Geotech’s portable and lightweight G210 has been developed to measure piped hospital gas and leak detection in hospitals.


  • Measures 0-100% N2O
  • Measures 0-2000ppm CO2
  • Optional: 0-100% O2; 0-500ppm CO
  • User alarms


  1. Easy user calibration
  2. Quick verification of gas quality – 4 gases measured in one analyser
  3. Enables user to enter specific site and IDs for monitoring points
  4. Identifies contaminants CO and CO2
