Cole-Parmer Jenway Model 3540 is an extensively specified conductivity, total dissolved solids (TDS), resistivity, salinity, pH and temperature meter with GLP support, 1, 2 or 3 point calibration and datalogging.

Features:

• Backlit LCD graphics readout with five, separately tabbed menu screens accessible to display pH and conductivity parameters, instrument set-up and logged results (pH and conductivity simultaneously displayed). The conductivity display can alternatively output Resistivity, Salinity or TDS values
• Ultra-pure water function enables the ideal temperature compensation algorithm for low range measurement to be selected
• Datalogging storage of up to 250 pH and conductivity readings (manual or time-triggered), with display call-up or output via RS232

General specifications:

 * Up to 19.99S maximum range available using accessory K=10 probe CU654-13.

Supplied with glass bodied combination pH electrode, separate ATC probe, glass conductivity cell (K=1) with built-in ATC, electrode stand and swing-arm holder, BNC shorting plug, pH4, pH7 and pH10 buffer sachets, instructions and 9V a.c. mains adapter requiring a 230V 50Hz supply.
