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 non-dispersive infrared (NDIR) carbon dioxide sensors.

Gas Sensor Calibration -

For example, if a CO2 sensor uses single point calibration when the “calibrate” button is pressed on the device in fresh air, the sensor’s software assumes the current stable reading is 400ppm CO2 and adjusts the curve with an offset value.

CO and LEL Sensor Testing-Carbon Monoxide Sensor Testing ...

Each CO Sensor or detection system covers a set distance. These gas detection systems use sensors to detect the buildup of carbon monoxide, a colourless and odourless gas, and activate fans and alarms when readings reach pre-programmed set points. Each sensor is specific and calibrated for detecting a certain compound. The sensors require annual testing and calibration to ensure proper ...

Also, make sure that the calibration gas that used to span adjust the CO sensor is not allowed to accumulate in the area where you fresh air adjust your instruments. Even though four or five ppm of CO is not harmful or dangerous, the presence of the gas can have an effect on the accuracy of the fresh air zero procedure. The most common interfering gas to have an effect on CO sensors is ...

Miniaturized or low volume (flat) CO sensors that contain less electrolyte, (and less dissolved oxygen) can become O 2 depleted more quickly. So, as a general rule, it is better when possible to use contaminant free fresh air to zero-adjust the sensor, and CO calibration gas that includes oxygen when a span calibration adjustment is performed.
