Chemtrac HydroACT DuraTrac 4 Streaming Current Sensor


The HydroACT Analyser with DuraTrac 4 Streaming Current Sensor is Chemtrac’s most reliable and accurate Streaming Current Monitor, providing unique and versatile capabilities for optimising coagulant or polymer dosing.


Product Details

With improved streaming current measurement capability, expansive I/O, state of the art chemical feed logic, and the ability to monitor additional parameters key to coagulation (e.g. pH, UV254, NTU), this revolutionary product offers a dependable, comprehensive, and scalable approach for tackling virtually any water treatment scenario. A well designed interface gives the user easy access to frequently used features like zero offset. Intelligent diagnostics, service reminders, advanced alarm features, and optional email/text alerts all work together to notify the user when service is required or when process conditions having changed sufficiently to warrant attention.


  • Capability of incorporating multiple measurements that are key to coagulation, such as pH, TSS/NTU, and UV254 organics
  • Multiple chemical feed control options with overfeed protection, start delay, setpoint ramping, and other advanced features
  • State of the art features like signal health diagnostics and pH compensation
