1. Easily visible LCD display and easy operation

  • Interactive touch key operation
  • A large backlight color LCD display
  • Real time ddisplay of titration curves, measured potential/pH values, sample solution temperature, titration regent consumpsion and titration elapsed time

2. A versatile titration methods

  • Six different methods are avilable
  • The titration time can be cut by using a newly developed titration control
  • The most appropriate titration conditions can be auto matically set thanks to a preminary titration

3.Convernient and practical function

  • 100 data memory back up saving each system
  • Improved titration  reliability when burette volume corrective function, pH calibration data recording function and/or pH electrode change warning function are used

4. Expandable system

  • Selection between 2 mode: single of dual system. With dual system: 2-channel measurement is possible when 2 burette is connected
  • 10 ABT-7 burete can be connected for multi-sample titration
  • The AUT-701 automatic titrator has 2 electrode input port

           Two more input ports can be provided for versatile applications of optional titration units are connected

           The optional titration units include those for potentionmetric, photometric, polarzation and electric conductivity.

  • Connection to Toa-DKK turntable relizes automatic titration process of multiple samples
  • Connection to a combination of the turntable and automatic sampling anf measuring unit realizies a full automatic system to make sample volume measurement, dilution, regent dispensing, titration and cleaning processes.
  • Connection to a electric balance makes it possible to input the weight data of powder/granular samples in to AUT-701
  • Connection to a PC simplifies data processing
  • Connection to a printer
