¹Sensor and interface for correct barometric pressure compensation.
²Prolonged operation below 0.1% O₂ can damage the sensing element.
³Range selectable by altering the position of the jumper links on the PCB, refer to datasheet for details.
⁴Assuming barometric pressure (BP) remains constant.
⁵As the O₂ sensor measures the partial pressure of oxygen (PPO₂) within the measurement of gas deviation in the BP from the present during calibration will cause readout errors proportional to the change, e.g. if the sensor reads 21% O₂ at 1013.25mbar and the BP increases by 1%, the sensor readout will also increase by 1% to 21.21% O₂.
