The Multi Gas (CO2, CO, O2, NH3) Handheld Detector is designed to measure multiple gas concentrations across a wide range of industries. This solution provides users with multi-gas analysis, long-term data storage and audible alarm settings.


  • Measures: CO2, CO, O2, NH3, PM2.5, PM10, Temp, RH, Barometric Pressure
  • Audible Alarms should concentrations exceed normal thresholds
  • UNLIMITED Data Logging with SD Card
  • Li-ion rechargeable batteries for longevity and increased lifespan


This device will NOT meet requirements for CO2 safety monitoring which requires a Fixed/Wall mounted, hard-wired alarm per the NBIC, NFPA, or IFC regulations. Refer to our CO2 Safety Products page for devices that meet your needs.
