Crowcon DuoIQ Dual Gas Detector

Overview

The DuoIQ is a compact dual-gas monitor designed to provide versatile and reliable protection against multiple gas hazards. It combines the industry's longest rechargeable battery life with advanced sensor technologies to deliver enhanced safety and performance.

Ideal for environments where monitoring two gases is essential, DuoIQ offers a cost-effective and compact alternative to larger multi-gas detectors without compromising on capability.

Dual-Gas Detection

DuoIQ is the only dual-gas detector capable of supporting a wide range of gas combinations, offering exceptional flexibility for diverse applications while eliminating the need for bulky multi-gas devices.

Longest Rechargeable Battery Life

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.

Pre-Calibrated Sensor Trays

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.

Comprehensive Sensor Technology

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.

Optimised for Safety & Compliance

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.

Lightweight & Compact Design

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.

Bluetooth & NFC Connectivity

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.

One Button for Multiple Functions

Intuitive single-button operation simplifies device interaction, reducing training requirements and improving accessibility for users across a wide range of applications.
