Intelligent Assistant

Provides step-by-step guidance on calibration, sample measurement, application methods, maintenance, inspection and troubleshooting.

Calibration Support Function

Enjoy hassle-free calibration with on screen support. The meter will walk you through the steps of calibration.
  • Auto Buffer Recognition
  • Auto Calibration Function

Reading Stability Check

  • Perform proper calibration with stable readings
  • Determine the stability of reading at a glance in either digital or graph display during pH and ion calibration
  • Stability value is a deviation between the maximum and minimum readings in the last 10 seconds

Electrode Status

  • Electrode condition and results such as calibrated values, offset, acid and alkaline slopes, are shown at the end of calibration
  • Programmable calibration reminder and alarm for measured values exceeding set limits
  • Temperature indicator appears when a temperature probe or electrode with integrated temperature sensor is connected to the meter
  • Electrode model, either selected from preset list or entered manually, and lot or MFG no. (entered manually) are included in stored data and printouts
  • Temperature sensor calibration function
