CHARLOTTE, Mar. 23, 2026 – Honeywell (NASDAQ: HON) today introduced a new gas sensor that uses optical non-dispersive infrared (NDIR) technology to detect flammable gases, such as methane, propane and butane, in industrial settings. The NDIR Hydrocarbon Gas Sensor helps protect workers and infrastructure in industries such as mining, oil and gas, petrochemical and plastics manufacturing.
“In gas detection, the accuracy, precision and reliability of the sensing solution is crucial for worker safety,” said Carmen Becker, president of Honeywell Sensing Solutions. “Our new flammable gas sensor is an example of how Honeywell is using extensive domain expertise and introducing innovative technology to strengthen operational safety in industries critical to global infrastructure.”
The 4-Series NDIR Hydrocarbon Gas Sensor is designed to integrate into fixed and portable gas detectors carried by workers in the field, deep underground or within a processing facility. It is vital for these detectors to use advanced and accurate sensors that can alert workers to potential exposure to hazardous gases.
Because the NDIR sensor will be exposed to harsh conditions, such as dust in mines, methane leaks or extreme indoor versus outdoor temperature fluctuations, it is designed to be durable and reliable in a wide range of settings. The sensor has an integrated condensation reduction system, allowing it to clear excess moisture and maintain performance in humid environments and confined spaces like refineries.
Unlike traditional pellistor or catalytic bead sensors that can degrade or become “poisoned” in harsh environments, the NDIR sensor has high poisoning resistance, limiting the risk of sensor failure and reducing instances of false positives. With infrared technology, the NDIR sensor is also able to consume less power than traditional flammable gas sensors, extending the operational lifespan and prolonging a portable gas detector’s battery.
