Industrial Automation
Precision Gas Sensing Built for Long Term Performance
Honeywell’s 4 Series NDIR Flammable Gas Sensors are engineered to detect flammable hydrocarbons (C1–C6) with exceptional accuracy, stability, and durability. Designed for use in portable and fixed gas detectors, these sensors support safety‑critical applications across oil & gas, industrial, and chemical processing environments.
With non‑dispersive infrared (NDIR) technology, the 4 Series provides reliable performance over a long operational life—reducing maintenance, minimizing recalibration, and helping lower total cost of ownership.
Ideal for:
- Personal gas safety devices
- Portable gas detectors
- Fixed gas detection systems
- Industrial and hazardous environments
