CTD-Diver Frequently Asked Questions

Below is a list of frequently asked questions for CTD-Diver. If you have a question that is not listed here, please contact our technical support team.


How is the specific conductivity in the CTD-Diver measured?

The specific conductivity Cs is calculated from the ‘true’ conductivity by using the following equation:


Cm = Conductivity at the temperature Tm

Cs = Conductivity at 25°C

Tm = Sample temperature in degrees Celsius

In the CTD-Diver the temperature coefficient is 1.91 %/°C and the reference temperature is 25 °C.

Could the size of the well influence the CTD-Diver if there is not much annular space?

The CTD-Diver measures the conducitivity inside a cavity. The conductivity sensor is designed such that only the conductivity of the solution inside this cavity is measured. Therefore, the well casing should not affect the measurements.
