The measuring range from 0 to 199.9mS is covered by five automatically switched ranges using a single cell. Additionally, the in-built software is able to calculate and report results as Total Dissolved Solids (T.D.S.) in mg/1, Salinity in g/1 or Resistivity in Mohms. In the T.D.S. mode the Model 4200 allows a variable factor to be applied to the measured conductivity value.

The unique measuring cell used on the 4200 is designed to cope with the harsh environments encountered in many field situations. Carefully configured solid state four plate construction guarantees a linear response over a wide conductivity range, whilst minimising the effects of electrode fouling.

The 4200 can be standardised in two ways - a cell constant from 0.015 to 19.99 can be entered when a cell of known constant is being used. Alternatively, a calibration can be executed using a solution of known conductivity by entering its value via the set-up menu. A single point calibration automatically updates and displays the cell constant value. Where measurements are to be made over a wide conductivity range, and close accuracy is of importance, the 4200 offers two or three point calibration.

Solution conductivity varies significantly with temperature. For results to be meaningful they should be reported referenced to an agreed value. The 4200 enables reference to three internationally encountered options of 18, 20 and 25°C.

The degree to which solutions change their conductivity with respect to temperature (temperature coefficient) can be directly entered through the 4200 set-up menu. Values between 0 and 4.00%/°C are available. Additionally, a "pure water" mode enacts the non-linear temperature coefficient characteristics associated with low conductivity water. The precision temperature sensing element built into the 4200 cell will correct for temperature effects between 0 and 100°C and will measure the temperature displayed in either °C or °F.
