Used Dental Nitrous Oxide Flowmeter | Porter MXR 3000

The MXR 3000 is a flowmeter used to control the supply and distribution of nitrous oxide to patients to achieve conscious sedation pain relief during dental procedures. The MXR 3000 is designed for those who would prefer an at-your-side vertical flowmeter.

  • One-piece solid aluminum construction
  • Precision glass indicator tubes and ergonomic single-motion controls
  • Long life
  • Easy-to-read visual flow readings
  • Can be equipped with either a standard breathing circuit or Automatic Vacuum Switch (AVS)

When the Concentration Control knob is open, the Flow Control knob is closed, and there is no N2O flow indicated in the flow tube, the Nitrous Oxide Failsafe System will stop the flow of N2O. However, this safety feature should not be used as the primary shut off mechanism. The control knobs are for primary shut-off.

After purchase, breathing masks, tubing, and scavenger systems on used units should be replaced before use.
