The Matrx RA is a Relative Analgesia (non-mixing) flowmeter with a built in fail-safe that guarantees a minimum flow of 3 lpm of oxygen.
For offices preferring an at-your-side vertical flowmeter - the Matrx RA provides a large analog display – allowing for easy view of glass indicator tubes.
Separate controls for manual adjustment of oxygen and nitrous oxide flows allow the user to calculate desired percentages of oxygen and nitrous oxide. On/Off switch and oxygen flush 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.
