655-T pH Analyzer

655-T pH Analyzer

Industrial pH Analyzer

The industrial pH analyzer model 655-T from IC Controls gives you maximum flexibility, reliability, and ease of use.

The model 655-T is IC Controls’ industrial quality remote operational pH analyzer, designed to give maximum flexibility, reliability, and ease-of-use. The model 655-T is shipped from the factory with the pH input calibrated for measuring 0 pH to 14 pH and the output for 4 mA to 20 mA. Calibration should not be required. It has two isolated 4 mA to 20 mA outputs, two 10 A SPDT relays, plus a serial communication port. The analyzer recognizes specific pH buffers to auto-calibrate, holds output during calibration, notifies user of diagnosed sensor or analyzer faults, plus stores in memory the last 12 calibration records, 1 000 minute measurement trend, alarms, power outages, and diagnostic messages, all date and time stamped. The 655-T is one of a series of 115/230 VAC process analyzers supplied in a corrosion resistant IP65 (NEMA 4X) water- and dust-tight case.

These analyzers are also available for ORP, conductivity, dissolved oxygen and chlorine, plus as two-wire versions with an optional explosion-proof rating. In the case of pH, the analyzer measures the sensor signal corresponding to the actual pH and temperature. The analyzer conditions and digitizes the signal for maximum accuracy, and then sends it out as a digital output and/or on 4 mA to 20 mA outputs.

Model 655-T-6 is also available as a rental unit.

IC CONTROLS has incorporated intelligence into the microprocessor analyzers via the IC Netâ„¢ Advanced Intelligence Access Program. Measurements such as conductivity 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 calibration, upsets, diagnostics and more. 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 for communication or download and even keeps upset records! The last 20 upsets are recorded and date-stamped (ie: out of spec, alarm, power interruptions, etc.) Factors leading to alarm conditions are recalled and for measurement trend hundreds of data points can be accessed at user defined time intervals.

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

This analyzer supports and communicates diagnostics! Settings can be viewed, functions tested, calibration updated and remote operated from your computer terminal (Note: requires IC NetTM Advanced Intelligence Access Program). An optional Real-Time clock allows accurate tagging of events and duration even through power outages.

Every IC Controls microprocessor analyzer incorporates intelligence that enables advanced process control and the ability to communicate with ease and flexibility – all in one analyzer!
