The Honeywell BW Solo CO₂ Wireless is a professional single-gas detector designed for continuous monitoring of carbon dioxide (CO₂) in potentially hazardous environments. It combines accurate CO₂ measurement with Honeywell’s serviceable BW Solo platform and Bluetooth Low Energy (BLE) wireless connectivity, making it suitable for applications where both personal gas monitoring and remote instrument visibility are important.
The CO₂ version provides a measuring range of 0–50,000 ppm (0–5.0% by volume) with a resolution of 100 ppm. The standard alarm setpoints are 5,000 ppm for the low alarm and 30,000 ppm for the high alarm. The detector can also support TWA (Time-Weighted Average) and STEL (Short-Term Exposure Limit) alarm functions, allowing alarm settings to be configured according to the requirements of the application.
The BW Solo CO₂ is designed for personal monitoring of carbon dioxide, helping alert workers when CO₂ concentrations reach potentially hazardous levels. The detector uses audible, visual and vibrating alarms, with the audible alarm rated at approximately 95 dB, providing multiple ways of notifying the wearer of an alarm condition. Its 128 × 64 pixel backlit display provides clear information about the current gas reading, alarm status and instrument condition.
Wireless connectivity
A key feature of this version is the integrated Bluetooth Low Energy (BLE) functionality. The wireless BW Solo can connect to compatible Honeywell software and mobile applications, allowing gas readings and instrument status to be transmitted wirelessly. This can provide organisations with greater visibility of worker safety and gas exposure without requiring the detector to be physically connected to a docking station for every data transfer.
The wireless detector can be used with Honeywell’s Safety Suite platform and Safety Communicator application. This allows organisations to manage detector information, monitor connected workers and handle instrument data more efficiently. The BW Solo is also compatible with the Honeywell IntelliDoX docking system for instrument management, calibration and bump testing.
Easy to service and maintain
Unlike maintenance-free detectors such as the Honeywell BW Clip, the BW Solo is designed to be serviced. The sensor, battery and sensor filter can be replaced, helping extend the useful life of the detector and reduce the need to replace the complete instrument.
Calibration can be performed manually or automatically using IntelliDoX, and the detector can be configured with calibration and bump-test reminders. The instrument also records gas and event information, supporting routine safety management and compliance documentation.
The BW Solo platform also performs self-checks of important functions including the sensor, circuitry, battery and alarm indicators. It provides a rolling 24-hour peak reading and event logging, helping users and safety managers review detector activity.
Construction and environmental protection
The Honeywell BW Solo has an IP66/IP68 ingress protection rating, making it suitable for demanding working environments where protection against dust and water is required. The instrument is compact, measuring approximately 70 × 67 × 36 mm for 1-Series sensor models and weighing approximately 103–116 g, depending on the sensor configuration.
For the CO₂ sensor, Honeywell specifies an operating temperature range of approximately -20°C to +60°C. The typical battery life for the 1-Series CO₂ configuration is approximately 2 months, so the battery condition and replacement requirements should be considered as part of the detector’s maintenance programme.
Approvals & certifications
The Honeywell BW Solo platform has a range of international certifications and approvals. Depending on the exact configuration and market, these include:
- ATEX: Sira 18ATEX2243
- IECEx: IECEx SIR 18.0058
- CE: European Conformity / ATEX
- CSA: Class I, Division 1, Groups A, B, C & D, T4; Class I, Zone 0
- ABS / marine classification: Applicable BW Solo configurations carry ABS Type Approval
- IP66/IP68: Ingress protection
- BLE wireless approvals: FCC, IC and RED requirements for applicable wireless models
⚠️ SOLAS / MED approval
This product is NOT SOLAS/MED approved.
This is an important distinction for marine customers. The fact that a detector has ATEX, IECEx or ABS certification/type approval does not by itself mean that the detector is MED/SOLAS approved.
Therefore, the Honeywell BW Solo CO₂ Wireless should not be selected where MED/SOLAS approval is specifically required. Customers purchasing portable gas detection equipment for vessels should always verify the requirements of the vessel, flag state, class society and applicable regulations before selecting the detector.
Approval summary
✓ ATEX
✓ IECEx
✓ CE
✓ CSA
✓ ABS Type Approval — applicable configuration
✓ IP66/IP68
✓ BLE wireless certifications — applicable wireless model
✗ NOT SOLAS/MED APPROVED
The Honeywell BW Solo CO₂ Wireless is therefore a professional solution for continuous carbon dioxide monitoring 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 product from your SOLAS Approved Gas Detection category.
