BW Ultra

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.

BW Ultra

Portable 5-Gas Detector

The Honeywell BW Ultra is a portable five-gas detector designed specifically for sampling and monitoring confined spaces. It is the first gas detector on the market to feature the 1-Series sensor, with fast response, reliable performance, and long life even in most extreme environments. That means high accuracy and lower costs. 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.

The BW Ultra has the one-button operation and easy experience you’ve come to expect from Honeywell detectors. And if you do need to wear the Honeywell BW Ultra as you navigate a tight space, the detector moves with you – with an internal pump and no snag points. The Honeywell BW Ultra fully complies with all safety regulations in place by detecting the five gases for added protection at work. So whether you have operations in oil and gas, pulp and paper, water treatment, shipping industry, chemical plants, or other industries, you can add the maximum level of protection for your confined space entries.
