Afterwards, it switches to a base flow rate (approx. 10% of the main flush rate). The nitrogen flow of the base rate is measured with a flowmeter, displayed, and monitored by a limit switch. The O2 monitoring system continuously extracts gas from the test chamber through a flame arrestor and passes it over an O2 sensor that checks the residual oxygen content of the extracted air. The gas is then returned to the test chamber through a second flame arrestor. The extraction pump is monitored by a flow rate meter. Further details can be found in the user manual from Dräger (see appendix). The gas system is currently out of operation! The technical data refer to an ambient temperature of +25 °C, Nominal voltage 400V, without test specimens, without irradiation, and without additional equipment.
