The Portalevel® MAX Marine is the ideal tool for any Marine Servicing companies who are testing very large volume of cylinders or when testing more specialized agents onboard such as FM200® and NOVEC 1230®.

For any vessel or servicing company having to deal with the common time pressures of having to measure very high numbers of onboard fire suppression cylinders, especially CO2, the Portalevel MAX Marine provides the ideal tool. Often during annual certification, there is significant time pressure on completing the inspection of every cylinder accurately in order to ensure this critical piece of safety infrastructure is fit for purpose. To address this need, the Portalevel MAX Marine® has been designed to inspect cylinders incredibly fast. By reducing the time required to inspect each cylinder, crew members and Servicing companies alike can complete the task quickly and efficiently.

The package comes with a slimline extension rod, just 12mm wide, which can slip between the cylinder banks and check the 2nd, 3rd or 4th rows of cylinders easily, without having to remove any tanks from the manifold. This method also completely removes the need for weighing cylinders which is an incredibly time consuming and dangerous method which can often result in damage to the system during inspections.

With full Type Approval by ABS & RINA, the Portalevel MAX Marine is also capable of inspecting a variety of other clean agents such as FM200® and NOVEC 1230® as regularly found onboard more advanced modern vessels.
