Carbon dioxide tracer is a professional equipment used for precise positioning and tracking of the flow path of carbon dioxide (CO ₂), widely used in fields such as environmental monitoring, geological exploration, agricultural production, and industrial emission control. Its core principle is based on infrared sensing or laser spectroscopy technology, which can detect real-time changes in CO ₂ concentration in the environment and generate dynamic distribution maps. The following are the key usage details and operating points of the device:

1、 Preliminary preparation and equipment inspection

1. Environmental adaptability assessment

-Select the appropriate model based on the application scenario (portable handheld devices are suitable for field operations, while fixed multi probe systems are suitable for long-term monitoring).

-Ensure that the working temperature is within the equipment calibration range (usually 0-40 ℃), and avoid special humidity or corrosive gas environments.

-Check the power level or stability of the external power supply, and reserve sufficient battery life to complete continuous observation.

2. Initial calibration and zeroing

-After starting up, it is necessary to perform "baseline calibration" in clean air to eliminate environmental background interference.

-If the device supports multi-point calibration function, a standard gas of known concentration should be input for calibration to improve measurement accuracy.

-Verify whether the sensor response time meets the requirements (usually<30 seconds) to ensure real-time data.

2、 On site operation standards

1. Deployment strategy and sampling frequency

-Reasonably arrange monitoring points according to the size of the target area, focusing on potential leakage sources (such as pipeline interfaces, tank breathing valves) or diffusion channels (chimneys, ventilation openings).

-Set appropriate sampling intervals (it is recommended to collect high-frequency data initially and extend them appropriately after stabilization) to capture transient leakage events.

-Adjust the probe height and angle based on factors such as wind direction and terrain to optimize signal capture efficiency.

2. Dynamic tracking and visualization analysis

-After starting the continuous monitoring mode, observe the evolution trend of CO ₂ concentration cloud map through the supporting software and identify high concentration abnormal areas.

-Use the vector arrow overlay function to visually display the direction and rate of gas diffusion, assisting in determining the leakage path.

-Conduct targeted retesting of suspected leakage points and compare historical data to confirm whether they are sustained emissions.

3、 Data recording and interference elimination

1. Effective data screening criteria

-Exclude sudden changes caused by device shaking and electromagnetic interference, and retain stable data for analysis.

-Annotate key time nodes (such as equipment start stop and sudden weather changes) for subsequent correlation analysis.

-Synchronize and save environmental parameters (temperature, humidity, atmospheric pressure) when exporting raw data for cross validation purposes.

2. Common interference response plans

-Moisture impact: Enable the built-in dehumidification module of the device or install a waterproof filtration membrane to prevent condensation from adhering.

-Dust obstruction: Regularly clean the probe lens and use a blowing device if necessary to keep the optical path unobstructed.

-Cross sensitivity to other gases: For environments containing composite gases such as methane and ethanol, select filter versions with stronger specificity.

4、 Post maintenance and quality control management

1. Daily maintenance process

-Clean the surface dust and oil stains of the probe after each use and store it in a dry and shock-absorbing box.

-Perform a zero drift check once a month and recalibrate if necessary to maintain measurement accuracy.

-Replace aging sealing rings and vulnerable components every quarter to extend the service life of the equipment.

2. Performance verification mechanism

-Carry standard gas cylinders to the site for surprise calibration to verify measurement deviations under actual working conditions.

-Participate in third-party comparative testing, obtain institutional certification reports, and ensure the legal validity of data.

-Establish equipment log files, record maintenance history and calibration records in detail, and achieve full lifecycle traceability.

5、 Safety precautions

-Before entering a confined space, it is necessary to check the oxygen content to prevent the risk of suffocation caused by the accumulation of CO ₂ in an oxygen deficient environment.

-Wear personal protective equipment (mask, goggles) to avoid direct contact with high concentrations of CO ₂ that may cause discomfort.

-It is strictly prohibited to use non explosion proof equipment in flammable and explosive places to prevent accidents caused by electric sparks.
