The SprintIR®-R 20% CO2 Sensor (formerly known as GC-0032) is the fastest carbon dioxide sensor on the market. Capable of measuring up to 20% CO2 levels up to 50 times a second, this sensor is designed for applications where high speed between measurements and fast response time are most important

This sensor is fitted with a standard flow-through adaptor so the CO2 gas can be passed over the optical sensor at high speed using an optional micro-pump.

The SprintIR®-R-5 uses patented NDIR solid-state LED optical technology enabling the sensor to respond to rapidly changing CO2 without compromising performance.


  • Takes 50 readings per second
  • Optional customized flow through adapters
  • Built-in auto-zero functionality
  • Digital (UART) data interface
  • RoHS and REACH compliant


  • SPRINTIR-R-20 – 20% CO2 Sensor only, for integration into high-volume OEM products.
  • CM-20420 – 20% CO2 Sensor w/ MX Board
  • CM-20421– 20% CO2 Sensor and Development Kit
  • Sensor Development Kit (CM-200) - Easy to use, simply plug the sensor into the PCB and plug it into your PC via USB. Use our free GasLab® software to measure and graph carbon dioxide or use our library of source code on Github to build your own application or for OEM batch testing/configuration. Order sensors on this page, then order the Devkit here.

We recommend that all first time users purchase both this sensor and the CM-200 Development Kit for fastest and easiest results.

Gas Sensor Development Kit (CM-200)- designed to provide customers with an easy drop-in solution. Includes our free Gaslab data logging software. Sensor sold separately.

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 provides a constant flow of air across the sensor with a tube cap - perfect for bench-top testing of sensors for closed-loop sampling applications.
