The NEW SprintIR®-R 20% CO2 Sensor 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.
