G200 Nitrous Oxide Monitor

The G200 is an advanced nitrous oxide monitor, N2O Analyzer. It uses a highly accurate non-dispersive IR cell providing superior stability and repeatability, with a measurement resolution of 1 ppm – full range. The range of the G200 is 0-1,000ppm N2O. The G200 N2O analyzer is designed to safety check background and breathing zone levels of N2O (0-1,000ppm).


  • Accurate verification of exposure limit breaches
  • Dual purpose background analyzer of personal analyzer
  • Leak detection for N2O storage
  • Portable
  • 0-1,000 ppm N2O, 0-10,000 in leak detection mode
  • TWA calculated
  • User settable alarms
  • Data download for graphing and reporting

The rechargeable Ni-cad battery provides 8 to 10 hours of continuous operation with a low battery indicator. It provides an effective means of monitoring occupational exposure to nitrous oxide (N2O) in hospital operating rooms, dental offices, veterinary clinics and surgical care centers. The G200 can also be used to check for leaks in medical gas pipelines.
