Maritime Water Testing Kits

Regular drinking water testing is essential to ensure the safety and compliance of your onboard water supply. Any deviation from expected values may indicate contamination risks or system malfunction, requiring further corrective actions.

Routine testing helps maintain compliance with flag state requirements, maritime sanitation regulations, and your vessel’s Water Safety Plan (WSP)—critical whether you operate regionally or worldwide.

Our test kits are equipped with a unique water testing parameter set that is designed to meet the most common maritime health regulations and sanitation standards.

However, every vessel’s requirements differ. Additional parameters may be necessary depending on:

• Flag state instructions
• Route-specific water risks
• Requirements listed in your Water Safety Plan
• Recent port operations or bunkering locations

For tailored guidance, our team can help identify which kit best suits your operational area and compliance needs.

Onboard testing measurements are taken directly at the tap.

This is why our kits use handheld meters that are portable, fast, and reliable – allowing crew to assess water conditions wherever needed on board.

 If you’re unsure which method or kit fits your vessel type or region, we’re happy to walk you through the setup.

If any reading is outside compliance limits:

• Refer immediately to your Water Safety Plan (WSP)
• Follow procedures defined by your flag state
• Consult us for recommended corrective steps

Onboard parameters act as indicators. For example, low chlorine levels may signal a potential biological risk, in which case a confirmatory laboratory test is highly recommended.

If you need help interpreting results or deciding on next steps, our specialists can offer practical guidance.

We do not recommend biological testing on board due to the complexity of incubation, handling, and result interpretation.

A certified and accredited laboratory is required for reliable microbiological analysis.

For most vessels, routine onboard indicator testing combined with scheduled laboratory sampling ensures full compliance and safe drinking water quality.

No. Accredited laboratory reports remain mandatory to stay in compliance with maritime drinking water regulations.

Onboard test kits play a complementary role:

They provide continuous insights, help detect early deviations, and support safe operational practices between laboratory sampling intervals. This means you’re audit-ready and will never be caught out in a surprise.

The right kit depends on:

• Your flag state and route
• Required parameters
• Crew experience
• Desired level of accuracy and automation

More advanced kits, such as our Expert Kits, offer higher precision, require less manual work, and function as effective water management tools for busy crews or vessels operating across multiple regions.

• WATERLAB Manual: Manual, visual, no digital interface — ideal for simple checks.
• WATERLAB HADEX: Digital, designed for total control of your HADEX levels.
• WATERLAB MLC: Designed for MLC and aligned regulatory compliance with digital reporting.
• WATERLAB Expert: Comprehensive, advanced monitoring with broader parameters, connectivity, and data management.

If you’re not sure which level of testing suits your vessel, we can help assess your operational needs and regulatory requirements.
