Product Specification

COZIR-LP Low Power Low Profile Carbon Dioxide Sensor NDIR CO2 Sensor Description

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 a mbient measurement applications that require highly accurate CO₂ measurement capability.

The CozIR®-LP sensor is designed for measuring ambient levels of CO₂ from 0-1%.

The sensor also features a built-in auto-zero function that maintains CO₂ measurement accuracy over the lifetime of the product.
