Part Numbers
I002055 Temperature Conductivity probe with gamma
This probe combination provides a continuous, depth-based measurement of fluid temperature and conductivity.
Both parameters can be output in absolute and in differential forms. A natural gamma detector is included for correlation purposes.
Principle of Measurement:
The temperature and conductivity sensors are located in an insulated housing at the base of the probe. During logging, borehole fluid flows freely through ports on the side and base of this housing and over the sensors. The log is recorded downwards while running into the hole to minimise fluid disturbance.
