1 to 5 point ion calibration
  Dual channel ion/ion or ion/pH
  Automatic temperature compensation ion and pH measurements
  Fully GLP compliant
  Direct potentiometry (3340 and 3345)
  Full support of incremental methods (3345 only)

The 3340 and 3345 laboratory pH/ion meters offer a host of valuable features whilst retaining simplicity of operation through the use of structured menus. Both models will store up to 100 readings all of which can be recalled on the LCD screen or down loaded to a printer or PC. Details of the last calibration results are time and date stamped, thus satisfying the requirements of GLP quality assurance protocols.

The 3345 offers additional flexibility with two additional modes of ion analysis: the known addition/subtraction mode allows the determination of ion concentrations much closer to the lower detection limits of the electrodes, whilst multiple sample addition/subtraction allows measurements to be performed in dense and concentrated matrices.
