Crowcon UnoIQ – Rechargeable Single Gas Detector

The Crowcon UnoIQ is a rechargeable, serviceable single gas detector designed to protect workers against hazardous gases in industrial and commercial environments. Featuring replaceable, pre-calibrated sensor trays, optional Bluetooth connectivity and a rugged IP66/IP68-rated housing, the UnoIQ offers a flexible, long-term alternative to disposable personal gas detectors.

Available for monitoring carbon monoxide (CO), hydrogen sulphide (H2S), oxygen (O2), methane (CH4), carbon dioxide (CO2), nitric oxide (NO) and nitrogen dioxide (NO2), the Crowcon UnoIQ is suitable for a wide range of workplace gas detection applications.

Unlike traditional disposable gas monitors, the UnoIQ features a modular design, allowing compatible sensor trays to be replaced without returning the instrument to the manufacturer. This helps reduce equipment downtime and supports ongoing instrument maintenance.

• IP66/IP68 protection: Rugged construction designed for demanding industrial environments.

• Audible, visual and vibrating alarms: Provides clear warnings when gas alarm thresholds are reached.

• Compact and lightweight: Approximately 134g, depending on configuration, with simple one-button operation.

• 6-metre drop-tested: Designed to withstand challenging industrial working conditions.

• IQhub compatibility: Supports automated bump testing and calibration with compatible Crowcon equipment.

Which Gases Can the Crowcon UnoIQ Detect?

The Crowcon UnoIQ is available with different sensor configurations to monitor a range of hazardous gases.

ATEX hazardous-area configurations currently available:

Safe-area-only configurations currently available:

Important: CO2, NO and NO2 configurations are designated for safe-area use only and must not be used in hazardous areas requiring ATEX-certified equipment.

Other gas options, including sulphur dioxide (SO2), ammonia (NH3), chlorine (Cl2) and ozone (O3), are planned but are not currently available to order.

Each UnoIQ is configured for one selected gas. Not all sensor types are interchangeable, and any replacement or upgrade must use compatible Crowcon-approved components.

Rechargeable Gas Detection with Replaceable Sensors

One of the main advantages of the Crowcon UnoIQ is its modular, serviceable design.

Traditional disposable single gas detectors are generally replaced at the end of their operating life. In comparison, the UnoIQ uses replaceable, pre-calibrated sensor trays, allowing compatible sensor modules to be changed without returning the detector to the manufacturer.

This provides several benefits:

• Reduced instrument downtime during sensor replacement.

• Lower reliance on complete instrument replacement.

• Easier long-term management of gas detection equipment.

• A rechargeable battery instead of a single-use operating life.

• Compatibility with Crowcon's IQ range of testing and maintenance solutions.

Battery runtime varies according to the fitted sensor technology and selected configuration. Always refer to the relevant manufacturer specification for operating and charging times.

Crowcon Connect and Bluetooth Connectivity

The Crowcon UnoIQ is available with optional Bluetooth connectivity for integration with the Crowcon Connect platform.

Crowcon Connect provides digital tools for gas detection asset management, helping businesses organise equipment records, monitor their detector fleet and manage compliance information.

For organisations operating multiple portable gas detectors, connected asset management can help simplify record keeping and improve visibility of instrument maintenance requirements.

Bluetooth connectivity is optional and should be selected when ordering if required.

Calibration and Bump Testing

Regular bump testing and calibration are essential to maintaining the reliability of portable gas detectors.

The Crowcon UnoIQ supports manual bump testing and calibration, alongside automated procedures using the compatible Crowcon IQhub docking station.

The IQhub can help organisations manage multiple instruments efficiently by automating routine testing procedures and supporting the recording of maintenance and compliance information.

Gas Monitor Point also provides gas detector calibration and servicing, helping businesses maintain their equipment throughout its operating life.

Specifications, sensor availability, certifications and operating times may vary between configurations. Please confirm the requirements for your intended application before ordering.

Common Applications for the Crowcon UnoIQ

The Crowcon UnoIQ can be used for personal gas monitoring across a wide variety of industries and working environments.

• Water and wastewater treatment: Hydrogen sulphide detection around wastewater processing facilities, sewerage infrastructure and maintenance operations.

• Manufacturing and engineering: Personal monitoring for carbon monoxide and other identified gas hazards.

• Utilities and infrastructure: Portable gas detection during inspection, maintenance and repair activities.

• Chemical processing: Monitoring selected toxic gases where a suitable sensor configuration is available.

• Oil and gas: Personal methane, oxygen, carbon monoxide or hydrogen sulphide monitoring where the selected detector has suitable hazardous-area certification.

• Facilities management: Monitoring carbon monoxide and other relevant gases during maintenance activities.

• Industrial safe areas: Monitoring carbon dioxide, nitric oxide and nitrogen dioxide where the appropriate safe-area configuration is suitable.

The correct gas detector should always be selected according to the site risk assessment, target gas, measurement range and hazardous-area classification.

Frequently Asked Questions

Is the Crowcon UnoIQ rechargeable?

Yes. The Crowcon UnoIQ is a rechargeable single gas detector, removing the need to replace an entire disposable detector when its original operating life expires. Battery runtime depends on the fitted gas sensor.

Which gases can the Crowcon UnoIQ detect?

The UnoIQ is currently available for carbon monoxide (CO), hydrogen sulphide (H2S), oxygen (O2), methane (CH4), carbon dioxide (CO2), nitric oxide (NO) and nitrogen dioxide (NO2). Each instrument monitors one selected gas, and available configurations have different certification restrictions.

Is the Crowcon UnoIQ ATEX approved?

Selected Crowcon UnoIQ configurations are available with ATEX hazardous-area certification, including CO, H2S, O2 and CH4. The CO2, NO and NO2 configurations are designated for safe-area use only and should not be used in classified hazardous areas.

Can you replace the sensor in a Crowcon UnoIQ?

Yes. The UnoIQ uses replaceable, pre-calibrated sensor trays, allowing compatible sensor modules to be replaced without returning the detector to the manufacturer. Sensor compatibility must be confirmed before replacement or upgrading.

Is the Crowcon UnoIQ a disposable gas detector?

No. Unlike traditional disposable single gas detectors, the UnoIQ is rechargeable and serviceable, with replaceable sensor modules that support long-term use.

Can the Crowcon UnoIQ detect more than one gas?

The UnoIQ is designed to monitor one selected gas at a time. Its modular platform offers an upgrade path to dual gas detection using compatible Crowcon configurations. The Crowcon DuoIQ is also available for simultaneous monitoring of two gases.

Does the Crowcon UnoIQ have Bluetooth?

Bluetooth connectivity is available as an optional feature. Compatible Bluetooth-enabled configurations can connect with Crowcon Connect for digital gas detection asset management.
