Novel multi-point monitoring device for oxygen concentration in life cabin

The invention belongs to the technical field of oxygen concentration monitoring of life cabins, and particularly relates to a novel multi-point monitoring device for oxygen concentration in a life cabin. Comprising a single chip microcomputer, a display device, a printing device, a clock circuit, a pressure transmitter, a gas flow sensor, a first oxygen sensor, a second oxygen sensor, a life cabin, a first gas sampling valve, a second gas sampling valve, a first gas flowmeter, a second gas flowmeter and an oxygen analyzer. In order to make up the influence of the temperature change of the gas to be measured on the oxygen permeation rate of the oxygen permeation membrane in the sensor in the collection gas chamber and cause the output drift of the diffusion current, the temperature sensor is placed in the gas chamber of the oxygen electrode for temperature tracking and monitoring, so that the precise temperature sensor is adopted in the gas chamber of the oxygen electrode for temperature collection; actually g
