Description

The PCA340 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. It has an analog output of (2) 4-20mA, 0-20mA for recorder or dosing. Please see the specification table below for more details.

From drinking and wastewater treatment to pool and spa sanitation, monitoring chlorine levels has an important bearing on public health. It can also help with the running efficiency for heating system and industrial applications.


Chlorine, pH, ORP and Temperature analysers


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.
