The SprintIR®-R 20 (formerly known as GC-0032) is the fastest CO2 sensor in the market, currently. This sensor's main competitive advantage is its response rate, which is 2.5X faster than the original fast response NDIR CO2 Sensor, SprintIR®-6S. 

With the ability to take 50 readings per second, and measure up to 20% CO2 concentration, this CO2 sensor is ideal for high speed sensing requirements, and for measuring rapidly changing CO2 levels. 

The SprintIR®-R 20% CO2 Sensor also comes with a fitted flow-through adapter, compact design and is utilized heavily in battery power systems, portable, wearable and self-powered environments.

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

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.
