Featuring the patented Matrx "Auto-Compensation" flow and percentage feature - the MDM is the only analog display flowmeter that automatically maintains flow rate when the percentage flow is adjusted (and vice versa).

For offices preferring an at-your-side vertical flowmeter - the Matrx MDM provides the largest analog display available – allowing for easy view of glass indicator tubes. The perfect solution for offices that require low flow rates for their patients.

Single knob flow control and oxygen percentage dial allow for easy 2-step operation, and accurate delivery. Oxygen flush button conveniently located for easy access. Oxygen quick connect (optional add on) and oral surgery (high flow) model available.

Mounting options include: mobile cart, portable “E” cylinder stand, wall arm mount, and under cabinet slide mount.
