description FIELD: measuring technique. ^ SUBSTANCE: device has pulse radiation source being optically connected with oxygen sensor provided with luminescent activator and photoreceiver. Device also has pulse radiation source power unit electrically connected with pulse radiation source. Oxygen luminescent sensor is made in form of pill of silica adsorbate; tripaflavine dye is used as luminescent activator. Output of photoreceiver device is electrically connected with dc amplifier made for operation in at least four time intervals by connecting control input of dc amplifier to output of control pulse oscillator. Output of control pulse oscillator is also connected with input of pulse radiation source power unit. Oxygen sensitivity of device is increased within area of concentrations less than 0,01% at speed of operation of 1 second and lower. ^ EFFECT: improved stability of measurements. ^ 2 dwg
