Portable pH/Ion Meter PI-320

Portable pH/Ion Meter PI-320

Professional portable pH/Ion meter contains 3 measurement modes. The meter is suitable for measuring the pH, ORP and ion concentration of liquids.

  • Ion Mode:
    • Multiparameter portable ion meter is equipped with a large backlit LCD display.
    • 2 to 5 points calibration, including the 8 concentration points can be selected.
    • Automatically recognizes the ion selective electrodes, does not need to specify type of ion.
    • Automatic electrode diagnosis shows the details of the calibration points and slopes.
    • Direct ion concentration readout simplifies the measurement process.
    • Selectable concentration units, including the ppm, mg/L and mol/L.

    pH Mode:
    • 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 diagnosis with pH slope and offset display.
    • Automatic Temperature Compensation provides accurate reading over the entire range.

    ORP Mode:
    • 1 point offset calibration allows adjusting the displayed value to a known standard.
    • Relative and absolute millivolt modes provide the reliable ORP measurements.

    Other Features:
    • Calibration Due Alarm prompts user to calibrate the meter regularly.
    • Stability indicator shows when a measurement is recognized as stable.
    • Auto-Hold feature senses and locks the measurement endpoint.
    • Battery indicator shows the remaining battery capacity.
    • Auto-Power Off effectively conserves battery life.
    • Setup menu allows setting the 10 parameters, including the number of calibration points,
      resolution, stability criteria, ionic valency, temperature unit, date and time, etc.
    • Reset feature automatically resumes all settings back to factory default options.
    • Expanded memory stores and recalls up to 500 data sets.
    • Stored readings can be transferred into the computer by USB communication interface.
    • Multi-mode power scheme (batteries, power adapter or USB port) ensures that use the meter smoothly.
