HydroACT 300 Our most basic model meets the needs of most applications, and provides for maximum affordability when only 1 to 3 measurements are required. • Lowest purchase cost • Up to 3 measurements • Extensive chemical feed control features • Wide assortment of digital communications HydroACT 600 A more comprehensive solution than the HydroACT 300, with all the features one expects from a reliable, standalone, monitoring and control system. • Higher quality graphical display • Up to 6 measurements • Data logging and graphing • Optional remote access with email or text alerts BCHEMTRAC ANALYZER. CONTROLLER. TRANSMITTER. HydroACT Series High Quality & Scalable Solution for Water Treatment The HydroACT family of analyzers offers a wide range of capabilities to suit any user's requirements: from a basic analyzer with a single sensor and analog output, to a more comprehensive solution consisting of an analyzer with multiple sensors, several chemical feed control outputs, and digital communications ( Modbus or PROFIBUS). Other optional features include analog and digital I/O, data logging, and remote access via web server over LAN or GSM modem. The versatility of the HydroACT platform helps ensure a more affordable and flexible solution by allowing the user to purchase only the specific hardware and firmware components that they currently need, while allowing for upgrades to be performed at a later time if application requirements happen to change.

This has all the same features, and twice the capability of the HydroACT 600. ..plus a larger display. • Touchscreen display • Up to 12 measurements • Up to 8 digital inputs • Up to 12 analog outputs • Up to 16 relays • Up to 12 control loops HydroACT Series Free Chlorine Total Chlorine Chlorine Dioxide Chlorite Ozone TSS / NTU Dissolved Oxygen Biofilm Flow External Inputs Applications for HydroACT in municipal and industrial markets include: • Disinfection • Aeration • Coagulation • Liquid / Solids Separation (WWT) • Filtration • Biofilm Control • Finished Water/Distribution • Clean Liquid Contamination • RO Pretreatment • Corrosion Product Transport 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

Sensors / Parameters SENSORS Sensors Ranges Number of Available Parameters Sensors Ranges Number of Available Parameters Sensors with more than one parameter can be setup with fewer active parameters than are available. This allows more sensors to be connected to a single analyzer. As an example, a Particle Counter sensor has 6 available parameters. If just 2 are activated (e.g. Total Counts & Total ppb), this would allow the customer to connect up to 3 particle counters to a single HydroACT 600 analyzer (3 sensors x 2 parameters each = 6 parameters in total, which is the maximum...
