The BW Ultra Gas Detector is now obsolete as of the 30th June 2026. The replacement would be the Flex 5, a modular system that can detect up to 6 gases and includes a built-in pump.
The BW Ultra five-gas detector is designed for use in confined spaces and has an internal pump. Its lightweight, slim design makes it more portable than traditional five-gas detectors and fits comfortably in your hand. Operated with a single button, it displays real-time gas readings on a large, high-resolution, scratch-resistant screen.
All models detect the four core gases: Flammable, Carbon Monoxide, Hydrogen Sulphide, and Oxygen, with the option to add a fifth sensor.
Remote monitoring is possible using Bluetooth, which connects to Honeywell’s Safety Communicator App, providing an additional layer of protection.
Features
- Repeatable performance without nuisance alarms – even in most extreme conditions.
- Hole watch mode provides a graphical indication of how close the gas concentration is to the alarm threshold, enabling a preemptive response.
- Expected sensor lifetime: up to 5 years.
- IntelliFlash and reverse IntelliFlash for visual compliance.
- Compatible with the IntelliDoX system for bump testing and calibration.
- Honeywell TouchConnect Technology for quick instrument management.
- Battery life is 18 hours (14 hours with PID or IR sensor).
- Robust Honeycomb housing.
- Warranty: Instrument: 3 years. Sensors: 3 years (2 years NH3, 1 year PID and Cl2). Battery: 2 years.
- Ingress Protection IP66/68.
- ATEX, IECEx & UL certification.
- Size 14.8 x 8.5 x 4.0 cm, weight 411 g.
