    Description

    GMH 5430, Conductivity Meter, Waterprooft, without Probe

    • Measurement of conductivity, resistance, salinity, TDS
    • Large double display with background illumination
    • Automatic cell correction with reference solutions
    • incl. calibration protocol

    Application:
    Mobile use for:
    + industry and craft
    + measurements of waters and aquaristics, fi sh farming
    + drinking water monitoring, process control, soil measurements
    + food production and control
    + quality management
    Additional applications at laboratory:
    + medicine, pharmacy, chemistry


    Further functions:
    Cell correction
    Manually or automatically with reference solution

    Automatic temperature compensation:
    As conductivity depends strongly on temperature, each conductivity value is only valid at the corresponding temperature. Therefore the device supports temperature compensation, i.e. referring the conductivity to a reference temperature (selectable: 20 °C or 25 °C).

    Supported types of compensation:
    - nLF: Non-linear function of natural waters acc. to DIN EN 27888 (ISO 7888) (Reference temperature 25 °C)
    - Lin: adjustable linear compensation
    - off: no compensation

    Salinity measurement:
    Salinity means the sum of the concentrations of all dissolved salts in water.
    The unit is g/kg. (equals PSU = Practical Salinity Unit).

    TDS measurement (total dissolved solids)
    TDS means the mass concentration of dissolved media in a liquid. The unit is mg/l.

    GLP (Good Laboratory Practice)
    adjustable calibration intervals
