pH glass electrode
A hydrogen-ion responsive electrode usually consisting of a bulb, or other suitable form, of special glass attached to a stem of high @R05315@ glass complete with @I03106@ and @I03105@ system. Other geometrical forms may be appropriate for special applications, e.g. capillary electrode for measurement of blood @P04524@.
