The Enchlor Series 8000 Series Residual Chlorine Analyzer is an amperometric instrument designed to continuously analyze the residual concentration of free or total chlorine, chlorine dioxide or potassium permanganate in water or wastewater.

System Operation

A sample of water or wastewater containing the target chemical is pumped to a reservoir in the instrument where it is fed by gravity to the amperometric-measuring cell. A pH-buffering agent is also injected into the cell. A small current is developed within the cell, the level of which is directly proportional to the concentration of the target chemical within the sample. An on-board microprocessor-based digital controller processes the output of the cell, and the residual value is displayed on the LCD readout of the instrument.

The digital controller transmits a 4-20 mAdc signal for recording or remote display and is capable of outputting a signal for residual process control via one of several modes including flow pacing and compound loop control. The dissimilar metal electrodes of the cell are continuously cleaned by PVC spheres, which are stirred within the cell by a motor driven striker. This continuous cleaning eliminates signal drift and minimizes the need for recalibration of the instrument.

Temperature compensation of the cell output is provided by a thermistor, which senses cell temperature.

All control and calibration functions are digital, and adjustments are made via the simple, user friendly, 4-pushbutton keypad on the face of the instrument. The controller display is a 2-line by 16-character backlit LCD. All operations and calibration adjustments are menu driven through this display.
