Page 22: Maintenance On Operation
< 3. Maintenance on operation > Maintenance on operation Operation and Periodic Maintenance 3.1.1 Calibrating ORP Sensor Using Checking Solutions Dirt attached to the liquid junction or sensitive parts (platinum electrodes) may have an adverse effect on electromotive force and response characteristics, so ORP sensors require periodic cleaning for good operating conditions. - Page 23 < 3. Maintenance on operation > The time required for maintaining the saturated concentration of a KCl solution in a sensor is greatly influenced by the sensor's operating conditions. For example, as temperature variations in measured solutions are great, or as solution temperatures are high, so too does the amount of KCl solution drained from the liquid junction increase, thereby shortening the period of time for maintaining the saturated concentration.

In doing this, do not leave any air pockets in the body. (8) Restore the liquid junction removed in Step (3) above to its original position. -
