PASVE® DUAL is mounting and service valve for two pH sensors of diameter 12 mm. It can be used with practically all pH sensors in this size category.
PASVE® DUAL allows the cleaning and calibration of pH sensors without stopping the process. When required, this can be done automatically. To protect the sensor in abrasive processes, it can be turned to the measuring position only for the duration of the actual measurement. PASVE® DUAL is available in a manually operated type or equipped with a pneumatic or electric actuator.
