Mettler Toldeo* S70 High Performance Conductivity Meter

Advanced conductivity meter for more complex laboratory applications. Measures conductivity, resistivity, TDS, salinity; simultaneously displays measurement and temperature. Stores up to last 10 calibrations, 10 methods, and 1000 measurement/temperature data pairs. Meter offers auto read, manual read, and timed read with autoranging resolution. Endpoints can be auto or timed; high/low alarms alert the operator. Readings can be taken at preset intervals with values output to PC/printer/memory at defined periods. Design enables future expansion with modular color-coded pH, conductivity, ISE, ISFET units for enhanced capabilities.
Display: Back-lit display has online user help and GLP menus. Graphically presents calibration curve and displays last 25 readings with high/low endpoints. Automatically indicates when reading has stabilized and is ready; freeze display functions are manually controlled. Includes clock to save last 1000 data pairs with date and time.
Temperature: Manual (-30� to +130�C) or automatic (-5� to +130�C) temperature compensation. Temperature reference is selectable (20�C or 25�C) with choice of linear, nonlinear, or no correction. One-point calibration has auto buffer recognition/prompting or buffer selection (84 �S/cm, 1413 �S/cm, 12.88 mS/cm, custom standard saturated NaCl). Output cell constant after calibration. Editable cell constant. Calibration reminder is operator defined-�simply input number of use or time.
Operator can key in alphanumeric input of meter ID, user name, sample ID, sensor ID, and serial number with the security of password protection. Self-diagnostics test ensures meter is operating properly; also features power loss memory protection for worry-free data storage. Mini-DIN, 2 mm pin, and ATC power inputs. Enhanced communication through bidirectional RS232 interface supports barcode reader for sample or sensor ID.
Electrical requirements: 120V, 50/60 Hz. Operates on 9V power supply. Meter comes with the 9V power supply, electrode holder, and operating instructions.
Meter kit includes meter, 9V power supply, electrode holder, operating instructions, InLab* 730 conductivity probe and two 12.88 mS/cm and two 1413 �S/cm 20 ml conductivity calibration sachets.
Two-year warranty on meter.
