Automatic Potentiometric Titrators

Automatic Potentiometric Titrators

Large color TFT-LCD with a touch panel (8.4-inch) enables easy key entry.
Up to 4 titrators , MKV-710B Volumetric, MKC-710B Coulometric or MKH-710/2nd Hybrid Karl Fischer moisture titrators or additional AT-710B potentiometric titrators , can be connected and simultaneous measurement is possible.
Monitoring temperature during titration ensures safe measurements.


  • Titrant Information is stored in an IC chip in the burette unit (Smart burette)
  • Information stored in the electrode cable (Smart electrode)
  • New burette unit
  • Up to 4 simultaneous measurements (Simultaneous titration)
  • Can be connected to MKV-710B Volumetric, MKC-710B Coulometric or MKH-710/2nd Hybrid Karl Fischer moisture Titrator
  • The main control unit and a titrator are separately located by wireless(Bluetooth(R))
  • Large color TFT-LCD with a touch panel(8.4-inch)
  • Two different user levels and permisions
  • Two different potentials , such as pH/ transmittance , pH/ conductivity or pH/ temperature can be logged simultaneously.
  • Monitoring temperature during titration ensures safe measurements
  • Measurement results are converted to PDF and can be stored in a USB flash drive
