Combining methane, carbon dioxide, and propane measurements within a single compact package, this low-power dual-gas sensor provides an efficient solution for portable gas detection, biogas analysis, and industrial monitoring applications. By integrating multiple sensing channels into one device, it delivers comprehensive gas monitoring while minimizing power consumption and system complexity.

The sensor simultaneously measures methane concentrations from 0 to 100% volume, carbon dioxide from 0 to 100% volume, and includes a pre-calibrated propane range from 0 to 2% volume as standard. This multi-gas capability allows a single sensor to replace multiple sensing elements, simplifying system design and reducing overall power requirements.

Built on proven non-dispersive infrared (NDIR) technology, the sensor delivers stable, accurate measurements across demanding operating conditions. High-resolution performance supports detailed gas analysis, with methane measurement resolution reaching 0.01% volume at lower concentrations and carbon dioxide resolution of 0.01% volume within the 0–5% range. Propane measurements are provided with a resolution of 0.01% volume across the full measurement range.

Optimized for battery-powered and portable instruments, the sensor draws just 15 mA and 45 mW at 3 V. Compared with using two separate low-power sensors, the design further reduces power consumption, making it particularly suitable for remote monitoring systems and energy-conscious applications.

A dedicated biogas configuration is available for applications requiring simultaneous methane and carbon dioxide monitoring, providing an effective solution for anaerobic digestion systems, renewable energy facilities, landfill gas monitoring, and gas quality assessment.

Sensor setup and maintenance are simplified through compatibility with the Premier Configuration Unit. Users can configure operating parameters, perform calibration, log measurement data, and update firmware through the USB-powered interface. Integrated flash memory supports firmware upgrades, helping maintain long-term flexibility and system performance.

To ensure dependable operation in challenging environments, the sensor incorporates enhanced electromagnetic compatibility shielding and is available with multiple certification options, including:

• Industrial Ex d IIC Certified
• Mining M1 Certified
• UL Approved
• Non-Certified

All variants are available with EN50271 / SIL1 certified software, supporting applications that require compliance with functional safety standards.

Backed by a five-year warranty, the sensor provides a reliable long-term solution for gas detection systems used in oil and gas operations, mining equipment, renewable energy facilities, biogas production, industrial safety systems, and portable monitoring instruments.

By combining ultra-low power consumption, multi-gas capability, flexible configuration, and proven NDIR performance, this sensor delivers accurate and efficient gas monitoring in applications where power efficiency and measurement reliability are equally important.
