Honeywell BW Ultra 5-Gas detector
BW Technologies by Honeywell

The Honeywell BW™ Ultra is a five-gas detector from Honeywell that is designed specifically for sampling and monitoring confined spaces, before and after entry. It benefits from unmatched sensor technology, visibility on gas readings, comfort, and connectivity – even in most extreme working conditions. The Honeywell BW™ Ultra simultaneously detects the four gases you’re required to monitor in confined spaces. Plus there is a fifth sensor for the gas of your choice. This way you can add a fifth level of protection for your confined-space entries.

Extra Detection. Ultra Protection.

Unlike gas detectors that you wear, the Honeywell BW™ Ultra is a detector that you hold as you sample the air in a confined space. That’s why we designed the Honeywell BW™ Ultra to fit the shape of your hand – with a comfortable weight and a slimmer profile than other five-gas detectors – to minimize fatigue and enhance productivity.
