Crowcon DUOIQ Dual-Gas Monitor with Advanced Modular Sensor Technology

Dual-Gas Monitor with Advanced Modular Sensor Technology

A dual-gas detector with industry-leading battery life, modular sensors, and seamless connectivity for enhanced safety.

DuoIQ is a compact, dual-gas monitor designed to provide workers with versatile, reliable protection against multiple hazards. Built with the industry’s longest rechargeable battery life and every major sensor technology, DuoIQ provides safety in environments where detecting two gases is critical but equipment size and cost need to be optimised.

 

FEATURES & BENEFITS

• 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 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 plugand- play modular design provides flexibility to target 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 for enhanced safety and device performance.

• One button for multiple functions - Single-button operation simplifies the user experience with quick, intuitive control, reducing complexity and learning curves, while making the device more widely accessible.
