Place hard rock samples in an ambient temperature seawater bath to equilibrate and saturate (4–12 hr). Keep sample saturated until measurement. A bell jar/vacuum pump can aid in saturation.
NoteNOTE: Seawater bath is not necessary when using the mini-puck.
- If the surface of the split core is excessively rough, use a lap plate and grit from the Thin Section Lab to prepare a smooth surface on a split-core piece. Pieces must be at least 10 cm long.
- Equilibrate the sample and sensor together in an insulated seawater bath for at least 15 min prior to measurement. NoteNOTE: Do not submerge the puck – let the water level rise to half the depth of the puck or less.
- Secure the puck to the sample with velcro or a rubber band (Figure 2).
- Optional - Apply thermal joint compound to the side of the probe where the line source is located.

Making a Measurement
- Place the section-half or the whole-round section on the TCON insulating box and close it (Figure 3). NOTE: If you are using a needle be sure that it is on vertical position to prevent it from being crushed when the door is close.
