SMTS MARINE SOLUTIONS LLC presents the Honeywell BW™ Flex 4/5 Multi-Gas Detector, a compact, lightweight and intelligent portable gas monitoring solution designed to protect personnel against multiple atmospheric hazards. Featuring a choice of 14 sensor types, the BW Flex series offers flexible gas detection configurations for monitoring flammable gases, oxygen deficiency or enrichment, and toxic gases in demanding working environments. With the capability to monitor up to five gas hazards simultaneously, it is suitable for confined-space entry, vessel maintenance, ship engine rooms, offshore facilities, oil and gas installations, and industrial operations across the UAE.
Designed for reliable field operation, the Honeywell BW Flex 4/5 combines advanced sensor technology, visual and audible alarms, Bluetooth connectivity, and a rugged IP66/IP68-rated enclosure. Its compact design and intuitive single-button operation make it a practical safety instrument for marine crews, maintenance technicians, HSE personnel, industrial workers, and confined-space inspection teams. SMTS MARINE SOLUTIONS LLC supports customers looking for Honeywell BW Flex gas detection solutions in Dubai, Abu Dhabi, Sharjah, Fujairah, and other UAE industrial and maritime locations.
CO₂ Measurement and NDIR Sensor Technology
Non-Dispersive Infrared (NDIR) CO₂ Measurement Technology
The Honeywell BW Flex 4/5 incorporates an NDIR (Non-Dispersive Infrared) CO₂ sensor, specifically designed for carbon dioxide measurement. NDIR technology detects CO₂ through its characteristic infrared absorption properties, providing a dedicated measurement method for monitoring carbon dioxide concentration in the surrounding atmosphere.
Unlike combustible gas monitoring expressed as %LEL, the BW Flex CO₂ sensor measures carbon dioxide in %VOL, with a measurement range of up to 5.00% volume (50,000 ppm). This makes it suitable for applications where accurate monitoring of elevated CO₂ concentrations is important, particularly in confined spaces, enclosed machinery areas, industrial facilities and offshore environments.
High-Resolution Carbon Dioxide Monitoring
The dedicated NDIR-CO₂ sensor provides a measurement resolution of 0.01% VOL (100 ppm), allowing operators to monitor changes in carbon dioxide concentration. The configurable alarm range extends up to 5% VOL, with factory-default low and high alarm settings of 0.5% VOL (5,000 ppm) and 3.0% VOL (30,000 ppm), respectively.
These measurement capabilities support atmospheric monitoring during confined-space inspections, tank-related operations, vessel maintenance and industrial safety procedures. Alarm thresholds should always be configured according to the applicable workplace exposure limits, risk assessment and operational requirements.
Multi-Gas Detection – Monitoring Multiple Atmospheric Hazards
Beyond carbon dioxide measurement, the Honeywell BW Flex 4/5 supports a range of configurable gas sensors to address different workplace hazards. Depending on the instrument configuration, users can select from 14 sensor types covering combustible, oxygen, and toxic gas detection.
The available sensor technologies include NDIR, catalytic bead, and electrochemical sensing, allowing the instrument to be configured according to the gas hazards associated with a particular operation.
Available gas detection options include:
- Oxygen (O₂): Monitors oxygen-deficient and oxygen-enriched atmospheres during confined-space activities.
- Hydrogen Sulphide (H₂S): Detects toxic H₂S gas commonly associated with petroleum, wastewater, and certain industrial operations.
- Carbon Monoxide (CO): Monitors toxic carbon monoxide exposure in machinery spaces and industrial environments.
- Combustible Gases (LEL): Detects flammable gas hazards using catalytic bead or infrared hydrocarbon sensor options.
- Sulphur Dioxide (SO₂): Monitors toxic sulphur dioxide concentrations.
- Nitric Oxide (NO) & Nitrogen Dioxide (NO₂): Provides monitoring options for nitrogen oxide gas hazards.
- Hydrogen Cyanide (HCN) & Chlorine (Cl₂): Supports specialist toxic-gas monitoring applications.
Intelligent Alarm System & Real-Time Gas Monitoring
The Honeywell BW Flex 4/5 incorporates multiple alarm and status indication features to help workers identify hazardous gas conditions. Its visual, audible, and vibrating alarms provide alerts when configured gas concentration thresholds or instrument conditions require attention.
Key monitoring and alarm features include:
High and low gas concentration alarms
Time-Weighted Average (TWA) alarms
Short-Term Exposure Limit (STEL) alarms
Over-limit and negative-drift alerts
Audible alarm up to 95 dB
Vibrating alarm indication
IntelliFlash and SafetyTick status indicators
Single-button operation and configurable display
The instrument offers green, amber, and red status indications to help personnel identify its operating condition quickly.
Rugged Construction for Marine & Offshore Applications
Designed for demanding industrial environments, the Honeywell BW Flex 4/5 features compact construction and ingress protection rated IP66 and IP68.
Important technical specifications:
Dimensions: 108.2 × 61.5 × 43.2 mm (with alligator clip)

Self-diagnostics: Sensor and circuitry diagnostic checks
Reflex Test: Automatic analogue sensor diagnostics every 10 minutes
The available Honeywell approvals include ATEX, IECEx, CSA, MED, DNV and CE, among others. Applicable approvals must be confirmed against the exact instrument configuration and current certification documentation.
CO₂ Monitoring in Confined Spaces, Cargo Tanks & Marine Environments
Carbon dioxide accumulation can create serious occupational hazards in enclosed and poorly ventilated environments. During shipboard maintenance, cargo operations, tank inspections, and industrial cleaning activities, personnel may encounter atmospheres with elevated CO₂ concentrations.
The Honeywell BW Flex 4/5 with its NDIR CO₂ sensor provides portable carbon dioxide monitoring to help identify hazardous atmospheric conditions before and during applicable work activities.
Typical application areas include:
Marine cargo tanks and enclosed vessel compartments
Ship engine rooms and machinery spaces
Offshore platforms and production facilities
Ballast tanks and other enclosed spaces
Industrial process areas and utility rooms
Oil and gas facilities and storage installations
Confined-space inspection and maintenance operations
For safe confined-space entry, CO₂ measurement should be considered alongside oxygen, flammable gas, and other relevant toxic-gas measurements. A CO₂ reading alone does not establish that an atmosphere is safe for entry.
