The Honeywell GasAlertMicroClip X3 O₂ + CO is a compact, lightweight and easy-to-use portable gas detector designed for simultaneous monitoring of oxygen (O₂) and carbon monoxide (CO). By combining two essential gas sensors in one instrument, it provides personal atmospheric monitoring for applications where oxygen deficiency or enrichment and carbon monoxide exposure are potential hazards.
The O₂ sensor provides a measuring range of 0–30.0% by volume, with a resolution of 0.1% O₂. The CO sensor measures from 0–500 ppm, with a resolution of 1 ppm. Alarm setpoints are user adjustable, allowing the detector to be configured according to the requirements of the application.
The GasAlertMicroClip X3 is designed for straightforward operation with one-button control and an easy-to-read LCD display showing real-time gas concentrations. When a hazardous gas concentration is detected, the instrument provides audible, visual and vibrating alarms, ensuring that the wearer receives a clear warning even in noisy or demanding working environments. The audible alarm is rated at approximately 95 dB.
Continuous monitoring & safety features
The MicroClip X3 continuously monitors the condition of its sensors, battery and internal circuitry. It also incorporates Honeywell’s IntelliFlash™ system, which provides a visual indication that the detector has passed its required bump test and is operating correctly. This allows users to quickly check the status of the instrument before entering a potentially hazardous environment.
The detector includes a range of configurable functions to support professional gas detection programmes, including confidence beep, latching alarms, calibration lock, automatic zeroing on start-up, automatic oxygen calibration and configurable bump-test intervals. The instrument can also be configured to require calibration or bump testing when these activities become overdue.
Rechargeable battery & working time
The GasAlertMicroClip X3 uses a rechargeable lithium-polymer battery and provides approximately 18 hours of operating time, with a recharge time of less than six hours. Honeywell specifies the detector for operation from approximately -20°C to +50°C, making it suitable for demanding industrial and outdoor working conditions.
The detector weighs approximately 190 g and measures around 113 × 60 × 32 mm, giving it a compact form that can be comfortably worn during a working shift. Its IP68 rating provides a high level of protection against dust and water ingress.
Calibration, bump testing & data management
The MicroClip X3 is compatible with the Honeywell IntelliDoX docking system, which can be used to perform automated bump tests and calibration. This is particularly useful for organisations managing multiple detectors and wanting to maintain a consistent inspection and calibration programme.
The detector also supports Honeywell SafetySuite for instrument management. Datalogging provides approximately 16 hours of recorded data at 15-second intervals, allowing relevant instrument and gas information to be reviewed as part of workplace safety procedures.
Long-life design
One of the advantages of the X3 version is its three-year warranty, compared with the two-year warranty of the older GasAlertMicroClip XL. Honeywell also specifies a five-year operating/sensor life for the X3 platform under the applicable conditions.
This makes the GasAlertMicroClip X3 a practical option for companies looking for a durable, rechargeable personal detector that can be maintained and managed over a longer service period.
Approvals & certifications
The Honeywell GasAlertMicroClip X3 carries recognised hazardous-area certifications, including:
- ATEX: II 1 G, Ex ia IIC T4 Ga
- IECEx: Ex ia IIC T4 Ga
- CE: European Conformity

⚠️ SOLAS / MED approval
This product is NOT SOLAS/MED approved.
This is particularly important for marine customers. ATEX, IECEx, CE and CSA certifications are hazardous-area/safety certifications and should not be presented as equivalent to SOLAS or MED approval.
For this exact GasAlertMicroClip X3 O₂ + CO product, De Wolf Maritime Safety lists:
SOLAS/MED approved: No.
Therefore, this detector should not be selected where SOLAS/MED approval is specifically required. Customers purchasing portable gas detection equipment for vessels should verify the requirements of the vessel, flag state, classification society and applicable regulations before selecting this model.
Approval summary
✓ ATEX
✓ IECEx
✓ CE
✓ CSA
✓ IP68
✓ IntelliDoX compatible
✓ Honeywell SafetySuite compatible
✗ NOT SOLAS/MED APPROVED
The Honeywell GasAlertMicroClip X3 O₂ + CO is therefore a professional and compact solution for continuous monitoring of oxygen and carbon monoxide in industrial, hazardous-area and certain marine applications where SOLAS/MED approval is not a requirement.
For vessels or applications where SOLAS/MED-approved portable gas detection is mandatory, customers should select a suitable detector from your SOLAS Approved Gas Detection category.
