Optimize coagulation with the latest generation Streaming Current Monitor from Chemtrac. The DuraTrac 4 Streaming Current Sensor is combined with the HydroACT Analyzer to deliver state-of-the-art charge measurement capabilities for water treatment plants.
Modbus RTU, Modbus TCP, or analog outputs, allow for direct communication with SCADA systems. And the PID control option provides for direct chemical feed pump control to maintain optimum coagulant or polymer dosages.
The DT4 has a unique Signal Health Detection feature for performance troubleshooting, and the sensor probe can be rebuilt without being replaced.
In addition to streaming current, the HydroACT can also monitor pH, UV254 organics, and Turbidity (NTU), to provide a complete coagulation monitoring and control system.
