Which gases does a 4-way gas monitor detect?
To maintain workplace health and safety, it is essential to monitor air quality, especially in confined spaces where hazardous gases can accumulate undetected. These spaces, if left unchecked, can become potential death traps, as employees in industries like oil and gas may be exposed to toxic or oxygen-deficient environments without realizing it. A multi-gas detector, such as our 4-sensor gas detector, is designed to provide real-time warnings, allowing workers to evacuate or take precautionary measures before exposure becomes life-threatening. The 4-way gas monitor detects the four most common gas hazards:
- Carbon monoxide (CO)
- Hydrogen sulphide (H2S)
- Oxygen depletion (O2)
- Sulphur dioxide (SO2)
- Flammable gases
Gases are hazardous in multiple ways: they can be explosive, toxic, highly flammable and deadly. One of the most dangerous aspects of toxic gases is their invisibility—many of them are colourless and odourless, making them silent killers. That is why a 4-way gas monitor is indispensable in any environment where employees may encounter hazardous gases. In addition to 4-sensor gas detectors, we also provide single-gas detectors, such as an arsine gas detector, for industries that need specialized monitoring solutions.
