FIELD: devices for automatic determination of presence, location and value of leakages on sections difficult to technical inspection, particularly, in nuclear power plants, systems of treatment of highly active wastes, gas and oil pipelines, etc. SUBSTANCE: device has computer, interface, digital output port, analog-to-digital converter, decoders, analog switches, analog amplifiers and transducers. Interface provides for control of port and analog-to-digital converter from computer. Decoders control analog switches to whose outputs, measuring channels in form of series-connected transducer and analog amplifier are connected. Digital output port is connected to inputs of control of decoders, and outputs of analog switches are connected to input of analog-to-digital converter. EFFECT: increased information content and reliability of device operation with reduced labor input for invention realization. 1 dwg
