HYGROMETER Russian patent published in 2016 - IPC G01N25/60 

FIELD: instrument engineering.

SUBSTANCE: invention relates to analytical instrument making and is intended for measurement of moisture volume fraction in gases. Hygrometer comprises a coulometric cell, power supply and device for measuring electrolysis current. Hygrometer also includes a flow stabiliser for analysed gas, between nozzles which “Vykh” (output) and “O” (reference pressure) are connected parallel circuits of series-connected fluidic resistors and solenoid valve, “Vykh” nozzle of gas flow stabiliser is connected to a circuit of series-connected elements : fluidic resistors and solenoid valve, pneumatic reservoir and solenoid valve, pneumatic reservoir is connected to a pressure gauge with an electrical output, combined unit.

EFFECT: technical result is wider field of use of coulometric hygrometers.
