Gas Sensor Calibration - GasLab.com

To perform a span calibration, a gas sensor is exposed to 2 gases, one with no target gas, and one with a known amount of the target gas. Span calibration begins by the sensor being exposed to a pure inert gas like nitrogen or argon. In the case of oxygen sensor calibration, because the gas contains no oxygen, the sensor’s reading for 0% oxygen is recorded in the sensor’s EPROM memory.Get price
