Temperature control system

The device shown in the pictures is equipped with a two-part heating system that opens to the sides.

The chamber enables rheological measurements to be carried out under controlled temperature conditions.

System characteristics:

* Two-wing design of the heating chamber.
* Electric heating system.
* Temperature control of the sample.
* Possibility of conducting temperature studies.
* Thermally insulated chamber elements.
* Connections for the temperature control system.

If the use of an ETC chamber is confirmed, the typical temperature range may be approximately -160°C to +600°C, depending on the configuration, cooling system, and accessories used. This range is not confirmed for the offered unit.
