Portable Gas Detectors

Our award-winning range of portable gas detectors provides customers with a simple, reliable and stress-free approach to safeguarding personnel against a wide range of hazardous gases.

Unlike fixed gas detectors, which permanently monitor a designated area, portable gas detectors are mobile devices used by personnel to provide pre-entry gas level checks.
Each portable device will test gas levels in an area to ensure it is safe for human entry.

The focus on three core pillars reflects that of our customers – ship safety, performance and crew welfare, so we know we tick all portable gas detection boxes.

Mobile Portable Gas Detection Range

Portable gas detectors such as the Marine 4 & 5™, Triple-C or the Protégé ZM can be worn by crew members to check that various spaces are safe before they approach them. At the touch of a button, the gas detector will check for the presence of multiple gases and provide a reading.

The Marine 5™ can detect up to five gases with its catalytic and toxic sensors, infrared capabilities and photo ionisation detectors. Most portable detectors will be calibrated to test for some or all of the standard four gases (Flam, H2, CO, and O2).

Some portable gas detectors are affected by sensor poisoning and/or drift. Others may not be compatible with Zone 0 (flammable) or inert (oxygen-free) environments.
We can safely say the Triple C is the toughest portable gas detector on the planet, as its IP68 rating attests. The Triple C can withstand Zone 0 and inert environments with no impact on performance; it is immune to fine dust and can be submerged up to 1.5m underwater too.

It doesn’t need calibrating, is entirely customisable, can be digitally assigned to a crew member or department, and is the only portable gas detector with three years of battery life, allowing for 90 seconds of alarm each day.
We understand that one of the cumbersome tasks onboard is trying to ensure all of your equipment is fully functional with no batteries or charges being run down, so this is borne in mind with the design of all of our products.

Why Choose Our Mobile Gas Detectors?

A SOLAS requirement (SOLAS Chapter XI-1/7) is that “Every ship to which Chapter 1 applies shall carry an appropriate portable atmosphere testing instrument or instruments….” There are so many confined spaces or void spaces in which gas can accumulate that they need to be checked and verified as safe before entry.

Our comprehensive range of marine gas detection ensures the safety of all crew members at all times whilst keeping up to date with IMO regulations.

The detectors possess a range of impressive benefits;

Battery Life – up to 3 years with no battery replacement.
Bump testing – some models, such as the Triple C, do not require bump testing.
Impressive calibration accuracy.
Hassle-free data logging.
Maintenance Updates.

The approach to ship safety, performance and crew welfare is why Martek Marine consulted as an industry authority to help reduce the number of unnecessary deaths when IMO Regulation XI-1/7 was drafted.

Portable/Mobile Gas Detection FAQ's

What is Portable Gas Detection?

Gas detectors use a sensor to measure the concentration of certain gases in the atmosphere. The sensor serves as a reference point and scale, producing a measurable electric current when a chemical reaction caused by a specific gas occurs. The sensor will monitor these currents and alarm the user when the presence of gas approaches a hazardous amount.

At Martek Marine, we offer various options in portable gas detection options, from single gas detection to a world-first in gas detection.

How do portable gas detectors work?

The portable gas detectors work by monitoring different gas levels in the air. These devices are generally battery operated and used for safety. Once they detect a higher than normal concentration of gas in the air, they warn people in the location through a series of really hard to miss audible beeps.

What gases do the monitors detect?

Using a 4 gas monitor can protect your workers in any environment by assessing the four main gases Oxygen (O2), Carbon Monoxide (CO), Hydrogen Sulfide (H2S), Methane (CH4), or other combustible gases you’re checking for.

What is the difference between portable gas detectors and fixed gas detection?

Unlike fixed gas detectors which permanently monitor a designated area, portable gas detectors are mobile devices used by personnel to provide pre-entry gas level checks. This means they can test the area before entering it to assess the levels of gas in the air to ensure it is safe for human entry.

Personal or Portable Detectors – what’s the difference?

The size, capability, and usage can vary greatly between personal gas detectors and portable gas detectors.

However, these distinctions might not always be clearly defined by suppliers which can leave you feeling confused.

Which type and model of detector you choose will depend on your own particular requirements:

the gas or gases you need to monitor
the frequency and conditions of usage
and the level of detail you need in your reporting.

PERSONAL DETECTORS

As the name suggests, personal gas detectors are small enough to be clipped to the belt or clothing of the user.

Because they’re designed to be worn, they need to be able to withstand the kinds of knocks or damage that come when they’re carried into confined spaces, so you’ll usually find that they have a high IP rating.

To keep everything compact, they’ll probably use a self-contained battery which is sealed inside the detector. When the battery reaches the end of its life, the device itself will need to be replaced.

Personal gas detectors are usually much cheaper than portable detectors but their capabilities and screen displays may be more limited and they don’t always allow for calibration or pump options.

They’re often used for detecting one particular gas – like our hydrogen sulphide and oxygen single gas detectors – but more advanced devices can detect four or even five.

PORTABLE DETECTORS

These larger and more complex devices can offer a more sophisticated solution both in the number of gases they’re able to trace and their data logging.

Although they’re not as durable or easy to carry as personal gas detectors, they do come equipped with a pump which enables you to test remotely.

They’re also easier to calibrate and you can re-charge or change their batteries without the need to replace the whole unit.

The greater number of sensors on a portable detector means that they can provide a wide variety of different feedback as well as storing much more information.

The software on the Marine Tankscape, for example, provides complete data logging of gas readings with tank identification and vessel location which makes detection, analysis, and action planning easy.

It also enables you to print tamper-proof calibration certificates on-board, further reducing costs and making the process far less complicated.
