Question
What concentration of HF can the HF resistant pH sensor handle?
Summary
pH sensors and HF concentrations accepted
Answer
The sensor is fairly accurate up to pH 2. If all of the acid is in the form of HF, that would imply 0.01 Molar acid. The probe would be ok with transient conditions to 0.1 Molar, although accuracy probably wouldn’t be very good.
