Bante900 series Multiparameter Water Quality Meter

Multiparameter Water Quality Meter



  • High-accuracy laboratory 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 diagnosis with pH slope and offset display.


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


  • 2 to 5 points calibration, containing the 8 concentration points can be selected.
  • Automatically recognizes the ion selective electrodes, does not need to specify type of ion.
  • Direct ion concentration readout simplifies the measurement process.
  • mV measurement mode can be used to calculate the ion concentration.
  • Selectable concentration units include the ppm, mg/L and mol/L.


  • 1 to 5 points push-button calibration, automatically recognizes the calibration solutions.
  • Selectable cell constant (0.1/1/10), normalization temperature (20/25°C), TDS factor, linear and pure water compensations, seawater and practical salinity measurement modes.


  • 1 or 2 points calibration using the air-saturated water or zero oxygen solution.
  • Salinity and barometric pressure compensations provide the reliable measuring results.
  • Selectable measurement unit including the mg/L, ppm, mmHg and kPa.


  • Automatic Temperature Compensation provides accurate reading over the entire range.
  • Calibration Due Reminder prompts user to calibrate the meter regularly.
  • Stability indicator shows when a measurement is recotnized as stable.
  • Auto-Hold features senses and locks the measurement endpoint.
  • Calibration report shows the details of the calibration standards and electrode slopes.
  • Setup menu allows setting the 15 parameters, including the number of calibration points, stability criteria, temperature unit, 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.
