The SprintIR®-6S is a high-speed CO2 sensor that can take up to 20 readings per second 6 times faster than the current SprintIR®-W. Combined with the sensor board, it is suitable for applications where the capture of rapidly changing CO2 concentrations is required.


  • NDIR LED sensor measures up to 20% CO2
  • Solid state, no moving parts
  • Fast response rate - 20 readings/second
  • High speed sensing - 50 Hz
  • Sensor life expectancy: > 15 years
  • MX Board includes %RH/T and barometric pressure sensors on board
  • Vibration and shock resistant
  • Digital UART output
  • RS485 Modbus RTU with optional RS485 cable
  • Easy integration; compact & low Power


CM-20401 Development Kit – Easy to use, simply plug the sensor board into your PC via the included serial UART to USB cable. Use our free GasLab® software to measure and graph carbon dioxide (CO2).

CM-20400 CO2 Sensor on Board Board – Same functionality as the development kit without USB cable or software.

GC-0029 SprintIR®-6S Sensor Only – for integration into high-volume OEM products.

RS485 Modbus RTU Cable. Custom USB cable enables RS485 Modbus RTU communication to GasLab Software for MX Sensor Board and Development Kit.

Micro-Pump Kit includes all the tools you need to utilize the tube-cap adapters as part of a sampling sensor system.

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.
