Safer, Faster, and More Efficient Testing

Portamarine® offers a cost-effective solution for inspecting marine fire suppression systems. Using proven ultrasonic technology, it delivers highly accurate results—within ±1.5 mm—for most CO₂, Halon, and Clean Agent systems. Its non-invasive, portable design means a single operator can test an entire bank of cylinders of different sizes and agents without dismantling or weighing them. This streamlined process ensures quick, reliable measurements with zero downtime for the fire suppression system, allowing crews to perform checks safely and efficiently.

Eliminating Downtime and Reducing Risk

Because Portamarine® does not require cylinders to be disconnected or dismantled, it eliminates the risk of accidental discharge during testing. When paired with the Portasteele® CALCULATOR, operators can convert liquid-level readings into precise agent weight, removing the need for physical weighing. This combination provides a faster, safer, and more efficient way to meet marine safety standards such as IMO SOLAS FSS Code and MSC.1/1318.

Built for Marine Applications

Portamarine® is engineered specifically for the demands of the marine industry:

  • Durable design with a backlit LCD screen for clear operation in low-visibility marine environments

  • Wide compatibility with CO₂, Halons, and Clean Agents for comprehensive fire suppression monitoring at sea

  • Extension rod included for easy access to banked cylinders without system disruption

  • Portable and handheld, powered by standard AA batteries for convenient transport and extended use without recharging

  • Approved by RINA Classification Society, ensuring compliance with marine safety standards

Why Monitor Fire Suppression Systems?

Fixed fire suppression systems protect critical infrastructure and assets. They rely on high-pressure cylinders filled with agents like CO₂, FM-200™, NOVEC™ 1230, and Halons. Over time, cylinders can leak, so regulations require checks every 6 months to ensure proper agent levels.
