Claim Text:
1. A method of adjustably inserting an electrochemical potential measurement sensor into a process fluid, the method comprising: (a) providing an insertion assembly, the insertion assembly comprising: (b) extending the open distal end portion of the receptacle through a wall of a process fluid vessel; (c) placing the electrochemical sensor into the elongated electrode holder; (d) slidably placing the electrode holder into the receptacle, wherein the electrode holder is configured for slidable movement within a range of motion extending from an inserted position in which the aperture of the electrode holder is open to process fluid within the vessel, to a retracted position in which the aperture of the electrode holder is closed to the process fluid; (e) sliding the electrode holder into a fluid insertion position at any of a plurality of locations within its range of motion; (f) clamping, with the leverage member, the electrode holder in the fluid insertion position; (g) operating the electrochemical sensor to detect an analyte associated with the process fluid; (h) releasing, with the leverage member, the electrode holder; (i) sliding the electrode holder into the retracted position to engage the distal end of the receptacle with the flange, prevent further proximal movement of the electrode holder relative to the receptacle and close the aperture to the process fluid; (j) clamping, with the leverage member, the electrode holder in the retracted position; (k) removing and replacing the electrochemical sensor after said (j); and (l) repeating said (e)-(g).
