The application of an AK-10 thermocontroller developed at the All-Russia Research Institute of Physicotechnical and Radio Measurements in the temperature control system of an acoustic gas thermometer makes it possible to improve the characteristics of this system. We performed temperature measurements with the use of an MI6020T bridge and demonstrate the possibility of stabilization of temperature of the resonator at a level of 15 μK. The total standard relative uncertainty of temperature measurements in the transmission of the values of temperature from the resonator to a resistance thermometer is reduced down to 0.25 ppm.
