GAS CONTROL DEVICE Russian patent published in 2023 - IPC G01N27/407 G01N27/416 

FIELD: analytical instrumentation.

SUBSTANCE: portable small-sized and autonomous devices for gas analysis, used when carrying out research on gas release in sealed containers and enclosed spaces. The gas control device contains an analog-to-digital converter, a microcontroller, a power supply module, sensors for hydrogen, oxygen, pressure, as well as temperature and humidity, and a PC with the ability to connect to the microcontroller. The device according to the invention contains a non-volatile memory connected to the microcontroller, a real-time clock and a power control unit, which is connected to the power supply module, while the oxygen and hydrogen sensors are connected through conversion elements to an analog-to-digital converter, which is connected to the microcontroller connected to the pressure sensors, temperature and humidity. Holes are made in the body of the device, opposite which the sensors are located.

EFFECT: possibility of simultaneous measurement of temperature, humidity, pressure and composition of the measured multicomponent gaseous medium in hermetic volumes without changing its composition.
