| Ammonia | 0–100 ppm | 0.1 ppm |
| Ammonia | 0–1000 ppm | 1 ppm |
| Butane | 0–100% LEL | 1% LEL |
| Carbon Monoxide | 0–250 ppm | 1 ppm |
| Chlorine | 0–10 ppm | 0.01 ppm |
| Hydrogen | 0–40,000 ppm | 400 ppm |
| Hydrogen Sulfide | 0–100 ppm | 0.1 ppm |
| Methane | 0–100% LEL | 1% LEL |
| Nitrogen Dioxide | 0–20 ppm | 0.1 ppm |
| Oxygen | 0–25% Volume | 0.1% Volume |
| Ozone | 0–1 ppm | 0.01 ppm |
| Sulphur Dioxide | 0–20 ppm | 0.1 ppm |
DuoIQ offers the longest battery life available in a dual-gas monitor, minimising recharge frequency and reducing operational downtime. It provides up to 60 days of continuous operation, or up to 120 days based on 8-hour work shifts, for toxic gas and oxygen monitoring.
Requiring only four charges over a two-year period and featuring recharge times of less than four hours, DuoIQ maximises device availability and productivity.
Easily replace sensor trays without returning the device to the manufacturer for servicing. The plug-and-play modular design allows users to adapt the detector to changing gas monitoring requirements quickly and efficiently.
DuoIQ supports a broad range of sensor technologies, including electrochemical, infrared (IR), Molecular Property Spectrometer (MPS™), pellistor, and long-life oxygen sensors. These technologies enable unique sensor combinations and enhanced application flexibility.
Seamless integration with Crowcon Connect provides real-time monitoring, compliance tracking, and asset management capabilities. Calibration certificates can be automatically stored and retrieved, simplifying audits and regulatory compliance processes.
Measuring just over 10 cm in height and weighing only 135 g, DuoIQ combines portability with robust performance, ensuring user comfort throughout the working day.
Equipped with Bluetooth® and Near Field Communication (NFC), DuoIQ can transfer data to Crowcon Connect through IQhub. This supports live data streaming, remote configuration, and detailed performance insights to improve safety and operational efficiency.
Intuitive single-button operation simplifies device interaction, reducing training requirements and improving accessibility for users across a wide range of applications.
