The ExplorIR®-M-100 (formerly known as GC-0025) is a carbon dioxide gas sensor that measures up to 100% concentrations. Combined with the MX board, it provides full capability for industrial, scientific, engineering, or OEM applications.


  • NDIR LED Sensor measures up to 100% CO2
  • Best-in-class power consumption, durability
  • Built to reliably measure CO2 levels in harsh environments
  • Easy integration: compact & low power


  • EXPLORIR-M-100 Sensor Only – for integration into high-volume OEM products.
  • CM-40830 MX Board – Same functionality as the development kit without USB cable or software.
  • CM-40831 Development Kit – Easy to use, simply plug the MX Board into your PC via the included serial UART to USB cable. Use our free GasLab® software to measure and graph carbon dioxide, barometric pressure, temperature, and % relative humidity.

Gas Sensor Development Kit -  designed to seamlessly integrate with CO2Meter select gas sensors and provides customers with built-in pins for an easy drop-in solution. Also includes our free Gaslab data logging software

Tube cap adapters easily convert 20mm standard gas sensors from diffusion to sampling sensors and add the ability to measure barometric pressure, temperature and % relative humidity from the gas sample. Molded polymer. Tube cap adapters are not pre-installed. For accurate results you must mount the tube cap permanently.

Nafion Tubing is a highly selective, semi-permeable membrane to water vapor. If gases inside Nafion tubing are wetter than gases surrounding the tubing, drying will occur. If the surrounding gases are wetter, humidification will occur.

Micro Gas Sampling Pumps provide a constant flow of air across the sensor with a tube cap - perfect for bench-top testing of sensors for closed-loop sampling applications.

Probe Enclosure for Development Kits gives a strong and secure container to mount the sensor. Hydrophobic filters available for enclosure for outdoor use.

Yulia Pittel
Works great for the application!

The CO2 sensor has a large dynamic range and fast response time. I've noticed a gain error of ~30% but have subsequently calibrated the measurement by mixing various ratios of CO2 and air. Overall, the sensor is small and easy to communicate with and works excellent for our research application.

Johannes Krottmaier

A very stable sensor within the range from 0-100%. the correlation over the hole range is at 99.999%. An excellent product.

"Easy to install, easy to set up, and easy calibration - just what I was looking for."
