FIELD: physics. ^ SUBSTANCE: variable temperature calorimetre with isothermal jacket is a metallic case with a side cover, with an isothermal jacket made in form of a cylindrical brass vessel with volume of 0.025 m3 with a tightly closing cover, filled with distilled water, outer lateral surfaces and bottom of which is coated with insulating material, for example penofol. At the bottom of the jacket there is a heater to force the jacket into mode, a temperare sensor, connected to a microprocessor programmed temperature regulating-measuring device of the TRM1 type, which regulates temperature in the isothermal jacket in accordance with a relay law, flow-type cooling device in form of a tubular heat exchanger, a heater for accurate switching the jacket into mode and a propeller mixer. ^ EFFECT: increased accuracy and wider range of detected thermal effects, intensification of the measurement process due to use of a twelve-ampoule device in the measuring calorimetric cell. ^ 2 dwg |
