Icon's P14 family is split at a quantified 4000ppm HF concentration breakpoint — below that, the P14H sensor is rated; above it, the process needs the P14F.
Hydrofluoric acid service is one of the few chemistries where a pH sensor's failure mode is quantified rather than a vague "harsh chemical" warning — Icon's P14H/P14F split at a real 4000ppm HF threshold, and GF Signet's 2774-2777 double-junction design exists to block copper, lead, and mercury poisoning in general chemical-processing streams. James Riggins specs the electrode to the actual concentration in the process, not just "pH sensor for chemicals."
