Low-maintenance seawater dechlorination monitor introduced
California-based Electro-Chemical Devices (ECD) has introduced the Model DCA-23 Seawater Dechlorination Analyzer, a low maintenance measurement solution that requires no chemicals to monitor seawater chlorine levels accurately in a wide range of industrial process and municipal water treatment applications.
The DCA-23 is a single-purpose analyzer that monitors chlorine in seawater from 0.0 to 2.00 ppm featuring an economical, low-maintenance design that requires no chemicals. It measures the pH, temperature and total residual oxidant (TRO) of seawater and converts them into an equivalent ppm chlorine value, which is displayed to conform with existing conventions.
The device features a minimum detection limit of 0.014 ppm and a limit of quantification (LOQ) of 0.044 ppm, making the DCA-23 Analyzer suitable for monitoring in environments with the most stringent dechlorination regulations.
The DCA-23 Seawater Dechlorination Analyzer is available in five configurations:
1) Loop powered, 4-20 mA = 0.00 to 2.00 ppm Cl
2) 24VDC powered with two 4-20 mA outputs, Cl and pH
3) 24VCD powered with two 4-20 mA outputs and two alarm relays
4 ) 110 VAC powered with two 4-20 mA outputs and two alarm relays
5) 220 VAC powered with two 4-20 mA outputs and two alarm relays.
The maximum system pressure and temperature rating is 50 psig (3.44 bar) at 60°C.
