Bench Ion Meter
The 3345 laboratory pH/ion meter offers a host of valuable
features whilst retaining simplicity of operation through the use
of structured menus. The 3345 will store up to 100 readings all
of which can be recalled on the LCD screen or downloaded 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. Offering 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.
