The SPRINTIR-R-5 (formerly known as the GC-0031) is an extremely fast and accurate sensor, benefiting from a response rate which is 2.5X faster than the SprintIR-6S®

This sensor also, takes 50 readings per second, which makes it ideal for many industries and applications requiring high-speed requirements and rapidly changing CO2 levels.

The sensor also measures up to 5% CO2 concentration and comes with a fitted flow-through adapter. The sensor's compact size can be easily utilized and integrated into detection and gas measurement systems. It also can be used in many battery-powered systems, portable handheld devices, and wearable self-powered applications.

*Based on 0.1 liters per minute flow rate and 0-10% step change in CO2 concentrations*


  • Measures up to 5% CO2 concentration
  • High-Speed Sensing and Fast Response (50hz)
  • Low power energy consumption -35mW

CM-0032-6S/R - Custom USB cable enables communication to GasLab Software for 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.
