Apogee Oxygen Sensor Calibration

All Apogee oxygen sensors respond to absolute oxygen concentration in air, where common units of absolute gas concentration are partial pressure (e.g., kilopascals, kPa), mass per unit volume (e.g., grams per liter, g l-1), and number of molecules per unit volume (e.g., moles per liter, mol l-1). The absolute amount of oxygen in air is dependent on absolute (barometric) pressure and temperature, in addition to oxygen content of air. Therefore, Apogee oxygen sensors are not calibrated at the factory and must be calibrated by the user.

For information on calibrating your oxygen sensor or meter, please refer to the product manual >.
