CO2 Sensor Calibration: What You Need to Know |

Most of our CO2 products use nondispersive infrared (NDIR) carbon dioxide sensors. These rely on an infrared light source and detector to measure the number of CO2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO2 molecule counts.

CO2 Sensor Calibration: What You Need to Know |

All carbon dioxide sensors need calibration. Depending on the application, this can be accomplished by calibrating the sensor to a known gas or using the automatic baseline calibration (ABC) method. Both have pros and cons you should know. Most of our CO2 products use nondispersive infrared (NDIR) carbon dioxide sensors.

Bad Oxygen Sensor: Symptoms Replacement Cost AutoZone

Signs of a Faulty or Failing Oxygen Sensor. An oxygen sensor does not have to fail completely to give you problems. On the contrary, even a failing O2 sensor (sometimes called a “lazy” O2 sensor) may cause your car to have a few issues. If you notice any of the following signs, you may have a bad O2 sensor or one that is about to go bad: An illuminated checkengine light; A rough engine ...

20160112· This sensor can fail gradually, or all at once. In most cases, the Check Engine Light is illuminated if a TPS failure is detected. Also, most manufacturers provide a “limp home” mode of operation with reduced power if a failure is detected. This is intended to at least allow a driver to get off a busy highway in a safer manner. Once the TPS begins to fail, even partially, you’ll need to ...

20170216· Most cars default to the factory airtofuel ratio if the oxygen sensor fails, which can cause problems because of nonstandard temperature, moisture, or air composition. If your oxygen sensor is failing, then its readings will be inaccurate, again, resulting in a suboptimal fueltoair composition.
