Porter’s anaesthesia equipment is designed with Australia’s clinicians and medical teams in mind, giving them the capability required to achieve excellent levels of care for patients. This analogue sedation flowmeter is renowned for its ease of use, accuracy and long life span as well as its ease of maintenance and servicing. This unit is fully compliant with all Australian standards including AS2896 and AS3840 and also complies to the ADA Policy 6.17 for Conscious Sedation.

The MXR-3000 has been the most trusted and recognised flowmeter on the market, featuring Porter precision glass indicator tubes and ergonomic single motion controls. The MXR 3000 is designed for those who would prefer an at-your-side vertical flowmeter.

Another superior feature of the Porter MXR Series is the control it provides to clinicians during patient care. Clinicians can set the O2 and N2O mix ratio by regulating the N2O percentage. This enables effective sedation and anaesthesia for all patients, including paediatric care cases. The controls of the device are also more responsive than other units on the market, enabling swift dose adjustments as and when required.

Mega Medical is the licensed distributor for these products on the Australian market. ARTG Entry Number: 375145. This unit comes with a 1 year manufacturer warranty. Porter products are manufactured in Pennsylvania USA by the Parker Hannifin  Precision Fluidics Division.
