Title:
ORP SENSOR FOR STRONG ELECTROLYTE AND METHOD FOR MEASURING ORP OF STRONG ELECTROLYTE
Document Type and Number:
Japanese Patent JP3539459
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To shorten the rising time of an ORP sensor for sensing a strong electrolyte being delivered from the electrolyte bath.
SOLUTION: At the time of back wash where the electrolyte is not delivered or immediately after driving an apparatus, a reference electrode 3 comprising the Ag/AgCl electrode of an ORP sensor is applied with a negative potential from a power supply 6 for feeding a positive potential to an indication electrode 4 comprising a Pt electrode. After applying a voltage for a predetermined time, a switched 5 is turned on to begin the measurement. Consequently, a DC voltage is applied to activate the surface of both electrodes thus enhancing the affinity to strong electrolyte. This constitution shorten the rising time and the true ORP value of electrolyte can be measured quickly.
