Honeywell BW Flex4 Gas Detector %LEL(IR), O2, H2S, CO
Description
Keep your team safe in hazardous environments with the Honeywell BW Flex4 Gas Detector. This compact, wearable device simultaneously monitors combustible gases (except Hydrogen or Acetylene), O2, H2S, and CO with real-time readings displayed on a high-resolution screen. Intelligent 1-Series sensors provide predictive maintenance alerts to prevent failures and unexpected downtime. With two months of battery life per charge and one-button operation, workers can focus on the job while staying protected. Connect via Bluetooth to the Honeywell Safety Suite app for easy device management, incident reporting, and data analysis. Built for steel mills, wastewater treatment, paper plants, and first responder teams.
This is a "Made to Order" product that cannot be exchanged and is non-returnable. If you have any questions please call Customer Service at 800.829.9580.
The Honeywell BW Flex4 sensors in this configuration:
- %LEL(IR) — infrared (does NOT detect hydrogen or acetylene)
- Oxygen (O2)
- Hydrogen Sulfide (H2S)
- Carbon Monoxide (CO)
Caution: The infrared LEL sensor used in Honeywell BW Flex CANNOT detect hydrogen and acetylene. For applications requiring H2 or acetylene detection, see the BW Flex4 with catalytic type LEL sensor.
An LEL IR sensor draws much less power, functions in low O2 environments, and is immune to silicone poisoning. A Flex with an IR sensor should run up to 60 days without needing a charge. LEL IR is also used in the BW Clip4.
Key Features:
- Real-time gas readings at a glance
- Simultaneous monitoring of up to four gas hazards
- Reliable: 2 months of battery runtime on a 4.5-hour charge — and up to 4 months if you turn off the detector at the end of each shift
- Accurate: Low-power infrared LEL sensor is immune to silicone poisoning
- Responsive: 1 Series sensors respond to dangerous gas levels in seconds, even in harsh temperatures
- Small, lightweight and wearable; one-button operation
- IntelliFlash green light indicates the detector is in compliance; amber light indicates need for maintenance
- Compatible with IntelliDoX DX-CP instrument management and Honeywell Safety Suite via Bluetooth
- Extreme ingress protection for total confidence — stands up to dust and immersion in water
Standard Package Contents:
- Detector complete with sensors, stainless steel alligator clip, concussion-proof housing and built-in rechargeable battery
- Calibration/test cap and hose
- USB charging cable
- Quick Start Guide

Frequently Asked Questions
Why would I choose the BW Flex4 IR over the catalytic version?
The infrared LEL sensor offers dramatically longer battery life (up to 60 days per charge vs. approximately 15 hours for catalytic), works in low-oxygen environments, and is immune to silicone poisoning. It is the preferred choice for long-duration monitoring, indoor facilities with no hydrogen or acetylene hazards, or applications where frequent charging is impractical. For H2 or acetylene detection, choose the BW Flex4 %LEL(F).
Is the BW Flex4 IR returnable?
No. The BW Flex4 is made-to-order with specific sensors and cannot be exchanged or returned. Verify your LEL sensor requirements before ordering. Call PK Safety at 800.829.9580 if you have questions about which configuration is right for your application.
How long does the BW Flex4 IR battery last?
The BW Flex4 with infrared LEL sensor runs up to 60 days on a single 4.5-hour charge. Turning the monitor off at the end of each shift can extend runtime to approximately 4 months. This makes it ideal for remote or field operations where daily charging is not practical.
Does the BW Flex4 IR work with IntelliDoX?
Yes. The BW Flex4 is compatible with the BW IntelliDoX DX-CP docking station for automated bump testing, calibration, setpoint configuration, and Honeywell Safety Suite data integration. The IntelliDoX Enabler Kit DX-ENBL-NA is required.
What gases does the BW Flex4 IR detect?
The BW Flex4 IR simultaneously monitors combustible gases via infrared LEL (0-100% LEL, except H2 and acetylene), O2 (0-30% v/v), H2S (0-200 ppm), and CO (0-2000 ppm). Detection supports pre-entry atmospheric testing per OSHA 29 CFR 1910.146 and ongoing worker protection per 29 CFR 1910.1000.
Can PK Safety service or calibrate the BW Flex4?
Yes. PK Safety is a BW Technologies / Honeywell Factory Authorized Service Center. We offer factory-authorized calibration service, alarm setpoint configuration via IntelliDoX, and technical support. Call 800.829.9580 for service scheduling and fleet pricing.
