Portable Multiparameter Water Quality Meter

Portable Multiparameter Water Quality Meter

High performance multiparameter water quality meter contains the 8 measurement modes. The meter is suitable for measuring the pH, ORP, ion concentration, conductivity, TDS, salinity, resistivity and dissolved oxygen of the samples.

  • pH Mode:
    • Portable multiparameter water quality meter is equipped with a large backlit LCD display.
    • 1 to 5 points push-button calibration with auto-buffer recognition.
    • Selectable pH buffer group (USA/NIST/DIN) or using the custom calibration solutions.
    • Automatic electrode slope display helps user decide whether to replace the pH electrode.

    ORP Mode:
    • Single point offset calibration allows adjusting the displayed value to a known standard.
    • Relative and absolute millivolt measurements provide accurate ORP readings.

    Ion Mode:
    • 2 to 5 points calibration including the eight concentration calibration points can be selected.
    • Automatically recognizes the ion selective electrode, does not need to specify type of ion.
    • Direct ion concentration readout simplifies the elaborate measurement process.
    • Selectable multiple concentration units including the ppm, mg/L and mol/L.

    Conductivity/TDS/Salinity/Resistivity Mode:
    • 1 to 5 points push-button calibration, automatically recognizes the standard solutions.
    • Linear and pure water compensations improve the measurement accuracy of meter.
    • Selectable cell constant, normalization temperature, TDS conversion factor, seawater and
      practical salinity measurement modes.

    Dissolved Oxygen Mode:
    • 1 or 2 points calibration using the air-saturated water and zero oxygen solution.
    • Manual salinity and barometric pressure compensations ensure accurate measurements. 


    Other Features:
    • Calibration Due Reminder prompts user to calibrate the meter regularly.
    • Stability indicator automatically shows current measurement status.
    • Auto-Hold function freezes stable reading for easy viewing and recording.
    • Automatic Temperature Compensation provides accurate reading over the entire range.
    • Manual temperature calibration corrects the temperature deviation.
    • Selectable temperature unit (°C or °F) meets different application requirements.
    • Automatic electrode diagnosis shows zero point offset and slope of the electrode.
    • Help message as a operational guide that helps user quickly begin using the meter.
    • System menu allows setting the 15 parameters, including the number of calibration points,
      resolution, stability condition, measurement unit, etc.
    • Reset feature automatically resumes all settings back to factory default options.
    • Expanded memory stores and recalls up to 500 readings.
    • Built-in real-time clock stamps stored data to meet GLP standard.
    • Stored data can be transferred into computer by USB communication interface.
    • Multi-mode power scheme (battery, power adapter, computer's USB port) ensures that use the meter smoothly.
