Medical Gases

Test Guidelines for Medical Gas regulators, flowmeters, suction valves
(AS 3840, AS 2902, AS 2120.3 AS 2473.3)

Gas regulators, flow-meters, and suction valves, which are intended to be connected pressure regulators for the administration of medical gases, must meet the specification requirements of the Australian Standard. Confirmation that these devices are performing

accurately, reliably and within manufacturer’s specifications is a requirement for users of medical gases.

U-Tech Medical supports this Standard as can provide assistance and guidance to adopt the best management program, specifically for the devices types in your medical facility.
