Control Systems Unical 9000

The electro-pneumatic controller for fully automated pH measurement, cleaning, and calibration In combination with the Protos process analysis system and the SensoGate or Ceramat sensor lock-gates, Unical oers the ideal functionality of a complete system for automatic process control of a pH measurement. It allows highly accurate measurements to be taken, even with dicult process conditions such as high pressure, high temperatures, and high levels of impurities. The system can be installed next to the process, within the hazardous area.
