Honeywell BW™ Ultra – Multi-Gas Detector (Including CO₂)

The Honeywell BW™ Ultra is a next-generation portable five-gas detector engineered for confined space gas monitoring and sampling, ideal for shipping, marine operations, industrial vessels, and safety teams tasked with ensuring atmosphere safety before and during entry into enclosed spaces.

Meets latest IMO Requirements

Comprehensive Gas Coverage, Including CO₂

This unit simultaneously detects:

• Oxygen (O₂) — essential for confirming safe breathing air.

• Lower Explosive Limit (LEL) of flammable gases — for fire and explosion prevention.

• Hydrogen Sulphide (H₂S) — a common toxic hazard in marine and confined spaces.

• Carbon Monoxide (CO) — a lethal asphyxiant from combustion or decomposition.

• Carbon Dioxide (CO₂) — via an infrared (IR) fifth sensor option, now critical for enclosed space safety compliance (e.g., IMO’s revised atmospheric testing guidance) and for detecting asphyxiation hazards that may not show up with O₂ readings alone.

Having CO₂ detection alongside the standard four gases ensures your vessel’s gas detection program meets the latest safety expectations for confined space entry and continuous atmosphere monitoring.*

Why CO₂ Matters Now

Recent changes in marine safety standards emphasise the need to explicitly monitor CO₂ levels in enclosed spaces to protect crews from asphyxiation hazards and align with updated enclosed space entry recommendations. CO₂ can accumulate from cargo residues, decomposition, or inert gas use and may not be flagged by traditional gas detection alone making CO₂ monitoring a vital layer of protection before and during entry.

Designed for Marine and Confined-Space Safety

• Portable, ergonomic design — easy to handle for pre-entry and continuous sampling in tight quarters.

• Built-in pump — draws air actively from targeted areas without additional equipment.

• Large, intuitive display — rapid situational awareness for safety attendants and vessel crews.

• Reliable 1-Series sensor technology — fast response and long sensor life, even in harsh marine environments.

• Honeywell TouchConnect™ & Bluetooth capability — simple device configuration, data transfer and remote monitoring for enhanced safety oversight.

• Rugged and durable — IP66/68 ingress protection for harsh shipboard conditions.

• Long battery life — ideal for extended checks before and during confined space operations.

Safety & Compliance Benefits

✔ Verifies safe atmospheric conditions (including CO₂) before entry — supports risk assessments and safety permits.
✔ Essential for modern vessel confined space procedures, helping crews comply with updated enclosed space gas testing expectations.
✔ Reduces risk of hidden hazards — CO₂ monitoring prevents complacency when O₂ appears normal.
✔ Great for hole-watch teams and safety officers — clear alarms and real-time readings enhance oversight.

In Summary

The Honeywell BW™ Ultra multi-gas detector is the ideal solution for marine and enclosed space safety programs that need accurate, reliable, and compliant gas monitoring especially where CO₂ detection is now a key safety requirement. Its powerful sensor suite, ergonomic design, and connectivity features make it the right choice for vessel operators who prioritise crew safety, regulatory alignment, and peace of mind.
