Multi-gas detector are protect workers in a variety of environments, including enclosed spaces like manholes, sewers, and other areas with poor ventilation. They detect gases like oxygen (O2 Monitor), hydrogen sulfide (H2S Monitor), carbon monoxide (CO Monitor), and lower explosive levels (LEL Monitor) of a variety of combustible gases. We offer a range of monitors for you to choose from. View our gas monitor choices below. You can also get a reliable single-gas H2S monitor, O2 monitor, CO monitor.

Carbon Monoxide:
CO is an odorless, colorless gas that can be fatal in large quantities. It is most often found in the exhaust fumes of combustion vehicles, including cars, trucks, and other industrial equipment. It can also come from stoves, grills, generators, and furnaces. Prolonged exposure or exposure to large quantities can result in a variety of symptoms, including dizziness, fatigue, nausea, vomiting, and chest pain. In severe cases, it can lead to fainting and even death.

Hydrogen Sulfide:
H2S is a colorless gas that often smells like rotten eggs, which is why it’s often referred to as sewer gas. Though your sense of smell is extremely unreliable as an indicator of concentration. It is common in the wastewater, natural gas, and oil refining industries. It is heavier than air, which causes it to sink to low-lying areas. Exposure to H2S can lead to nausea, headaches, confusion, fainting, and even death.

Oxygen:
Most 4-gas monitors will also monitor the level of oxygen in the atmosphere. Every worker needs access to oxygen to breathe. Monitoring oxygen levels can help prevent injury and death on the job. The Occupational Safety and Health Administration (OSHA) mandates that all oxygen gas detection instruments trigger an alarm when oxygen level drops below 19.5% volume.
