Jenway 3540 Combined pH and Conductivity Meters Jenway 3540 Enterprise Conductivity/pH Meter Jenway Conductivity meter 3540 Jenway pH meter 3540

• 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


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 both pH and conductivity analysis is 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.
