    Main features

    Save 100 measurement data
    Automatic power saving and self-diagnosis possible
    Fast print (complete within 1-2 seconds)
    Full-function all-in-one/convenient to carry
    Save 100 measurement data
    All equipment needed for measurement is stored in the case, making it convenient to carry and use (
    using a carrying case) .
    Convenience of operation (conversation method)
    From calibration to measurement and PRINT, everything is done in a conversational manner, so there is no difficulty in operation.
    Use of graphic LCD/Korean display (Display)
    Standard equipment for printing
    Calibration value, measured concentration, measuring power, total amount, temperature, and date
    are automatically printed in a given format.
    Large LCD display screen
    Using a large 64×128 dot LCD display that cannot be seen in existing chloride meters,
    data values ​​can be viewed at a glance even during calibration or measurement.
    3Power method
    When using indoors for a long time, you can use AC (110V~220V) charging power (battery) at the site , and when
    the battery is discharged, you can use the vehicle power supply to charge it.
    Self-diagnosis function
    The CPU has a self-diagnosis function to monitor the status of the device and
    displays the status when an error occurs, making it convenient to use.
    Evaluation as an excellent domestic technology
    Received certification as Korea’s first new technology (NT) and excellent quality product (EM) from the Ministry of Commerce, Industry and Energy’s Agency for Technology and Standards and an evaluation company .

    evaluation criteria [Material 55570-97]     

    Regarding the measurement of chloride in ready-mixed concrete water, the performance evaluation
    calibration solution of the measuring instrument
    is calibrated to 0.1% and 0.5% based on the chlorine ion concentration of the aqueous solution.
    The range of chloride measurement concentration is
    0.001~1.0% (CL% Water) of chloride ion concentration in aqueous solution .
    The error of the measured value
    is 0.1~0.5% (CL% Water) of chlorine ion concentration in aqueous solution and
    should be within ±10% of the standard value.
    The measured value
    must be measured simply and within a short period of time. Evaluate availability of data with reliability and reproducibility
    in the field

     

    Measurement principle
    This equipment uses a chloride ion sensor
    to generate a potential ratio by selecting chloride ions present in the aqueous solvent using a chloride ion electrode dissolved in the aqueous solvent.
