CO and CO2 – What’s the difference? |

The molecular weight of CO is , where the molecular weight of CO2 is This means that the CO2 gas is much more dense than CO. CO2 will collect near floor level while CO will collect closer to the ceiling. OSHA lists danger levels for CO beginning at 35 ppm, and for CO2 starting at a 5,000 ppm time-weighted average.

Understanding a Gas Sensor | Jaycon Systems

· Gas Sensor. Gas sensors serve to measure the concentration of gases in the environment. There are many different types depending on what you want to measure. In this case, the MQ-4 gas sensor can measure Liquefied Petroleum Gas (LPG), Methane (CH4), Hydrogen (H2), Carbon Monoxide (CO), alcohol, and smoke concentrations.

MQ-7 Semiconductor Sensor for Carbon Monoxide

Sensitive material of MQ-7 gas sensor is SnO 2, which with lower conductivity in clean air. It make detection by method of cycle high and low temperature, and detect CO when low temperature (heated by ). The sensor’s conductivity is more higher along with the gas concentration rising. When high temperature (heated by ), it cleans the other gases adsorbed under low temperature. Please ...

Bump Testing Gas Detectors Should Be Second Nature

· The first thing you should do before using your gas detector is to make sure it works. Without a bump test, how do you know that the gas detector you have can perform the way you need it to? Applying gas to the sensors in a detector is just like checking to see if your flashlight works. If the bump test fails, you know that troubleshooting or further maintenance is required.

Create Your Own CO Detector - Digi-Key

Building a CO (carbon monoxide) detector that can alert you to dangerous levels of CO can be done with as little as a gas sensor, an Arduino (or other microcontroller) and some resistors. Adding a few op-amps can boost the sensitivity to measure the amount of CO present in the environment. Expanding on this knowledge, you can build your own air quality monitoring station, and compare your own ...

Carbon monoxide detector - Wikipedia

The gas sensors in CO alarms have a limited and indeterminable life span, typically two to five years. The test button on a CO alarm only tests the battery and circuitry, not the sensor. CO alarms should be tested with an external source of calibrated test gas, as recommended by the latest version of NFPA 720. Alarms over five years old should be replaced but they should be checked on ...

The Gas Tracer has a version where the charcoal filter is removed from the CO sensor to allow for detection of H2S. The readout is displayed as ppm CO (not H2S), and there is no way to differentiate CO from H2S readings. GX-2012: Has the capability of H2S detection with a dedicated H2S sensor. With the Gas Tracer, H2S sensor is not available.

CO2 Sensor Calibration: What You Need to Know |

The most accurate method of CO2 sensor calibration is to expose it to a known gas (typically 100% nitrogen) in order to duplicate the conditions under which the sensor was originally calibrated at the factory. ISO certification is available on our high-end sensors to verify this process for medical, research or scientific purposes. Nitrogen calibration is also required if CO2 levels between 0 ...
