IC Controls has incorporated intelligence into the microprocessor analyzers, which can be accessed using the optional IC Net™ Advanced Intelligence Access Program. Measurements such as chlorine can be critical to your process and must be strictly monitored and maintained. Analyzer intelligence goes beyond measurement and control; it provides the user with all necessary historical data, including events such as calibrations and diagnostics. This information can be communicated for trending or advanced control, even to remote locations. Ultimately, the user has superior control with a competitive advantage.

The analyzer stores the last 12 monthly calibration records. The last 20 upsets are recorded and date-stamped, e.g. out of spec events, alarms and power interruptions. Internal data logging capability can record hundreds of data points at user-defined time intervals for later recall of factors leading to alarm conditions and for analyzing measurement trends. An optional real-time clock allows accurate tagging of events and duration even through power outages.

The IC Net™ Intelligence Access Program runs in your Windows-based computer using RS485/RS232 and can provide you access to multiple analyzers.
