RESIDUAL OZONE ANALYZER HydroACT 300 Chemtrac's Ozone Analyzers utilize the very latest and best ozone sensors available in the world today. The membrane covered sensor is insensitive to changing pH and interference from other oxidants, uses no reagents, is extremely stable, and has a reduced maintenance requirement compared to most other Ozone sensors. Up to 3 Ozone sensors can be connected to a single HydroACT 300 analyzer, or mix and match by connecting 1 Ozone sensor along with other measurement like pH, ORP, or conductivity. BENEFITS · Stable and reliable - excellent process control · Suitable for all potable, process and salt waters · reagents or moving parts No · to 6 months between maintenance Up · to 3 months between calibration Up · Resistant to detergents in the water Residual Ozone OZONE DOSING CONTROL FOR: · Water Treatment · Cooling Towers · Hospitals · Laundry · Food Preperation · Hospitals · Secondary Ozonation · Remote Sites FEATURES · Capable of accepting up to three measurements including: Ozone, Free Chlorine, Total Chlorine, Chlorine Dioxide, Chlorite, UV254, pH & Temp, ORP, DO, Conductivity, Biofilm, TSS/NTU, and others Advanced chemical feed control features are available, including: PID, Flow Pacing, · Delay Timer, RTC, Hi / Low Limits, and Overfeed Protections · Capable of providing up to three analog outputs, up to four relays for alarming or control, and up to two digital inputs · Optical digital communications include Modbus (ASCII / RTU / TCP), PROFIBUS, or HART Chemtrac, Inc. 6991 Peachtree Industrial Boulevard, Building 600 Norcross, GA 30092 USA PH: 770.449.6233 US: 800.442.8722 FX: 770.447.0889 www.chemtrac.com
