A pH electrode that has become slow to settle, drifts, or will no longer calibrate within specification is usually not worn out — its glass membrane and liquid junction are coated. The correct cleaning reagent will often bring it back rather than requiring a new electrode.\u003c\/p\u003e\n\n\u003cp\u003eThe key is matching the reagent to the fouling. Different deposits need different chemistry, and using the wrong one wastes time and can leave the coating in place. Choose based on what your samples contain.\u003c\/p\u003e\n\n\u003ch3\u003eWhich cleaner do I need\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e220\u003c\/strong\u003e (part no. 3014028653) — breaks down \u003cstrong\u003eorganic\u003c\/strong\u003e deposits.
