Patent number: 9316607Abstract: An adjustable insertion assembly for an electrochemical sensor includes an electrode holder to receive the sensor, having a distal aperture to permit process fluid to contact the sensor. A receptacle slidably receives the holder, for a sliding range of motion extending from fully inserted to fully retracted positions.
