Combined pH and Conductivity Meters


430 Enterprise Conductivity/pH Meter

• Simultaneous display of pH, conductivity and temperature
• Automatic or manual calibration
• Combined pH, conductivity and temperature probe
• Power on self check routine
• Auto-selecting ranges for both TDS and conductivity modes

The easy to use 430 is designed to readily withstand the rigours of field work, while reliably measuring pH and conductivity. The unit allows the simultaneous readout of pH, conductivity or TDS and temperature with switched ranges for both conductivity and TDS measurements.

3540 Bench Combined Conductivity/pH Meter

• Simultaneous display of pH and conductivity
• 2 independent channels to prevent interference between probes
• Additional modes for resistivity, salinity, TDS and mV
• Data logger with auto save/print options
• Storage of up to 500 readings (250 for each mode)

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.
