Jenway 3540 pH/Conductivity Meter

Jenway 3540 pH/Conductivity Meter

The Jenway 3540 pH/Conductivity Meter 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.

Jenway 3540 Key Features

• 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 conductivity channel includes a dedicated ultra-pure water mode that applies a specialized temperature compensation algorithm for high-accuracy measurements. It also supports Resistivity, Salinity, and TDS measurements. The pH channel displays mV values with 0.1 mV resolution, allowing users to perform accurate ORP/Redox measurements.

The built-in data logger stores up to 250 pH and conductivity readings using manual or automatic timed logging. Users can also log readings based on stability or alarm status. The instrument saves results to its internal memory or transfers them to an optional printer through the RS232 serial port. Comprehensive GLP features include calibration reminders, calibration status tracking, operator and sample ID management, and a supervisor security code that protects all setup options.

The meter automatically calibrates both the pH and conductivity channels. Users can choose one, two, or three calibration points for each channel. The instrument automatically recognizes pH buffers that comply with NIST, DIN, and JIS standards, while also allowing users to enter custom buffer values manually. It also recognizes four standard conductivity solutions automatically, and users can calibrate the conductivity channel by entering a cell constant for fast and accurate conductivity measurements.
