The SPRINTIR-R-5 5% CO2 Sensor (formerly known as the GC-0031) is the fastest commercial CO2 sensor on the market.

Capable of measuring up to 5% 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.

  • 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.
  • 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 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.
