The Polarising Circuit is a simple, low cost, battery-operated unit that supplies the polarising voltage for a single electrode and produces an analogue output for a chart recorder.
The controls allow the polarising voltage (which is displayed on a meter) to be adjusted. The recorder output voltage is adjusted by a five position, coarse adjustment switch and a ten-turn fine potentiometer which enables the electrode to be calibrated to the recorder. The electrode and the recorder are connected via DIN sockets on the front panel. A stirrer is not included.
A comparison chart for our range of controllers is also available.

For a working oxygen measurement system you will need a controller and an electrode (the Polarising Circuit also requires a separate stirrer). Rank Brothers offers a range of Perspex oxygen electrodes and glass oxygen electrodes suitable for use with this controller.
