User's Guide 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.
Meter Description CL200 Front Panel Description 1 The ExStik’s® keys have functions which change depending on the electrode attached (pH, ORP or Chlorine). Key descriptions here apply for the ExStik® with a chlorine electrode attached. 1. Battery compartment 2 3 4 5 2. LCD Display 3. MODE/HOLD button (store data) 4.

Getting Started Equipment Required A chlorine test requires a 20ml sample cup, a reagent tablet and the CL200 with a chlorine electrode attached. The optional EX006 Weighted base is a recommended accessory. Battery Activation An insulating tab is located in the battery compartment and prevents battery drain during storage. It must be removed before use. Refer to the battery replacement paragraph in the maintenance section. Measurement Procedure Sample Preparation: 1.
Storing Readings 1. Press the MODE button to store a reading. The storage location number will be displayed followed by the stored reading and the “HOLD” indicator. 2. Only one reading can be stored during the 120 second measurement cycle. 3. Press the MODE button again to return to normal operation. 4. If more than 15 readings are stored, previously stored readings (starting with number 1) will be overwritten. Recalling Stored Readings 1.
Considerations and Techniques 1. If the meter has not been used for several weeks or is new, at least two tests should be made to condition the electrode. 2. Do not touch the reagent tablets. Touching can cause contamination. 3. If the electrode has not been used for in a 24hr period, wipe the tip with a clean/dry paper towel before use. 4. Before use, wash the sample cups and the caps and then rinse them completely. 5. The CL200 should not be left in a solution while turned off.
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 Cleaning and Maintaining the Electrode The CL200 Chlorine Electrode arrives in a factory-cleaned condition and is ready to be used. The electrode will perform best and yield more stable readings after the first few tests.
