CozIR®-LP CO2 Sensor


The CozIR®-LP is part of a new generation of ambient CO₂ sensors optimised for low-power applications. The CozIR®-LP uses NDIR solid-state LED optical technology to create a sensor with a small footprint and ultra-low-power consumption. This makes it ideal for a new generation of portable and battery powered ambient measurement applications that require highly accurate CO₂ measurement capability.

The sensor is designed for measuring ambient levels of CO₂ from 0-1%. The CozIR®-LP also features a built-in auto-calibration function that maintains CO₂ measurement accuracy over the lifetime of the product.
