Quality measuring instruments

Water quality measurement instruments are used to monitor and evaluate the physical and chemical parameters of water. They enable reliable quality control in water management, industrial operations, and other applications where accurate and continuous data are essential.

E2 - Calibration and Control Unit for the Water Supply Industry

E2 - Calibration and Control Unit for the Water Supply Industry

The Process Controller E2 is a control unit and data logger designed for the numerical and graphical display and recording of data. It acquires this data from connected sensors for dissolved oxygen, pH, REDOX potential, turbidity, conductivity, ISE, and temperature. It also calibrates these sensors and controls connected equipment using internal relays and 4–20 mA current outputs.
