The ET130 natural radiation and convection study bench consists of two superimposed enclosures: one heated electrically and regulated, the other cooled by a water exchanger; the whole working under vacuum or at atmospheric pressure. The outlet of the exchanger is equipped with a thermocouple. Experimental devices make it possible to position two circular bodies (black and gray) in one or the other of these enclosures. The temperature of each body is measured by an associated thermocouple (bolometer). A vacuum pump is integrated into the bench.
