3540
Part code: 354 001
Bench Combined Conductivity/pH Meter
The 3540 is ideal for use in all laboratories where pH and
conductivity analyses are required. The setup menu gives quick
and easy access to the whole range of instrument, pH and
conductivity measurement options. Calibration of both channels
is automatic, with the option to select 1, 2 or 3 calibration points.
The pH channel can also display mV values if required.
