CM-510: Multi Gas Handheld Detector

The Multi Gas (CO2, CO, O2, NH3) Handheld Detector is designed to measure multiple gas concentrations across a wide range of industries. With this solution, users can store data for a long period of time, analyze many gases, and set up loud alarms.


  • Audible alarms will sound if concentrations exceed normal thresholds
  • Li-ion rechargeable batteries for longevity and increased lifespan
  • Measures: CO2, CO, O2, NH3, PM2.5, PM10, Temp, RH, Barometric Pressure
  • Unlimited data logging with an SD card
