DEVICE FOR REPRODUCTION AND TRANSMISSION OF MASS CONCENTRATION UNITS OF OXYGEN AND HYDROGEN IN LIQUID MEDIA Russian patent published in 2015 - IPC G01W1/18 G01N27/00 

FIELD: measurement equipment.

SUBSTANCE: device for reproduction and transmission of mass concentration units of oxygen and hydrogen in liquid media is based on subsequent preparation of standard liquid solutions and determination in them of content of dissolved oxygen or hydrogen. The device includes a working chamber, a temperature control system including a thermostat and a heat exchange circuit, a standard barometer, a standard thermometer with a sensor submerged into the medium of the working chamber, and a mixer. Besides, the device is provided with oxygen and hydrogen analysers; the working chamber is designed for high gas pressure and provided with an inspection hole and mounting seats for electrochemical and optical sensors of oxygen or hydrogen analysers, to which mass concentration units of oxygen and hydrogen are transmitted. Besides, the device is provided with a supply system of gas mixtures, which consists of bottles with control gas mixtures, an inert gas bottle and a control system of flow and flow rate of control gas mixtures, which includes a gas line, a bubbler for pumping of gas mixtures to the working chamber, fine adjustment valves installed at the inlet and outlet of the working chamber.

EFFECT: enlarging functional capabilities and improving calibration accuracy of analysers.
