8 Bench Jenway, Model 3540 Conductivity and ph Meter The Model 3540 is ideal for use in water testing applications and in all laboratories where ph and conductivity analysis is required. 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. 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. The conductivity channel has a special ultra-pure water function which enables the ideal 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 in-built 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.

11 Bench Hanna, EC-214 and EC-215 Bench Conductivity Meters Two easy to use bench conductivity meters with temperature compensation. The EC-214 compensates manually and the EC-215 automatically and both can be calibrated with a wide range of calibration solutions. Both meters cover four measurement ranges reading from de-ionised water to brine using just one probe. Supplied with EC probe and mains power transformer. Model EC-214 EC-215 Ranges 0.0 to 199.9µS/cm, 0 to 1999µS/cm, 0.00 to 19.99mS/cm, 0.0 to 199.9mS/cm (both models) Resolution 0.1µS/cm, 1µS/cm, 0.01mS/cm, 0.1mS/cm (both models) ±1% full scale (both models) Manual 1 point (both models) Temperature compensation Manual from 0 to 50 C Automatic from 0 to 50 C Dimensions (lxwxd), mm 240x182x74 (both models) Weight, kg 1.0 (both models) EC-214 Bench conductivity meter with probe and mains power transformer POA EC-215 Bench conductivity meter with probe and mains power transformer POA for EC-214 and EC Electrode holder POA µS/cm, 460ml calibration solution POA µS/cm, 460ml calibration solution POA µS/cm, 460ml calibration solution POA Laboratory Conductivity Cells Supplied with 1 metre of cable.
