What does MSA Altair 5x detect?
What does MSA Altair 5x detect?
Detects combustible gases in LEL and/or volume percentage range, oxygen, carbon monoxide, carbon dioxide, hydrogen sulfide, sulfur dioxide, ammonia, chlorine, VOCs, and many others depending upon sensor configuration.
What does a 5 gas monitor detect?
GasAlertMicro 5 IR portable gas detector simultaneously monitors up to five atmospheric hazards including carbon dioxide (CO2), oxygen (O2), combustible gas (%LEL), and a wide selection of toxic gases.
How do you use the Altair pump probe?
(1) Rotate the coiled tubing connector counter-clockwise and pull. (2) Firmly insert the device into the ALTAIR Pump Probe 4/4X charging cradle. (3) The Charge LED is used to indicate the charge status.
What does LEL mean in gas?
Lower explosive limit
The term L.E.L. stands for Lower explosive limit of a combustible gas or vapor. It’s the lowest level a gas can ignite in air in the presence of an ignition source. Conversely, U.E.L (upper explosive limit) is the maximum level in air that a gas may ignite.
What is comb gas?
COMBEX – Combustible/Explosive (%) (100% =LEL) O2 – Oxygen (%) CO – Carbon Monoxide (PPM)
What are the 5 typical sensors found on a 5 gas meter?
In their standard configuration, these meters have sensors for oxygen depletion, combustible gases (lower explosive limit or LEL), carbon monoxide (CO), and hydrogen sulfide (H2S).
What four gases does the multi warn detector monitor?
Multi Gas Detection Typically a four-gas detector will be able to detect Oxygen (O2), Hydrogen Sulphide (H2S), Carbon Monoxide (CO). They will also detect the general LEL (Lowest Explosive Limit) for present combustive gases.
How often should you calibrate a MSA Altair 5x?
For users who do not wish to develop their own frequency, we recommend they calibrate once a month. For those who “bump test” their instrument prior to each use, the calibration cycle can be extended to three to six months for instruments that successfully pass the bump gas test.
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 UEL in fire?
Upper explosive limit (UEL): the highest concentration of gas or vapour which will burn or explode if ignited. From the LEL to the UEL, the mixture is explosive. Below the LEL, the mixture is too lean to burn. Above the UEL, the mixture is too rich to burn.
Why is methane used for LEL?
If poisons (silicone, airborne lead) or inhibitors (Sulphur or chlorinated compounds) are present in the atmosphere then LEL sensor sensitivity will be affected. In these situations, methane can be the best choice for calibration as it will provide the faster indication of sensor degradation.
What is the difference between a 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.
When should I bump my gas monitor?
A bump test, also known as a functional test, should be performed at the start of each day’s use. This procedure tests the alarms and sensors of a gas detector to be sure they are functional. The test exposes the detector to a known concentration of gases that exceed the lowest alarm set-point for each sensor.
How often should a gas detector be calibrated?
every six months
If a gas detector has been subject to high gas concentrations or unusual conditions, it is generally recommended that a bump test or calibration be performed. At a1-cbiss, we recommend that gas detection equipment is calibrated at least every six months for a reliable performance.
What is LEL level?
The term L.E.L. stands for Lower explosive limit of a combustible gas or vapor. It’s the lowest level a gas can ignite in air in the presence of an ignition source. Conversely, U.E.L (upper explosive limit) is the maximum level in air that a gas may ignite.
