Selecting an Oxygen Calibration Gas
A 20.9% oxygen calibration gas is used to simulate normal atmospheric conditions and verify baseline sensor accuracy. When selecting your calibration gas, ensure it aligns with your calibration procedure, especially if used alongside zero gas and span gases for complete system validation.
Why Oxygen Calibration is Important
Oxygen levels outside the normal range can create dangerous conditions. Low oxygen levels can lead to asphyxiation, while elevated levels increase fire risk. Calibration gas ensures detection systems accurately measure oxygen concentration and respond appropriately to unsafe conditions.
Understanding Oxygen Calibration
Oxygen sensors are typically calibrated using a known reference concentration such as 20.9%, which represents normal atmospheric conditions. This ensures accurate baseline readings and proper alarm functionality in safety systems.
