Chlorine Dioxide

HydroACT Series

The HydroACT 300 Residual Chlorine Analyzer can measure free chlorine, total chlorine, chlorine dioxide, or pH, and is appropriate for compliance reporting following USEPA Method 334.0.

Because the HydroACT 300 has no moving parts and does not require any reagents or buffers, cost of ownership is low and maintenance is simple.

  • Description

    The HydroACT 300 Residual Chlorine Analyzer can measure free chlorine, total chlorine, chlorine dioxide, or pH, and is appropriate for compliance reporting following USEPA Method 334.0. Using a membraned-covered three-electrode amperometric sensor for chlorine measurment, Chemtrac’s probe design incorporates a long-lasting electrolyte solution which significantly reduces pH dependency. Because the HydroACT 300 has no moving parts and does not require any reagents or buffers, cost of ownership is low and maintenance is simple. The HydroACT 300 is available with up to three chlorine sensor inputs or one chlorine sensor input and one pH with Temp. sensor input, reducing the overall cost per sample point. Additional measurements such as Ozone, ORP, DO, and Conductivity are also available as sensor options.

    Standard Features

    Benefits

    • No reagents or moving parts
    • Appropriate for compliance reporting
    • Easy set up and maintenance
    • Intuitive menu and programming functions
    • Reduced pH dependency
    • Low purchase and ownership cost

    Chemtrac Chlorine Sensor Assembly and Setup

    Properly assembling the chlorine sensor is critical to the operation of the chlorine analyzer. This video demonstrates the appropriate way to set up the probe with the electrolyte, and the membrane cap. And this procedure also applies to other membrane-covered sensors, such as total chlorine, chlorine dioxide, chlorite, and ozone.

    WTP Prefers “Reagentless” Chlorine Analyzers

    A Water Treatment Plant in Auburn, AL has the need to monitor free chlorine onsite, as well as at remote locations in the distribution system, where they do not want to have to use reagents. They fist ordered a Chemtrac Reagent-less Free Chlorine analyzer in 2009, and have since purchased several more for other monitoring locations.
