emergency, the operator may simply leave; all that may happen is the generator will use battery power and may need to be recharged.
Currently, a USB drive is required to export the reports. This will be included in the package; however, any USB drive can be used.
