An award-winning, compact dual-gas monitor with modular sensor trays, industry-leading battery life, and Bluetooth/NFC connectivity for versatile worker protection in demanding oilfield environments.
The Crowcon DuoIQ is a dual-gas monitor designed to deliver versatile, reliable worker protection where detecting two gases simultaneously is critical — without the bulk or cost of a full multi-gas device. Boasting one of the longest battery lives in its class at up to 20 days on 8-hour shifts, swappable pre-calibrated sensor trays, and single-button operation, the DuoIQ is built for the field. It connects seamlessly to the Crowcon Connect cloud platform via Bluetooth and NFC through the IQhub dock, enabling live data streaming, automated bump testing, calibration certificate storage, and full compliance reporting. The DuoIQ is the only dual-gas detector with the breadth of gas combinations made possible by its full suite of sensor technologies — electrochemical, infrared (IR), pellistor, and long-life O2 — and was recognized as a Red Dot Award winner in 2026.
