supplying a wide range of sensors in order to cover different fields of application.

Conductivity Parameter

Connect the Conductivity probe to the BNC type connector marked in grey, while the temperature probe
must be connected to the RCA / CINCH Temp connector always on a grey background.
Conductivity is defined as the ability of the ions contained in a solution to conduct an electric current. This
parameter provides a fast and reliable indication of the quantity of ions present in a solution.
• ...how to get Conductivity?
The first Ohm's law expresses the direct proportionality in a conductor between the current intensity (I)
and the applied potential difference (V), while the resistance (R) represents its proportionality constant.
Specifically: V = R x I, the resistance is consequently R = V / I, where R = resistance (Ohm) V = voltage (Volt)
I = current (Ampere). The inverse of the resistance is defined as conductance (G) G = 1 / R and is expressed
in Siemens (S). Measuring resistance or conductance requires a measuring cell, which consists of two
opposite charge poles. The reading depends on the geometry of the measuring cell, which is described
through the constant cell parameter C = d / A expressed in cm-1 where d represents the distance between
the two electrodes in cm and A their surface in cm2. The conductance is transformed into specific
conductivity (k), which is independent of the cell configuration, multiplying it by the cell constant.
k = G x C is expressed in S / cm even if the units of measurement mS / cm are in common use
