Multi-Parameter Measuring System for Water Treatment Works

AquaMaster is a compact measuring system for the following parameters: turbidity, pH, conductivity, Redox, dissolved oxygen and temperature. The various parameters can be combined individually. The colour touch screen of the AquaScat is the central control and display unit, as well as the connection to the host control system. Up to 8 measuring values can be transmitted. The measuring station is delivered completely pre-mounted. It requires only connecting the water inlet and water outlet. Connect – Adjust flow rate - Measure! Special attention was paid concerning maintenance. Holders and trays are integrated to leave both hands free for cleaning and calibration tasks.

• Compact, modular complete system
• Unrestricted parameter combination
• Central, integrated control unit with colour touch screen
