Criticare Poet IQ2 8500Q Features

The Criticare Poet IQ2 8500Q agent gas monitor measures real-time concentrations of anesthetic agent gases. The device measures gases using a sidestream method. The primary module measures concentrations of CO2, N2O, and five halogenated anesthetic agents. The Poet IQ2 8500Q monitor can also measure oxygen concentrations using a galvanic cell. It comes standard with a color TFT screen with three three-waveform displays.

  • Integrated CO2/agent detector.
  • Measures carbon dioxide, nitrous oxide, and five halogenated anesthetic agents.
  • Uses proprietary High IQ technology to identify and quantify agent gases.
  • No moving parts.
  • Reduced size.
  • Reliable.
