    Chemtrac Chlorine Sensor Assembly and Setup

    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

    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.
