FIELD: measuring technique.
SUBSTANCE: device comprises radiometric receiver and computing unit for calculating the thickness of the film. The device is additionally provided with the second radiometric receiver that operates at a frequency aliquant to that of the frequency of operation of the first radiometric receiver. Each of the receivers is provided with the feeder channel that has the switch of polarization and is connected with the aerial device having common mirror aerial system with funnel emitters oriented along its longitudinal axis. The plane double-sided metallized reflector is mounted in front of the mirror aerial system. The reflector is mounted for permitting rotation around the axis that is inclined to the longitudinal axis of the mirror aerial system at an angle of 45° in a plane perpendicular to the common base.
EFFECT: enhanced reliability.
