LABORATORY CHARGE ANALYZER LCA-01 / LCA-02 / LCA-03 The Laboratory Charge Analyzer (LCA) is an essential coagulation optimization tool for the water treatment professional. The LCA allows the user to determine the ideal coagulant dosage needed to achieve optimum NTU and TOC reduction in less than 5 minutes typically, earning it the moniker “5 minute jar tester”. The process of finding the optimum dosage simply involves feeding in a measured volume of coagulant into the raw water sample until the reading on the LCA indicates complete charge neutralization has been obtained. Some pH adjustment may be required to achieve accurate test results. An option for pH measurement allows the user to also quickly determine the dosage rate of additives like lime or caustic when needed to raise the coagulation pH of low alkalinity waters. Titration of the coagulant and pH adjustment additives can be performed manually using the LCA-1, or with the touch of a button using the auto-titration features that come standard on models LCA-2 and LCA-3. The automatic titration feature further simplifies the testing process and helps ensure the most accurate results possible. Another very important feature is the large sample size capacity which allows the user to accurately titrate samples using undiluted coagulant (requires micropipette), which is the recommended method when feeding PACl or ACH. Chemtrac's Laboratory Charge Analyzer comes backed with 30 years of charge analysis expertise and world class customer support.
