Use the 4 gas monitor to monitor the four main gases oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), methane (CH4) or other combustible gases. Use the 4 Gas Monitor to protect your workers in any environment.

Portable gas detectors can detect any four gases and display them all at once. The screen will display the level of each gas and provide audible and visual alerts in the presence of flammable or toxic gases - giving you an immediate idea of the safe level of air in the area.

Why Should I Use A 4 gas monitor ?

Natural gas is dangerous on many levels, one of which is that it is a silent killer. If your job involves gas, you need to know that your crew is safe at all times, especially when working in confined Spaces.

There are two main ways to assess gas levels:

Stationary gas detector


Given that this guide deals with portable gas detectors, we will only cover this briefly, but you will need to check the legal requirements for your type of vessel to determine if your regulations stipulate that permanent gas detection systems should also be installed.

These are fixed gas detection systems to assess gas risk at any time. You can customize the 4 gas monitor to your needs, where the sensor can be placed wherever you need it. Gas levels are then transmitted to controllers throughout the day.

Not all ships are required to install a fixed gas detection system. But cargo pump rooms or coolers use 4 gas monitors to protect them from harmful gas buildup.

Portable gas detector

Another option is to use portable gas monitors, worn by staff, used to test an area immediately before entering it.

Different gases occupy confined Spaces in different ways. If there's no oxygen in the space it can quickly cause you to lose consciousness.

Testing a confined space before entering it will detect the level of gas present and issue or display an alarm as a warning. No matter what kind of portable gas detector you use, they highlight the presence of gas and enable the crew to safely enter a confined space.
