What gases does the MSA Altair 4X?
The ALTAIR 4X is an extremely durable Multigas Detector that simultaneously measures up to four gases from a wide range of XCell(R) sensor options including combustible gases, O₂, CO, H₂S, SO₂ and NO₂.
What does a MSA 4 gas monitor detect?
Item Details. MSA ALTAIR® 4X MSHA Multigas Detector is designed to detect the presence of Methane, Oxygen, Carbon Monoxide and Nitrogen. Detector with XCell® sensor technology offers durability and performance for mining applications.
How do you manually calibrate a MSA Altair 4X?
Up then while this is starting up it’s going to go through a checkpoint and it’ll show you all the different alarms it’ll start making sure the sensors are okay if you have an error.
How do you bump test MSA Altair 4X?
Press the dough needle the screen will show bonk test and you should select the medal button to proceed. Note on the valve to release the gas. The sensors should start to respond.
Which are the 4 main gases that we monitor using an altair4 4X?
What 4 gases does a 4 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.
Will a 4 gas monitor detect propane?
Acetone, industrial solvents, alcohol, ammonia, lacquer, thinners, benzene, methane, butane, naphtha, ethylene oxide, natural gas, gasoline, propane, halon, refrigerants, hydrogen sulfide, and toluene are just some of the combustibles that a 4 gas monitor can detect.
How do you calibrate a MSA Altair 4x gas monitor?

What is comb ex gas?
COMBEX – Combustible/Explosive (%) (100% =LEL) O2 – Oxygen (%) CO – Carbon Monoxide (PPM)
What is the difference between bump test and calibration?
The main difference between a bump test and calibration is that a bump test determines whether a DRPGM can detect if a possibly hazardous gas is present, while calibration checks that equipment is accurate.

What LEL is explosive?
The Lower Explosive Limit (LEL) varies from gas to gas, but for most flammable gases it is less than 5% by volume. This means that it takes a relatively low concentration of gas or vapour to produce a high risk of explosion.
Will a 4 gas monitor pick up natural gas?
What should the oxygen level be on a four gas meter?
Zero the instrument per the manufacturer’s instructions. The instrument should display readings of 20.9% O2, 0% LEL, 0ppm CO, and 0ppm H2S if properly zeroed. If not, re-zero the instrument in a known clean air environment.
Why is it called bump test?
The miners were betting their lives, and the lives of the rest of the miners, on the bright yellow birds. Each day the miners would show up for work and before heading underground for their shifts, they would grab a canary in its cage and lightly “bump” it against a wall to ensure the canary was still alive.
What is the purpose of a bump test?
A: A bump test is a functional test of a gas monitor. Sensors and alarm indicators are tested, ensuring acceptable performance of sensors and monitor before use. All sensors are challenged with a known quantity of gas, and instrument response is compared to the actual quantity of gas present.
What can a 4 gas monitor detect?
How do I calibrate my MSA gas detector?
What is the meaning of 1% LEL?
LEL, short for Lower Explosive Limit, is defined as the lowest concentration (by percentage) of a gas or vapor in air that is capable of producing a flash of fire in presence of an ignition source (arc, flame, heat).
What is 10% of the LEL?
LEL sensors measure percent of LEL. For example, Gasoline has an LEL of 1.4%. Therefore, 100% of LEL is 14,000 ppm of gasoline, 10% of LEL is 1,400 ppm of gasoline and 1% of LEL is 140 ppm of gasoline.
What is acceptable limit of oxygen?
A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone’s blood. If your home SpO2 reading is lower than 95%, call your health care provider.
What percent LEL is safe?
Atmospheres with a concentration of flammable vapors at or above 10 percent of the lower explosive limit (LEL) are considered hazardous when located in confined spaces. However, atmospheres with flammable vapors below 10 percent of the LEL are not necessarily safe.
