The center probe is a thin-walled stainless steel sheath, which contains a thin chromel-alumel thermocouple that is electrically insulated from the sheath but in good thermal contact. The outside probes are gold-coated copper. The probe can be reproducibly inserted into a glass bulb containing the liquid tested such that the immersion level of the probes is always the same.
