Abstract
A method of, and apparatus for, carrying out thermoanalytical investigations at low temperatures, wherein an article to be investigated is placed in a heating chamber in a furnace and there is ascertained the temperature of the article or a measurement parameter that characterizes the temperature of the article. The temperature in the furnace chamber is brought to a predetermined value by a heating control circuit and a cooling medium is taken from a tank under substantially constant pressure to control the temperature in the furnace chamber. The throughflow of cooling medium is quantitatively controlled to produce a predetermined temperature difference between the furnace chamber and the cooling medium.
