Honeywell BW Flex 4 is a portable multi-gas detector that offers a high level of flexibility and reliability for use in a wide range of hazardous environments. It can be configured to detect up to four different gases simultaneously.

 

Description

With a choice of 12 different sensor types, the BW™ Flex protects you from multiple gas hazards, in a small, rugged, and easy to use device. BW™ Flex keeps specialists operating in confined spaces, or general workers on a plant, safe from gas hazards while making safety compliance for the business easy.

The BW Flex 4 by Honeywell is a compact, high-performance multi-gas detector designed for maximum safety and versatility in hazardous environments. It supports up to four gas sensors simultaneously and can be configured with a selection of 12 sensor types, including both standard and exotic gas options. Standard sensors include Hydrocarbon NDIR, Flammable Catalytic Bead (filtered and unfiltered), Oxygen (electrochemical and lead-free), Hydrogen Sulphide, Carbon Monoxide, and Sulphur Dioxide. For more specialised applications, exotic gas sensors are available for Carbon Dioxide (NDIR), Nitrogen Monoxide, Nitrogen Dioxide, Carbon Monoxide (low hydrogen response), Chlorine, and Hydrogen Cyanide.

One of the standout features of the BW Flex 4 is its versatile sensor selection, which allows it to be configured for use in a wide range of industries, including oil and gas, construction, utilities, and manufacturing. Whether monitoring for combustible gases, toxic gases, or oxygen depletion, the Flex 4 provides the flexibility and reliability needed in dynamic work environments. At the core of the BW Flex 4 are i-Series intelligent sensors, which offer predictive calibration, maintenance scheduling, and end-of-life detection. This smart functionality significantly reduces the risk of unexpected sensor failures and ensures that gas readings remain accurate over time, boosting both safety and uptime.

To support real-time decision-making, the Flex 4 is equipped with a large, high-resolution display. This screen clearly displays gas readings at a glance and supports multiple languages, making it suitable for global operations where multilingual teams are involved. Visual clarity and accessibility are key benefits that enhance safety and ease of use in the field. Adding to its modern design, the BW Flex 4 includes Bluetooth connectivity, enabling seamless pairing with smartphones or tablets. This allows users to remotely monitor gas levels, log data, and receive alerts, which is particularly useful for lone workers or teams operating in confined or hard-to-reach spaces.

In terms of endurance, the BW Flex 4 delivers with a battery life of up to 24 hours on a single charge. This long runtime makes it ideal for extended shifts, continuous use, or deployment in remote sites where charging opportunities are limited. The BW Flex 4 brings several key benefits to the workplace. Its ability to detect multiple gases simultaneously, paired with advanced sensor technology, ensures that workers are alerted to potential hazards early—helping to prevent accidents and injuries. Intelligent diagnostics and predictive maintenance features also help reduce downtime and maintenance costs, while Bluetooth connectivity and long battery life boost operational efficiency.

Each standard BW Flex 4 package includes the detector (complete with sensors), a stainless steel alligator clip for secure attachment, a concussion-proof housing for durability, a built-in rechargeable battery, a calibration/test cap and hose for routine checks, a USB charging cable, and a quick start guide to get you up and running quickly. Overall, the BW Flex 4 is a dependable and forward-thinking solution for gas detection. Its smart features, sensor flexibility, and rugged design make it a valuable tool for protecting workers and ensuring compliance in demanding environments.
