RAE Systems Combustible NDIR Sensor (0-100% LEL CH4) - C03-0962-000

The RAE Systems C03‑0962‑000‑RAE is a high‑performance nondispersive infrared (NDIR) combustible gas sensor designed to detect methane (CH₄) concentrations from 0 to 100% LEL, equivalent to up to 5% by volume. This sensor is built for use in the MultiRAE, MultiRAE Lite, and MultiRAE Pro family of portable gas detectors, providing accurate, stable, and poison‑resistant monitoring in industrial safety environments.

With a 1% LEL resolution and a rapid 30‑second response time, this sensor supports fast identification of hazardous conditions. Its infrared design eliminates catalyst poisoning concerns and ensures long‑term performance with minimal drift. The module installs quickly, allowing teams to restore full methane detection capability with minimal downtime.
