USER MANUAL ExStik® CL200A Waterproof Total Residual Chlorine Tester Patent Pending Additional User Manual Translations available at www.extech.
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 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. LCD Display 3. MODE/HOLD button (store data) 4.

Getting Started Equipment Required A chlorine test requires a 20ml sample cup, a reagent tablet (see the earlier section ‘Reagent Tablet Health Hazards’ for important safety information), 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.
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 to Preserve the Electrode 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. See the earlier section ‘Reagent Tablet Health Hazards’ for important safety information. 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.
