Use the Orion Star T940 all-in-one titrator for flexible pH, redox and ion concentration titrations including equivalence point titrations, preset pH or mV endpoint titrations plus multiple known addition (MKA) mode for automated known addition of various ions. Pair the titrator option with any of our premium ROSS pH electrodes or Orion redox and ion selective electrodes or select one of our preconfigured titrator and electrode kits for a bundled discount.

  • Accurate, reproducible results: Automating the titration workflow enables analysis to be run using the same setup parameters and calculations every time
  • Faster setup time: Setup and save electrode, titrant and titration parameters once using methods
  • Improved lab throughput: Start the titration and let the instrument run unattended
  • Reduced cost and downtime: Easily replace titrator parts to minimize maintenance downtime while long lasting electrodes reduce the cost of ownership
  • Securely document test results: View results live, in the summary table and within the 100 point data log
  • Applications database: Tested and validated preprogrammed methods can be loaded onto your titrator
  • Standard ROSS kit with 8102BNUWP ROSS Ultra pH electrode and 927007MD stainless steel ATC temperature probe is ideal for most standard pH titrations and especially preset endpoint titrations that include temperature
  • ROSS Sure-Flow kit with 8172BNWP ROSS Sure-Flow pH electrode is designed for challenging samples that can clog standard pH electrodes or that require a fast-flowing sleeve-type junction
