DuoIQ is a compact, dual-gas monitor designed to provide workers with versatile, reliable protection against multiple hazards, featuring the industry’s longest rechargeable battery life and incorporating every major sensor technology.
DuoIQ provides safety in environments where detecting two gases is critical, but equipment size and cost need to be optimised.
Dual-gas detection
The only dual-gas detector with the capability to detect a wide range of gas combinations, providing flexibility for diverse applications without the need for bulky, multi-gas devices.
Longest rechargeable battery life
DuoIQ boasts the longest battery life of any dual-gas monitor, reducing recharge frequency and operational downtime. It offers up to 60 days of continuous operation (120 days at 8-hour shifts) for toxic gas and oxygen detection, meaning it only requires charging four times in two years. Plus, it features quick recharge times (<4 hours) to maximise runtime.
Pre-calibrated sensor trays
DuoIQ’s sensor trays are easy to swap, eliminating the need to send the device back to the manufacturer for maintenance. Additionally, the plug-and-play modular design offers flexibility in targeting different gases.
Comprehensive sensor technology
DuoIQ features unique sensor combinations, made possible by its wide variety of sensor technologies, including electrochemical, infrared (IR), molecular property spectrometer (MPSTM), pellistor, and long-life oxygen (O2) sensors.
Optimised for safety & compliance
DuoIQ integrates seamlessly with Crowcon Connect for real-time monitoring, compliance tracking, and asset management, improving safety and ensuring regulatory requirements are met. Effortlessly store and retrieve calibration certificates in Crowcon Connect to simplify audits.
Lightweight, compact design
With its compact design, DuoIQ delivers reliable performance in a lightweight form – measuring just over 10cm in height and weighing only 135g**, ensuring portability and ease of use.
Bluetooth & NFC connectivity
With Bluetooth and Near Field Communication (NFC) connectivity, DuoIQ can push data to Crowcon Connect via IQhub. This enables live data streaming, remote configuration, and detailed insights, providing enhanced safety and improved device performance.
One button for multiple functions
Single-button operation simplifies the user experience with quick, intuitive control, reducing complexity and the learning curve, while making the device more accessible to a wider audience.
