User s Guide EXTECH INSTRUMENTS ExStik CL200 Waterproof Total Residual Chlorine Tester Patent Pending Introduction Congratulations on your purchase of the ExStik CL200 chlorine tester The CL200 is a revolutionary first of its kind measurement device that offers direct reading of Total Chlorine from 0 01 to 10 00 ppm The electrode method employed by the ExStik is approved by the U S Environmental Protection Agency EPA as an acceptable method for wastewater compliance monitoring of total chlorine For this type of electrode method a reagent tablet must be added to the measurement solution before testing The advantages of the CL200 to the user include Easy to use and maintain high accuracy self calibration and fast response The CL200 offers simultaneous Chlorine and Temperature displays and a 15 reading memory storage Careful use and maintenance will provide years of reliable service Applications The CL200 can be used wherever a measurement of the total chlorine in water is needed This is also referred to as total residual chlorine It measures the total of all chlorine present in all forms including dissolved free chlorine chloramines hyporchlorous acid and hypochlorite ion Typical applications include measurements of discharge water from water treatment plants public drinking water supplies and cooling towers and measurement of disinfectant properties in swimming pools and cooling wat
3. ate sample cups Discard the sample cup when it shows a color change Maintain the electrode by completely wiping dry and then replacing the electrode cover immediately after taking a measurement The electrode should always be stored in the dry cap Cover the connector with the clear cover whenever the electrode is removed from the meter body Gently stirring the probe in the solution for 10 seconds within the first minute of operation will accelerate the process and yield more accurate readings Do not stir after 10 seconds Troubleshooting Guide 1 If the unit appears locked it is possible that the Data Hold mode has been inadvertently accessed If the HOLD icon is displayed simply press the MODE button or turn the meter off and restart If the meter latches up and cannot be reactivated by a button press remove the batteries and restart Note that if the batteries are removed any stored readings will be lost Electrodes Types The CL200 can also measure ORP and pH To perform these tests the appropriate electrode must be acquired and connected to the ExStik When the unit is turned on it recognizes the type of electrode that is connected and displays the appropriate unit of measure 6 CL200 V6 0 06 05 Maintenance Battery Replacement 1 Twist off the battery compartment cap 2 Replace the four 4 CR2032 batteries observing polarity 3 Replace the battery compartment cap yy Cleaning and Ma
