Abstract: An aspect provides a low slope electrode device, including: a low slope measuring electrode for placement in an external sample solution, said low slope measuring electrode comprising: an electrode disposed within a glass container including an internal buffer solution and at least partially enclosing the electrode of the low slope measuring electrode, the glass container having two pH sensitive regions; an external buffer container including an external buffer solution and at least partially enclosing one of the two pH sensitive regions; and a separating element that separates the two pH sensitive regions; wherein: a first pH sensitive region of the glass container permits charge flow between the internal buffer solution and the external sample solution; a second pH sensitive region of the glass container permits charge flow between the internal buffer solution and the external buffer solution; the separating element, the first pH sensitive region, and the second pH sensitive region establish a charge flow circuit through the internal buffer solution, the external buffer solution, and the external sample solution; and the charge flow circuit acts as a voltage divider for the low slope measuring electrode. Other aspects are described and claimed.
