urea sensor can is a kind of parapodum urine burning organization sensor, by plant tissue (such as soybean meal) curing film, covered in ammonia or air oxidation of carbon gas sensitive electrode determination mechanism is soybean meal containing urea enzyme, can make the urea catalytic decomposition soon. Gas sensitive electrode can be measured ammonia and carbon dioxide emitted by the most, and calculate the urea content in J

Urea sensor including the connection of the fixed base metal chassis, metal chassis is equipped with chassis, chassis raised above sets the gasket on the chassis, the chassis on the sidewalls of the gasket is equipped with downwards grooves, chassis bump in the groove, the chassis raised within the hole wall in contact with the inside wall of groove, under the chassis bump with gaskets, valve installed in turn through the chassis gasket center hole, bumps on the hole in the center of the chassis, chassis gasket under the center hole, valve seat and the top of the urea sensor installation, even with fixed tube wall on the chassis of the gasket face contact with the lower end of the tube faces, chassis gaskets gasket under the hole inside the wall and chassis hole inside wall with valve installation of outside wall in contact. The present invention compact structure, high work efficiency. Use of this invention, is advantageous to the crystallization of urea in the urea solution, suitable for all kinds of urea sensor, especially urea sensor suitable for U.
