The gaseous oxygen sensor has been designed to read O2 levels from 0 – 420 ppt. The sensor comes calibrated and ready to use right out of the box.

The Atlas Scientific EZO-O2™ Embedded Oxygen Sensor is an electrochemical sensing device that detects the partial pressure of oxygen through reduction. The sensor can be thought of as a small fuel cell. When the oxygen comes in contact with the sensor, the “fuel cell” begins to produce a current. A teflon membrane ensures that the oxygen enters the sensor at a steady rate.
