FIELD: veterinary and medicine.
SUBSTANCE: portable thermostat for biological investigations includes heat insulation housing inside which working chamber is arranged. Access to working chamber is realized through heat-insulated door. Inside working chamber technological floors are arranged; length values of said floors are slightly less than size of inner space of working chamber. Said floors form air ducts. Air passing from working chamber along said floors flows around temperature pickup with the aid of electric fan and it is heated by means of electric heater. Portable thermostat also includes switching unit connected to buses of main power supply; DC amplifier, rectifier, step-down transformer.
EFFECT: simplified design, enhanced operational reliability, lowered consumption of power, material and cost of thermostat.
