The HydroACT analyzer offers a wide range of customizable 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 a controller 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 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 actually need while allowing for upgrades to be performed at a later time if application requirements happen to change. The HydroACT analyzer is available in three versions. Each version offers different levels of I/O capability.

Overview
HydroACT offers a 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 multiple sensors, expansive analog and digital I/O options, and digital communication capability (Modbus or PROFIBUS). For applications needing automatic chemical feed, HydroACT can be equipped with multiple control loops configured for PID, feed forward, and/or flow pacing. Other features and options include: a high resolution color display, a customizable home screen, graphical trending of up to 4 measurements on multi-axis graphs, and data logging onto removable storage media. The versatility of the HydroACT platform allows the user to only purchase the hardware and program features that are needed at that time, while still allowing for upgrades to be easily performed at a later time if application requirements change.
