High Resolution / Temperature / pH / mV / Conductivity / Salinity/ TDS / Resistivity Meter

	Features of the C861 Conductivity/pH meter *High resolution Conductivity and pH* Conductivity + temperature + 2 pH/mV channels Measures the full conductivity range 0.001 uS to 2000 mS/cm (3 cells needed to cover this range with cell constants 0.1, 1 and 10) Differential pH measures the pH difference between two inputs. Very accurate for low conductivity such as DI water *compensates for cell capacitance* *(replaces model C832)* Password protection of settings *Stores up to 12000 values + temp, date and time* Hold function freezes the current reading Bi directional RS232 Programmable recorder output GLP reporting built in Free software

Introduction Consort C861 high resolution Conductivity / pH meter

The C861 is a desk top (wall mount optional) conductivity and pH meter covering a the extreme ranges of the conductivity from 0.001 uS/cm to 2000 mS/cm depending on the cell constant. The unit can work with cell constants between 0.05 and 15 inverse cms. To cover the full range of the meter three separate cells would be required with cell constants of 0.1, 1.0 and 10.0 Very accurate low conductivity measurements can be achieved because of the built in capacitance compensation. The temperature compensation can be switched off for absolute measurements or referenced to 20C or 25C. The relative reading function allows you to directly measure the change in conductivity relative to some previously referenced level.
For pH measurements there are two channels and these can be used to provide diffential pH measurement. (the difference between the readings on the two channels). The same feature can be applied to the mV readings.

Electodes
