ENS190 NDIR CO₂ Sensor

ENS190 NDIR CO2 Sensor

The ENS190 is a high-performance, non-dispersive infrared (NDIR) CO₂ sensor designed for precise and reliable carbon dioxide measurement.

At the core of the ENS190 is its patented “M-shaped” long optical path gas chamber, a uniquely engineered design that maximizes the effective optical path within a compact air cavity.

This innovation, combined with a self-developed fully automated high-precision calibration system, ensures exceptional accuracy, consistency, and a wide measurement range.

With its advanced sensing capabilities and robust design, the ENS190 provides a solution for applications demanding high-precision CO₂ monitoring.

It complies with key regulatory standards such as WELL, RESET, California Title 24, and latest ANSI/ASHRAE Addendum d to Standard 62.1-2022.
