FIELD: instrument-making. ^ SUBSTANCE: in device for provision of thermal contrast mode in incubator, which includes timer with relay and thermally independent resistor with normally closed contact, in accordance with invention, normally closed relay contact is connected in parallel to thermally independent resistor in such a manner so that when opening it periodically connects it serially to regular thermal converter of incubator thermal controller. Besides, device is additionally equipped with sound siren, which is controlled by incubator thermal regulator. ^ EFFECT: increases stability of maintaining the parameter of incubator thermal contrast mode. ^ 2 dwg |
