Coltraco Watertight Integrity Testers are of Huge Benefit to the Marine Industry

Coltraco is successful in producing ultrasonic technology to cater for 19 markets. The Portascanner® Watertight ensures that your ships and systems are weather and watertight. This solution is available as a product or in constant monitoring system.

Portascanner® Watertight monitors watertight, airtight or weather-tight. When it comes to cable transit areas watertight testing whereas considered appropriate for scuttles, shell doors, hatch – covers, doors, flanges and steering gear hatches are the few others; this device has accuracy of up to 0.06 mm. Coltraco has manufactured and produced this range keeping the requirement of modern needs.

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:

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

Technical Features of Portascanner Watertight

Here below are the technical specifications for receiver and generator, which you want to know:

Technical Specifications - Receiver

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

The receiver of this ultrasonic leak detector 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.

Portascanner Watertight is designed 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.

Technical Specifications of Portascanner’s Generator

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

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 vessel 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,
