Combined Polarising Circuit and Readout Meter

The Combined Polarising Circuit and Readout Meter is a battery operated unit that provides an analogue alternative to the Digital system for use with a single electrode.

The unit has two analogue meters which simultaneously display polarising voltage and oxygen levels. The controls allow adjustment of the polarising voltage, calibration of the electrode and enable the unit to be used without the oxygen meter reading (when being used with a chart recorder for instance). Two DIN sockets are located on the front panel for connection to the electrode and a chart recorder. A stirrer is not included.

Ordering Information

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