Product Description

Wide Range Oxygen Dioxide Sensor High Quality O2 Sensor

DESCRIPTION
When voltage is applied to a zirconia electrolyte cell, oxygen is pumped through the zirconia disc from the cathode side to the anode side because the carriers of the current flowing through the zirconia electrolyte are oxygen ions. By attaching a cap with a pinhole on the cathode side of the cell and by increasing the voltage over the cell the current shows saturation due to the rate limiting step in the transfer of oxygen to the cathode. This saturation current is called limiting current and is nearly proportional to the ambient oxygenconcentration.
Below the advantages of the oxygen sensor:

measuring range *0 ppm to *6% oxygen
 High accuracy
For many types a more or less linear characteristic

Small temperature dependence of the sensor signal
Low interference with other gases
Long service life

In many cases  Single point calibration necessary only once
