The PCA320 analyses/controls Free and total Chlorine at a range of 0.00 to 5.00 mg/L (ppm), controls pH 0.00 to 14.00, and monitors temperature at 5°C to 75.0°C. Please see the specification table below for more details.

Chlorine, pH, ORP and Temperature analysers

The PCA family are process analysers for the continuous measurement of chlorine and temperature. Also, pH (PCA320, PCA330, PCA340) and ORP where specified. The analysers feature built in data logging, RS 485 digital output, dosing relays, and alarm relays packaged in a wall mount Nema 4 x enclosure. The PCA340 also features two analog outputs.

The PCA300 family uses DPD Colorimetric method in which N, N-Diethyl-p-phenylenediamine indicator and a buffer are mixed together with the sample. The resulting chemical reaction causes a magenta colour to form in the presence of chlorine. The colour intensity is proportional to the concentration. The colour intensity is measured photometrically (light source at a specific wavelength and a photodetector) and converted to chlorine concentration, in mg/L, which is displayed on the front panel. The sampling interval for chlorine measurement is adjustable from 3 to 90 minutes.
