Description

The RPH 050 bench allows the study of pH regulation. A centrifugal pump and a dosing pump provides basic and acid solution in the test reactor. A pH sensor measures continuously the value of pH in the reactor. In the reactor, a centrifugal pump is connected to additional the acid or the soda to create a disturbance. A digital PID controller receives pH information and must adjust the opening of the metering pump to achieve the setpoint. The homogenization of the solution is realized thanks to agitator with variable speed. The unit comes complete with instrumentation, technical and educational materials in english and all the accessories required for proper operation (Included the supervision software).The robust design of this equipment makes it perfectly suited for school use.

Its anodized aluminum structure gives it great strength as well as great flexibility of integration into your premises. The manufacture of this equipment meets the European machine directive
