FIELD: biotechnology.
SUBSTANCE: invention relates to biotechnology and environmental protection in the field of control of water pollution by organic substances. Proposed device comprises vessel with tested fluid composed of U-like manometer, thermostat and mixing device. One branch of pressure gauge is made in the form of vessel with valves at inlet and outlet for arrangement of contaminated water medium and air, and on surface of water medium there is absorber of carbon dioxide in vessel in glass. Second branch of the manometer is made in the form of a measuring cylindrical tube ending with a pear with a check valve, and is equipped with a measurement scale.
EFFECT: simplification of design and expansion of functions of device with possibility of measurement in mode of communication with atmosphere and in isolation from it.
