For every degree change in temperature, there is approximately a 2% change in conductivity. To convert raw conductivity measurements to Specific Conductance measurements, you can use the following equation:
Specific Conductance = Conductivity / (1 + 0.02 * (temp(C) - 25))
You can also perform this calculation automatically using the Data Wizard.
You can also convert Conductivity readings to Salinity (expressed in Practical Salinity Units (PSU)) using the Data Wizard.
- Identification describes the measurement parameter of the channel and has already been configured as 'CONDUCTIVITY'. The channel can be re-named to suit each project. The Identification field will be the channel heading, data column heading and graph line name when viewing the data. Identification is limited to 32 characters.
- Unit refers to the channel's unit of measurement. There are two units of measure available for the user to select: mS/cm or μS/cm.
