Page 7: Effects On The Measuring Signal
Chloromax CCS142D Device description, function Effects on the measuring signal 3.2.1 pH value pH-dependency Molecular chlorine (Cl ) is present at pH values < 4. Consequently, hypochlorous acid (HOCl) and hypochlorite (OCl– remain within the range of pH 4 to 11 as components of free chlorine. - Page 8 Device description, function Chloromax CCS142D pH compensation of chlorine sensor signal To calibrate and verify the chlorine measuring system, a colorimetric reference measurement must be carried out using the DPD method. Free chlorine reacts with diethyl-p- phenylendiamine to form a red dye. The intensity of the red color increases proportionally to the chlorine content.

If the temperature has changed, a recalibration must be performed. The Chloromax CCS142D, when used with the Liquiline, enables automatic temperature compensation (ATC). In this case, the temperature does not need to remain constant, and a recalibration in the event of temperature changes is not required. - Page 10 Device description, function Chloromax CCS142D Memosens plug-in head O-ring Large anode, silver/silver chloride Gold cathode Measuring chamber Membrane cap with dirt-repellent membrane Screw cap for securing the membrane cap A0026479 2 Sensor structure Endress+Hauser...

Maintenance Chloromax CCS142D Replacing the membrane A0026509 Unscrew the measuring chamber (pos. 1). Unscrew the front screw cap (pos. 3). Remove the membrane cap (pos. 2) and replace it with a CCY14-WP replacement cartridge. Refill the measuring chamber with electrolyte CCY14-F (→ 24). -
Page 25: Storing The Sensor
Chloromax CCS142D Maintenance Refilling the electrolyte Unscrew the measuring chamber from the sensor shaft. Hold the measuring chamber at an angle and pour in approx. 7 to 8 ml (0.24 to 0.27 fl.oz) of electrolyte, up to the internal thread. -
Page 26: Reconditioning The Sensor
Maintenance Chloromax CCS142D Reconditioning the sensor Longterm operation of the sensor (> 3 months) in a chlorine-free medium, i.e. with very low sensor currents, may lead to deactivation of the sensor. This deactivation is a continuous process that results in a lower slope and longer response times. After long-term operation in a chlorine-free medium, the sensor can be reconditioned. - Page 27 Chloromax CCS142D Maintenance The sensor must not touch the liquid. Place the sensor in the gaseous phase approx. 5 to 10 mm (0.2 to 0.4 inch) above the chlorine bleach lye. The sensor current will now increase. The absolute value and the speed of increase depend on the temperature of the chlorine bleach lye.
