RA1200 Residual Chlorine Analyzer

The Eagle Microsystems Residual Analyzer is designed to continuously analyze residual levels of free chlorine in water with constant pH value. A sample of water containing chlorine is pumped to a reservoir in the instrument where it is fed by gravity to the amperometric cell containing a gold electrode and a copper counter-electrode. A small dc current is developed across the cell the level of which is proportional to the chlorine concentration in the sample.
