Abstract
An on-line calibration system for calibrating chemical monitors which monitor a selected chemical characteristics of a fluid sample stream, including a conditioning system for conditioning an influent fluid sample stream to produce a conditioned fluid sample stream having a predetermined level of the selected chemical characteristic. By exposing a sensor of the monitor to the conditioned fluid sample stream and calibrating the response of the sensor with respect to the predetermined level of the selected chemical characteristic in the conditioned fluid sample stream, this calibration system eliminates the effects on the response of the sensor of any ionic species in the fluid sample stream which do not affect the chemical characteristic being monitored. The on-line calibration system also includes a system which is selectively operable to establish first and second fluid sample stream flow paths, the first flow path providing the influent fluid sample stream to the detector for monitoring of the selected chemical characteristic, and the second flow path providing the influent fluid sample stream to the conditioning system and the conditioned fluid sample stream to the detector for calibrating the monitor.
