iSense Methane, CO2 + O2 data logger

CO2Meter CO2 CH4 O2 BiogasIdeal for measuring greenhouse gases (GHG), this methane, carbon dioxide and oxygen meter and data logger lets you check these 3 gas levels in real time, or log gas levels over time in closed samples via the built-in gas sample draw pump. Use it for:

  • Greenhouse Gas (GHG) Monitoring
  • Natural Gas Processing
  • Algae-based Biogas Production
  • Fermentation Monitoring & Validation
  • Agricultural CO2 Up-take Analysis


Inside the meter is a micro-pump connected to two tubing ports. The unit can be programmed to automatically turn the pump on, draw gas from the inlet port, expel it from the discharge port, and log the CO2, O2 and CH4 values with a date/time stamp. Later, the data can be retrieved via USB connection to a computer running our free software.

In addition, the meter has a LCD display that shows the current gas levels, whether logging is turned on or off, and the percentage of memory free.

By connecting tubing to the inlet port, you can remotely sample gas, or by connecting tubing to both ports, you can create a closed-loop system and return the gas back to the source container. With the ability to store up to 15,000 measurements, the meter can record gas levels for days or weeks.


GasLab® software

CO2Meter GasLab_grandeThis device uses GasLab® software for setup, calibration, data logging, and real-time data analysis. GasLab® makes it easy to export data into a .CSV file that can be imported into any industry-standard software or spreadsheet. GasLab® runs on Windows XP or higher, and free to use with our products.
