Electrode module for titration apparatus

DETAILED DESCRIPTION Briefly and in general terms, the present invention resides in a new and improved electrode module for titration apparatus which overcomes the disadvantages of the prior electrode arrangements.
The electrode module is simple, rugged, and inexpensive in construction, is easily maintained and cleaned, and is arranged to enhance electrode performance and minimize electrical and chemical interference between electrodes.
To this end, in accordance with a primary aspect of the invention, the electrodes with a long useful life but which require frequent cleaning (the amperometric anode, amperometric cathode, and the coulometric cathode) are combined into a single electrode module, and the electrode module is mounted independently from the remaining electrode (coulometric anode).
The relative lengths and orientation of the electrodes within the module are selected to maximize electrode performance.
The module is mounted in a manner enabling easy removal for cleaning and is ruggedly constructed to minimize damage during operation or cleaning.
Other advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawings.
