BW GasAlert Quattro

The BW GasAlert Quattro is a ruggedized 4-gas monitor featuring interchangeable battery packs and a large graphic display. It simultaneously detects O2, LEL, CO, and H2S in harsh environments. With its concussion-proof housing and IntelliFlash technology, it remains a durable, compliant choice for heavy-duty utility and groundworks projects.

IntelliFlash Compliance: Features a large green LED that flashes continuously to confirm the device is bump tested, calibrated, and functioning correctly from a distance.
SureCell Sensor Performance: Utilizes field-proven sensors that provide stable and reliable readings even in high-temperature or high-humidity environments.
Flexible Power Options: Unique ability to swap between a rechargeable battery pack and an alkaline pack (3 x AA batteries) for zero downtime in the field.
Global Icon Interface: Uses an intuitive LCD with icons for bump and calibration status, making it easy for users to audit compliance regardless of language.
Rugged One-Button Design: Encased in a thick, concussion-proof boot and operated by a single button, ensuring it remains functional while wearing heavy gloves.

Full Description

The BW GasAlert Quattro is a heavy-duty multi-gas monitor engineered to withstand the most demanding conditions found in the UK civil engineering and utility sectors. While it provides comprehensive detection for Oxygen, Flammables, Carbon Monoxide, and Hydrogen Sulphide, its true strength lies in its "ruggedized" design and its unique approach to power management. The unit features an interchangeable battery system that allows a user to switch between a rechargeable lithium pack and a standard three-AA alkaline pack, ensuring the device remains operational even if a charger is forgotten or unavailable in a remote site office. Durability is at the core of the Quattro's build, featuring a high-impact, concussion-proof boot and an IP66/67 rating that allows it to survive significant drops and accidental submersion in muddy site trenches. To simplify compliance for both the worker and the supervisor, the unit utilizes IntelliFlash™ technology, which is a pulsing green LED that verifies the monitor is active and calibrated from a distance. The interface is further streamlined by a large graphic LCD that uses intuitive icons rather than complex text to show bump test and calibration status, making it accessible to a diverse workforce with minimal training. In noisy environments, the Quattro ensures the wearer is alerted through a powerful combination of a 95dB audible siren, a vibrating alarm, and six bright red LED bars. It is also fully compatible with the Sampler motorized pump for essential pre-entry atmospheric checks. When you hire or purchase the BW GasAlert Quattro from PQS Survey Ltd, you receive a unit that has been fully inspected and supplied with a fresh 6-monthly calibration certificate, ensuring your project stays on schedule and your safety paperwork is always audit-ready.

FAQs

Why is the GasAlert Quattro often chosen for confined space safety kits?

The Quattro was designed for high-intensity confined space work, monitoring O2, LEL, CO, and H2S within a concussion-proof housing. Its large LCD and high-visibility alarm bars ensure readability in the low-light conditions common in sewers and utility chambers.

What is the “IntelliFlash” feature?

IntelliFlash is a green LED that provides continuous visual confirmation of operation and compliance. Visible from up to 6 metres, it allows supervisors to verify that a monitor is active, calibrated, and bump-tested without interrupting the worker’s tasks.

How do the “Interchangeable Power Options” help avoid project delays?

The Quattro can run on either a rechargeable pack or standard AA alkaline batteries. This flexibility allows workers to swap to alkaline power immediately if the unit wasn’t charged overnight, preventing morning delays and keeping the project on schedule.

Is the unit simple enough for subcontractors to use?

Yes, the unit features a simple one-button interface for everything from power-on to zero-calibration. This ease of use is ideal for multi-contractor sites, ensuring safety compliance even for staff with minimal training or experience with gas detection equipment.

How does the unit handle cold or humid UK weather?

Using SureCell sensors, the Quattro is engineered for extreme environments with enhanced resistance to temperature and humidity fluctuations. This prevents false alarms when transitioning from a warm site office to cold, damp excavations, ensuring reliable performance in UK weather.

Can the Quattro be used for pre-entry sampling?

Yes. Compatible with manual aspirator kits or motorized pumps, the Quattro allows users to draw gas samples via probes and hoses before entry. This is a mandatory safety requirement for safe systems of work in confined spaces across the UK.

Is it compatible with automated test stations?

The Quattro is fully compatible
