Calibration is a crucial process in ensuring the accuracy and reliability of gas measurement instruments. Gas calibration involves comparing the readings of the instrument to known gas concentrations from reference stations or devices. By adjusting the calibration parameters, the instrument can provide precise measurements, maintaining the integrity of gas monitoring systems.
The Sensorbee Cloud Portal offers a comprehensive calibration method that combines both baseline and span calibration:
Baseline and Span Calibration: This calibration procedure involves identifying two specific periods: one where the sensor is exposed to a minimum reference gas concentration (preferably zero concentration of the targeted gas), and another where the gas concentration reaches a maximum reference value or a significantly high value. By adjusting the calibration parameters based on these two conditions, the sensor's response to the absence of the target gas and its sensitivity across the entire measurement range can be optimized.
Note: The calibration feature is only available for accounts with the Sensorbee Cloud Analytics Package.
To perform calibration using the Sensorbee Cloud Portal, follow these steps:
  1. Baseline and Span Calibration: Follow the instructions to identify the appropriate time periods for minimum and maximum reference gas concentrations and adjust the calibration parameters accordingly.
  1. R² Correlation: Assess the correlation between the sensor's measurements and the reference data to evaluate the effectiveness of the calibration process.
  1. Upload Reference Data: Provide the necessary reference data to facilitate accurate calibration of the gas sensors.
By following this comprehensive calibration procedure, you can ensure that your gas measurement instruments provide accurate and reliable data, enabling effective gas monitoring and analysis.
