Jenway 452201 4520 Bench Conductivity/TDS Meter

4520 conductivity meter supplied with glass conductivity probe with ATC (K=1) (027 013), electrode holder, 230v.

The 4520 is a high specification laboratory conductivity /resistivity/TDS/salinity and temperature meter that offers additional accuracy with 1, 2 or 3 point conductivity calibration across the wide measurement range of 0 to 19.99S. The dedicated “pure water” mode ensures the optimum accuracy for this difficult application.

Display

Primary display – 4½ digit. Provides direct readout in Conductivity and TDS of samples and standards. Mode annunciators – shows selected measurement mode; Conductivity or TDS. Secondary display – 3½ digit display. Provides direct readout of automatic or manual temperature. Mode annunciators – indicates temperature in °C or °F and whether the measurements are manually temperature compensated (MAN symbol). Endpoint symbol – this symbol is displayed when an endpoint has been detected. Mode tags – Each mode tag is highlighted when selected; SETUP, MODE, STATUS or RESULTS. If a double headed arrow symbol is present this indicates that the mode can be changed to an alternative option (pH/mV). Real time clock – will display either date or time. The following symbols will appear along the display: Padlock – Set up parameters security locked Notepad symbol – data logging to internal memory IrDA status Alarm indication – an Up arrow refers to Hi alarm / a Down arrow refers to Low alarm

Keypad

ESC used to switch the instrument on and to place into standby mode (only if power supply lead remains connected to the instrument). Also used to escape/exit a mode. CAL / CLR used to select and perform a calibration sequence. This key is also used to clear readings from Memory. Used to select Abs/Rel mV in mV mode. Print key  used to initiate a print. Up Arrow used for adjustment during set up, to scroll results and to toggle between mV and pH modes. Down Arrow used for adjustment during set up, to scroll results and to toggle between mV and pH modes. Left Arrow used for adjustment during set up and to move between mode tags. Right Arrow used for adjustment during set up and to move between mode tags. STO  used to accept an entered value in set-up mode and to instigate a stored reading. This key can also be used as a CAL key during calibration.
