Infrared Gas Detector with Intelligent Heated Optics

Fixed Hydrocarbon Gas Detection System

The IR Plus is a dependable, durable, and exceptionally robust infrared hydrocarbon gas detector utilizing dual IR waveband technology to deliver real-time, fail-safe detection of methane, propane, and other hydrocarbon gases. Designed for use in harsh and demanding industrial environments, IR Plus combines long-term stability with rapid response and minimal maintenance.

Engineered with over 50 years of Crowcon expertise, the IR Plus offers unmatched performance even under extreme conditions. Its intelligent heated optics and STAY-CLIR hydrophobic reflectors resist dust, moisture, and corrosive chemicals, ensuring reliable operation while eliminating false alarms and unnecessary downtime.

With a fast 4-second response time, IR Plus provides critical safety information instantly. The detector maintains exceptional stability in high temperature and 100% RH condensing environments, making it ideal for heavy industrial applications where reliability is essential.

To reduce total cost of ownership, IR Plus is backed by an industry-leading 5-year warranty and supports flexible, non-intrusive testing through multiple display options. Standard output configurations including 4-20 mA analogue, RS-485 (Modbus), Local-HART, and HART over 4-20 mA ensure seamless integration with a wide range of monitoring and control systems.
