Ammonia gas sensing electrode measuring cell device

The utility model discloses an ammonia gas sensing electrode measuring cell device, which comprises a stirring motor, an ammonia gas sensing electrode and a measuring cell, and is characterized in that the stirring motor is arranged just below the measuring cell, wherein the upper part of the stirring motor is provided with a magnet; the bottom of the measuring cell is provided with a rotatable stirrer; and the ammonia gas sensing electrode is slantwise inserted into the measuring cell and is fixedly arranged on an ammonia gas sensing electrode fixing clip at the upper edge of the measuring cell according to a preset angle which is 60 degrees with the horizontal plane. According to the ammonia gas sensing electrode measuring cell device, the measuring volume is reduced, the sensitivity is improved, and the attachment of bubbles to an electrode membrane is reduced through a proper ammonia gas sensing electrode mounting angle, so that the measuring error is reduced. Meanwhile, by providing a constant stirring motor rotation speed, solution can be quickly and uniformly stirred so as to improve the response time.
