Lab Charge Analyzer 5

Introducing the New LCA5

The LCA5 is an essential coagulation optimization tool for the water treatment professional, allowing the user to quickly, and confidently, respond to rapidly changing raw water conditions.  In under 5 minutes, the coagulant dosage needed to achieve charge neutralization can be determined by either manually or automatically titrating a raw water sample with coagulant until a zero (0) charge reading is obtained.  An optional pH measurement along with automatic titration allows the LCA5 to also determine the buffer (e.g., caustic, lime) dosage in applications where pH adjustment is required due to low alkalinity conditions.  The optional buffer titration feature is also utilized in certain applications where sample pH modification may be required in order to achieve reliable charge measurement results.  Another very important feature is the large sample size capacity (up to 2 L), and integrated stirrer which further enhance accuracy, especially when titrating with undiluted coagulants.  The LCA5 also includes graphical trending of the titration, data logging with the ability to export past titration results to a USB flash drive, and instructional videos which play directly on the 7” high resolution touchscreen display.  The LCA5 comes backed with over 35 years of charge analysis expertise and world class customer support.  Speak to one of our product specialists to discuss whether the LCA is the right tool for your application.

  • Description

    Depending on your charge analysis needs, the LCA5 will be available with different options in several different configurations.

    Standard Features

    • Accommodates 1,000 to 2,000 ml sample volumes
    • Integrated sample stirrer
    • High resolution 7” capacitive touchscreen
    • Graphical trending and data logging
    • Advanced signal health diagnostics

    Optional Features

    • pH & Temperature measurement
    • Automatic titration with coagulants and buffers (1 or 2 pumps)
    • Syringe pump for neat coagulant titration
    • Protective Transport case


    • Quickly determine target coagulant dosage needed to achieve charge neutralization, allowing for optimum NTU and TOC removal
    • Assess minimum dosage of buffer needed to raise pH in low alkalinity waters to help achieve optimum coagulation
    • Large sample size, sample stirrer, and advanced signal health diagnostics ensures accurate results

    Model Configurator


    Automatic Pump Titration Configuration

    0 = No Automatic Titration

    1 = One Titrant Pump (Coagulant Only)

    2 = Two Titrant Pumps (Coagulant & Buffer)

    Syringe Pump Upgrade(1)

    0 = No

    1 = Yes

    pH with Temp(2)

    0 = No

    1 = Yes

    Example: LCA5.2201 comes with 2 automatic solenoid micro-pumps (one for coagulant and one for buffer), and also includes pH and Temperature measurement capability.

    (1): Syringe pump upgrade is required when chemical supplier states their coagulant should not be diluted, as is the case with some pre-hydrolyzed coagulants.

    (2): pH w/Temp option is required if LCA5 is configured with two titrant pumps.  Note: Some applications will require the LCA5 to have two titrant pumps for sample pH adjustment capability in order to ensure accurate results.  Contact Chemtrac for details.

  • Chemtrac to Exhibit at ACE22 in San Antonio

    The new LCA5, next generation Lab Charge Analyzer, will be featured at the Chemtrac Booth (#19095) during the upcoming AWWA ACE22 conference and exhibition, June 12 -15.

    The LCA5 allows for a target coagulant dose to be automatically determined in just a matter of minutes…much faster than can be done with conventional jar testing. This can provide for quicker response times to turbidity events, more consistent water quality, and overall chemical cost savings.

    Chemtrac will also have on display variety of analyzers including their on-line Streaming Current Monitorparticle counters, and reagentless chlorine analyzers.

    If you are going to be in San Antonio for ACE22, please be sure to stop by Booth 19095, and check out the LCA5, and the other lines of Chemtrac analyzers.
