Honeywell’s 4 Series NDIR Flammable Gas Sensors provide reliable detection of methane and other hydrocarbons (C1–C6) using precision optical sensing technology. Designed for industrial safety, these sensors offer long-term stability, low drift, and over 10 years of operational life. Environmental compensation algorithms ensure accurate readings in high humidity and temperature conditions, while digital UART communication enables seamless integration into portable and fixed detection systems. 
FEATURES:
- NDIR sensing technology for accurate hydrocarbon detection (methane through hexane).
- Detection range up to 100% LEL with fast response times (T90 ≤30 s).
- Ultra-low power consumption for extended battery life in portable devices.
- Environmental compensation for stable performance in high humidity and temperature.
- Long operational life exceeding 10 years with reduced drift and calibration needs.
- Pre-calibrated sensors with digital UART interface for simplified integration.
- Certified for hazardous environments (ATEX, IECEx) for safety-critical applications.
- Suitable for portable detectors, fixed systems, and industrial safety monitoring.
