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.
