Features PPM or LEL hydrocarbon detection at the push of a button, infrared sensors for CO2, methane or hydrocarbons in LEL and % volume ranges, PID sensor for detecting high and low ppm levels (0-50 & 0-2,000) of VOC gases, methane elimination feature for environmental applications, and a list of super toxic gases and measurable ranges. Some wear out relatively quickly, while others could conceivably last forever. 0000014808 00000 n It is heavier than air and will be found in low lying areas, but remember, when you heat it up in a fire, it will rise and move throughout the structure. 0000013342 00000 n CO is flammable at 12.5 percent, equal to 125,000 ppm. XA-4400II Portable Gas Detectors > Multi Gas Detectors. As discussed in my last article, firefighters noticed a decrease in O2 value on their meter that was later determined to be displaced by a liquid CO2 leak. 3. So, if a gas is flammable at four percent, then it is equal to 40,000 ppm, but when we look at O2, the numbers do change a bit. 0000023690 00000 n 0000001713 00000 n The multi-gas analyzer consists of a portable bellows pump and detector tubes. Here is a very quick overview to help you understand basic gas sensor technology. Understanding your readings, how to reset alarms, finding peak values, and cross sensitivities issues are all extremely important to ensure safe operations. By choosing “I Agree”, you understand and agree to Clarion’s Privacy Policy. The meter uses a 10.6-electron volt lamp, which is the amount of energy required to remove an electron from the atom or molecule. A portable gas detector is very important for the safety of workers and it is equally important to ensure that this equipment is correctly calibrated and regularly tested for accuracy. It is looking for toxic chemicals and reads in ppm. trailer Portable detectors are supplied as either diffusion detectors measuring the ambient air for gas and vapours, or with a gas sample pump. They are produced by many different manufacturers, but they all have the same basic operations. Monitor gas in confined spaces with GasAlertMax XT II. combustion of a hydrocarbon flame (oxidation reaction) mainly produces water (H2O) and carbon dioxide 0000001895 00000 n Multi-Gas Detector. This type of equipment is used to detect a gas leak or other emissions and can interface with a control system so a process can be automatically shut down. Each of these chemicals is potentially dangerous to civilians and first responders and should not be taken lightly. 0000024283 00000 n If you purchase gas detectors, you’re responsible for ensuring that the instruments are working properly and will alert workers to potential hazards. Some meters will include a fifth sensor, which monitors the ionization potential (IP) or sulfur dioxide (SO2). (Photo by author.).

Remember, you might be in a safe environment with low LELs or no readings, but the source of the leak could be at the LEL, and the explosion or ignition could still harm you.

����e�Yq��(. Most meters are calibrated using pentane as the baseline gas for LEL. Blackline’s G7 connected gas detection system delivers an exclusive customizable, modular design, providing tailored comprehensive gas detection for every work scenario. As explained in my last article, CO is a flammable gas that is poisonous (toxic), colorless, odorless, tasteless, and slightly lighter than air at room temperature. There is a relationship between ppm and percentage; normally, 10,000 ppm is equal to one percent. 0000011472 00000 n
Within this broad categorization, they are further defined by the technology they use: catalytic and infrared sensors detect combustible gases and electrochemical and metal oxide semiconductor technologies generally detect toxic gases. 0000080101 00000 n
So, when you are using a hoseline to put a fire out, you will be cooling the area; the CO will then get heavier and sink to low-lying areas. These gases include CO, H2S, SO2 and the IP that we monitor with our meter. Toxic gases are monitored in parts per million (ppm) because of the very low values that are dangerous to us. Multi-Gas Detector, Detects Oxygen, Carbon Monoxide, Volatile Organic Compound, Sensor Range O2 0 to 30.0 Percent, CO 0 to 500 ppm, VOC 0 - 2000 ppm, Housing Colour Black, PID Ionization Energy Level 10.6 eV, Operating Temp. There is a lot you need to know if you put any type of metering device in your hands.
