Signet's own calibration guidance names pH glass electrode failure causes as coating, elevated temperature, and glass erosion "by abrasion, and strong sodium hydroxide (NaOH), potassium hydroxide (KOH) or hydrofluoric acid (HF) solutions"; a used electrode reading more than ±0.84 pH off theoretical value should be replaced.
Drinking water pH/ORP monitoring looks low-stakes until the electrode fails silently from reference-junction fouling. ProMinent's PHES pairs a lead-free ceramic diaphragm rated to 60°C/3 bar for exactly this duty, while GF Signet's 2774-2777 double-junction design exists specifically to resist the trace copper, lead, and mercury contamination municipal source water can carry.
