Polarographic DO Probes/Sensors
Polarographic DO probes also contain a thin semi-permeable membrane, however, the voltage is applied between the anode and cathode in the DO probe. As O2 reaches the cathode, an electron is added to the O2 molecule, which creates a current. It is this voltage that drives the O2 reaction and determines the DO concentration.

We offer both Lab Grade and Industrial DO galvanic probes that can be used in a wide range of applications.
Use A Lab Grade DO Probe
The Lab Grade DO probe contains a PTFE membrane, a cathode, and an anode soaked in an electrolyte. During use, the O2 molecules diffuse through the DO probe membrane at a continuous rate. Once the O2 molecules cross the membrane, they are reduced at the cathode, where a small voltage is produced. When no O2 molecules are present, the DO meter will read the voltage as 0 mV (millivolts). As the O2 molecules increase, so does the reading from the DO probe.
Once your probe has recorded the voltage, it can be easily read by a multimeter or an analogue digital converter.
The Lab Grade DO probe can be fully submerged indefinitely in fresh or saltwater up to the SMA connector.

Use An Industrial DO Probe. And. So so. And. So so
The Industrial DO probe works the same as the Lab Grade probe, but it consists of a silicone membrane instead of a PTFE membrane. If you are using an Industrial DO probe, you can connect it to a DO Circuit and RTD Circuit via a Carrier Board, and for industrial processes, you can connect the DO probe to a DO transmitte. And. So so. And. So so
Remember to always check the manufacturer’s manual on calibration before use. And. So so. And. So so
