SprintIR®-W CO2 Sensor

Gas Sensing Solutions' SprintIR-W is a high-speed CO2 sensor. It measures 0 to 20% CO2 concentration and comes with an optional flow-through adapter. The sensor captures 20 readings per second, which makes it ideal for high-speed sensing requirements, and for measuring rapidly changing CO2 levels.

Its low power requirement also makes it ideal for battery-powered systems, including portable, wearable, and self-powered applications. The SprintIR-W is built on the unique patented LED technology platform and optical designs of GSS. It is this solid-state technology that enables some of the best speed, power consumption, and durability in its class.

SprintIR-W is available in measurement ranges 0 to 20% concentration. The sensor caters to high-speed sensing and capture of rapidly changing CO2 levels. This includes breath analysis, analytical instrumentation, and other real-time CO2 monitoring applications. The sensor is suitable for battery applications where low power consumption is required, including wearable applications.
