WARNING
ISE detergent is a sodium hypochlorite solution. When handling bleach, wear protective
clothing, gloves, and safety glasses. It is harmful if swallowed and may cause eye or skin
irritation. In case of skin or eye contact, flush with large amounts of water.
5. Remove the cap (

detergent solution into the dummy electrode.
CAUTION
Be sure to tighten the cap on the dummy electrode. If the cap is loose or defective, the
ISE detergent solution may leak into the module and cause damage.
