The pump supplies the cleaning solution to a nozzle which sprays the solution on the electrode.
Claims7
A cleaning apparatus for test electrodes disposed in a vessel containing a solution to be analyzed by the test electrodes in which the test electrodes are adapted to be sprayed by a jet of cleaning solution issuing from a nozzle in accordance with a predetermined program, the cleaning apparatus comprising:
- a pneumatically operating peristaltic pump means operatively connected with the nozzle for intermittently drawing the cleaning solution from a storage container and for ejecting the cleaning solution through the nozzle against the test electrodes so as to remove deposits of solids therefrom while the test electrodes remain in the solution.
