FIELD: physics.
SUBSTANCE: proposed device comprises thermoelectric refrigerator built around Peltier element with freezing indenter made up of two parallel plates made from heat conducting material. Note here that cold junction of needle thermocouple is arranged between said plates with its hot junction built in the device case or chassis. Besides, proposed device comprises thermoelectric compensator for needle thermocouple, electric defrosting system, control board, thermocouple signal processor, indication and power supply unit made up of small-sized storage battery and automatic charging device.
EFFECT: fast response, reduced weight and sizes, higher reliability.
