  • Description :

    Multiparameter portable water quality meter contains the 8 measurement modes. The meter is used for measuring the pH, ORP, Ion concentration, Conductivity, TDS, Salinity, Resistivity and Dissolved Oxygen of the liquids.

    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 standard (USA/NIST/DIN) or using the custom calibration solutions.
    • Automatic electrode slope display helps user decide whether to replace sensor.
    ORP Mode:
    • Single point offset calibration allows adjusting the displayed value to a known standard.
    • Relative and absolute millivolts measurement modes provide accurate ORP readings.
    Ion Mode:
    • 2 to 5 points calibration including the eight concentration calibration points can be selected.
    • Automatically recognize ion selective electrodes, does not need to specify type of ion.
    • Direct ion concentration readout simplifies the elaborate measurement process.
    • Selectable multiple concentration units include the ppm, mg/L and mol/L.
    Conductivity/TDS/Salinity/Resistivity Mode:
    • 1 to 5 points push-button calibration with automatic calibration solution recognition.
    • Selectable cell constant (0.1/1/10), normalization temperature (20/25°C), TDS conversion factor,

    seawater and practical salinity measurement modes.
    • Linear or pure water compensation improves measurement accuracy of meter.
    Dissolved Oxygen Mode:
    • 1 or 2 points calibration using the air-saturated water and zero oxygen solution.
    • Manual salinity and barometric pressure compensation improve the measurement accuracy.
    Other Features:
    • Automatic Temperature Compensation provides accurate reading over the entire range.
    • Calibration Due Reminder prompts user to calibrate the meter regularly.
    • Stability indicator automatically shows current measurement status.
    • Auto-Hold function freezes stable measured value for easy viewing and recording.
    • Manual temperature calibration corrects 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 you 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 parameters back to factory default settings.
    • 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.
