FIELD: measuring equipment engineering. SUBSTANCE: for determining coefficients for thermal and temperature conductivity of hard and dispersing materials two equal heat sources of constant power are used, which act upon heat-insulated reference and probationer materials in form of limited rods. As a result of heat sources influence and temperature measuring in fixed and moveable control points speed of temperature change and average speed of temperature sensor movement are determined. EFFECT: increased precision. 1 dwg
