Diversity that comes with Coltraco’s Watertight Integrity Tester

Portascanner watertight is the portable Ultrasonic watertight integrity indicator – for testing watertight and weather-tight seals. It is ideal for checking the hatch-covers, doors, scuttles, cable transit areas, shell doors, flangers, steering gear hatches etc. Designed primarily to enhance the ease and accuracy with which critical airtight, watertight or weather tight seals can be inspected for leak sites or areas of reduced compression in the seal.

Features Offered with Ultrasonic Hatch Cover Tester

  • Three years warranty
  • Lifetime Support
  • Calibration and Training certificates available
  • Identifies leaks as small as 0.06mm +/-0.02 mm
  • Non-intrusive ultrasonic technology
  • 10 hours battery life
  • No fuss setup
  • Magnetically mountable
  • Class approved

Accuracy of Results Obtained

The extent of the leak is indicated by the numerical readout by this hatch cover maintenance and watertight integrity testing device. In terms of the numerical readout:

  • “0 - 5” or ”0 dB” indicates seal watertight integrity
  • “6 - 100” or “1 dB - 26 dB” indicates weather-tightness only
  • “101+” or “27 dB+” indicates weak seal compression
  • High values indicate a full leak site

Technical Specifications of Portascanner’s Receiver

  • Output:  1 watt (maximum) audible signal (via calibrated headphones with visual 4 digit LCD display and graph)
  • Size: 21.5cm x 8.5cm W x 3.5cm H
  • Weight: 419 Grams
  • Powered By: 1 x 9V PP3 batteries with low battery indication
  • Battery Life: 10 hours continuous use minimum
  • Enclosure: Aluminium IP65 Waterproof

The receiver of this hatch cover tester uses ultrasonic technology to convert the 40KHz pulses sent by the generator into three easily comprehensible readings: audible, bar graph and numerical which enables the operator to understand if the seal is wholly watertight or to what extent a leak exists.

Technical Specifications of Portascanner’s Generator

  • Output:  0.1 watt/100dB unidirectional
  • Mounting Arrangements: Permanent Magnet
  • Size: 15cm L x 9cm W x 5cm H
  • Weight: 431 Grams
  • Powered By: 2 x 9V PP3 batteries
  • Battery Life: 10 hours minimum
  • Enclosure: ABS material

The generator is an ultrasonic generator with three transducers. This will produce a strong signal in one direction i.e. directly from the transducer which fills the compartment being tested with ultrasound pulses e.g. providing sufficient coverage to fill the hold when the hatch-covers are closed. The generator is permanently fitted with a powerful magnet which allows it to be attached to the vesselʼs structure where required. A magnet cover is provided when the magnet is not in use.

CEO Message

Integrity and Science Key to Our Culture of Performance

Dear Coltraco Customers, Strategic Partners and Distributors,

Integrity is our defining value. Performance is its consequence. We understand that our customers have choices, and how we perform determines whether customers choose us. Coltraco’s Code of Ethics does not merely require compliance with laws. It embodies a Commitment to positive behaviours that build trust, promote respect, operate with distinction, with courtesy and global levels of performance, demonstrating our integrity and delivering customer performance.

We honour our commitments, communicate transparently, and act with honour. Ethics are the foundation of our performance culture and our science-based approach. We lead in specific technologies delivering the watertight integrity monitoring of marine structures and the monitoring of fixed liquefied gaseous fire extinguishing systems and the room integrity of protected space to ensure agent hold-times post-installation. We show this by our understanding of the science in them and the mathematics that explain them.

I would like to thank you for your business and for the relationships with our Customers, Strategic Partners, Distributors and ODAs who we value so highly.

My kindest regards,
