used in GC gas chromatography

unknown device but look like it is used to heat up a gas stream at controlled Temperature as It has a thermocouple head installed inside and has heating wiring and heat insulation inside.

testing: It is not tested as no expertise on the part and not having the plug.

only thermocouple prongs plugged into K type thermometer(not included in this sale) I had and showed correct room temperature as not heated.
