Flexible, small form-factor CO2 sensor.
The ExplorIR®-W is a small footprint low power CO2 sensor designed for applications where space is at a premium. The combination of small size, low power and high accuracy makes this sensor suitable for portable, battery powered personal safety equipment.
The ExplorIR®-W has a very wide dynamic range and is capable of measuring CO2 gas concentrations up to 100%, without compromising measurement accuracy or responsiveness. The ExplorIR®-W uses patented NDIR solid-state LED optical technology that delivers consistent and accurate CO2 measurement performance over the lifetime of the sensor.
