The Jenway 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 optional 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. With ranges for Abs and Rel mV, TDS and Salinity and has 250 reading memory for each channel.
Supplied with glass combination pH electrode, glass conductivity probe with ATC (K=1), electrode stand and holder, ATC probe, BNC shorting plug, pH 4, 7 and 10 buffer sachets, UK power supply and operating instructions.
Have you considered your servicing requirements? Much like a car, scientific instruments may need a bit of care to keep them working reliably and at their most accurate.
The Camlab Service Department have over 60 years experience in scientific instrumentation. We have a number of highly qualified internal and field-based service engineers able to perform a variety of jobs including preventative maintenance servicing and calibration.
Camlab can offer yearly service contracts which include two main types of preventative maintenance/calibration services – the back to base service and an engineer visit to your site. These options are can be offered with differing turn around times depending on the instrument type and your requirements along with loan instruments if available.
A typical preventative maintenance service includes the following:
Inspection and testing of the unit
Dismantling, cleaning and inspection of the key parts
Correction of minor defects including adjustments if necessary
Reassembly and testing
Take post adjustment / cleaning readings
Supply of calibration certificate
Return of the item to you (back to base services)
