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.

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.
The chlorine sensor flow cell is designed to direct the proper sample flow past the membrane in order to ensure accurate and consistent results. This flow cell is also used with a variety of membrane-covered sensors such as free chlorine, total chlorine, chlorine dioxide, chlorite, and ozone.
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.
We at Chemtrac want our customers to better understand our products. We feel the next best thing to having an on-site demonstration of our analyzers is to be able to see a video demonstration…and become more aware of the product capabilities, and see the ease of set-up and operation.
