Stepper motor peristaltic pump used in ammonia nitrogen detector

The Ammonia nitrogen detector is used to determine the content of ammonia and ammonium salts in water, and can also be used to determine nitrate-nitrogen, total nitrogen, organic nitrogen, and other nitrogen-containing compounds.

The basic principle is: in an environment with a pH value greater than 11, ammonium ions are ionized to form ammonia, the solution is transferred through the ammonia gas-sensitive electrode membrane, the solution potential changes, and finally, it is converted to ammonia nitrogen concentration.

The stepper motor peristaltic pump is used to inject the test sample and reagent, the remaining liquid is also discharged by the stepper motor peristaltic pump.

Advantages of stepper motor peristaltic pump used in ammonia nitrogen detector:

Ø Convenient maintenance: the tube can be replaced, and it can be switched from one liquid to another in the shortest time, there is no need to disassemble and flush, just replace the stepper motor peristaltic pump tube.

Ø High precision: the scale function guarantees the filling accuracy of each injection, and the suction function prevents liquid backflow.

Ø No pollution: the fluid only contacts the pump tube.

Ø Good sealing: It has the good self-priming ability, can be idling to prevent backflow.

Ø Low shear force: suitable for conveying shear sensitive and corrosive fluids.
