Bibby Scientific 3540 pH/Conductivity Meter
 Simultaneous display of pH & Conductivity
Tabbed display screens with set-up menu options
Built in data logger with auto save/print
Additional modes for Resistivity, Salinity, TDS & mV
Automatic or manual calibration options
Two independent channels (e.g; pH &/or Conductivity)
The Model 3540 is ideal for use in water testing applications and in all laboratories where pH and conductivity analysis is required. It offers a space saving and flexible approach to the measurement of these two parameters. The bright back lit LCD has five separate tabbed screens, each accessed with the simple navigation keys. The set-up menu gives quick and easy access to the wide range of instrument, pH and conductivity measurement options.
The conductivity channel has a special ultra-pure water function which enables the temperature compensation algorithm for this exacting application. Other modes of operation enable Resistivity, Salinity and TDS measurement. The pH channel can also display mV values to 0.1mV resolution, enabling ORP/Redox measurements to be made.
The built in data logger can store up to 250 pH and conductivity readings based on manual or automatically timed triggers, as well as from stability and alarm status. Logged results can either be sent to the internal memory or via the RS232 serial port to the toptional printer. The comprehensive GLP functions include calibration reminders and status tracking, operator and sample ID management and a supervisor security code for all set-up options.
Calibration of both the pH and conductivity channels is automatic, with the option to select 1, 2 or 3 calibration points for each. Automatically recognised pH buffers conforming to the NIST, DIN and JIS standards can be overridden by manually entered values, as can the 4 automatically recognised conductivity standards. An option to calibrate the conductivity channel to a cell constant is also included for quick and simple conductivity measurements.
