It is the most commonly used multi gas detector in the industry (sanitation, public works, steel, confined space entry, etc.). It simultaneously detects explosive combustible gas (natural gas, LPG, hydrocarbons, alcohols and solvents), hydrogen sulfide (H2S), carbon monoxide (CO) and lack of oxygen (O2).
What does a gas monitor 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.Nov 24, 2020
What do 4 gas monitors detect?
The 4 gas monitor typically detects carbon monoxide (CO), oxygen (O2), hydrogen sulfide (H2S) and combustibles (EX).Jun 25, 2021
How does a multi gas meter work?
In catalytic combusion sensors, a heated wire is used to detect flammable gases. Power is applied to a special wire coil, as with a traditional light bulb. The wire filament is selected and specially treated so that the hot surface will react and will readily burn (oxidize) gases that come in contact with it.
What 4 gases does a 4 gas monitor detect?
Find an ideal 4 gas monitor to protect workers in various environments and detect gases like oxygen (O2 Monitor), hydrogen sulfide (H2S Monitor), carbon monoxide (CO Monitor), and lower explosive levels of a variety of combustible gases.
What is a 4 gas detector?
A 4-gas detector is a gas monitor that is intended to detect combustible gas. ... It is used most commonly as a personal gas monitor in industries such as sanitation, public works, steel, or other confined space work. They are also known as LEL (lower explosive limit) gas detectors.Mar 29, 2021
What gases do gas detectors detect?
Several types of gas sensors exist, and each has distinctive characteristics. Most devices can measure and detect ammonia, carbon dioxide, nitrogen dioxide, bromine, arsine, ozone, and other gases. Some models are fixed, while others are portable and can be easily moved from one location to another.Aug 19, 2019
How do I test my MSA gas detector bump?

How do you bump test a gas monitor?
To do this, put the gas detector into bump test mode, then apply the gas. The gas detector will either cycle through each individual sensor or do them all at once, depending on the gas detector's settings. After the test is complete, the monitor will display results, showing whether it passed or failed the bump test.Nov 17, 2020
How do you bump test MSA 4xr?
- Attach the tubing on to the regulator.
- Screw the regulator to the calibration gas bottle and ensure the valve is closed for now.
- Attach the calibration cap to the front of the monitor.
- To activate the bump test mode, press the DOWN arrow.
