Abstract: A heater arrangement for an aerosol provision device comprises a susceptor arranged to heat aerosol generating material, wherein the susceptor is heatable by penetration with a varying magnetic field, a first wire connected to the susceptor at a first position, a second wire connected to the susceptor at a second position, wherein the second position is spaced apart from the first position, and electronic circuitry configured to determine a temperature of the susceptor at the first position based on a potential difference measured between the first wire and the second wire.
