The Honeywell BW Ultra is a portable 5 gas detector designed specifically for sampling and monitoring confined spaces, before and after entry. Honeywell BW Ultra offers unmatched sensor technology, visibility on gas readings, comfort and connectivity. This makes it the most reliable and user friendly way to prevent a safety incident.

When you are sampling gases in a confined space, you need to constantly watch the reading on your gas detector and the Honeywell BW Ultra makes them easy to see. The detector has a 3.2″ screen and very high resolution, so you can quickly determine the level of each gas. It stands up to harsh condition. With a very high rating of IP66/68 the Honeywell BW Ultra is protected not only from dust but also from water ingress (high pressure spray or submersion up to 3.9′). So if you drop the Ultra in a vat or take it into a dust prone environmental, you can fell completely confident that is will continue to operate.

Unlike gas detectors that you wear, the Ultra is a detector that you hold as you sample the air in a confined space. That is why we designed the Ultra to fit the shape of your hand with a comfortable weight and a slimmer profile than other 5 gas detectors to prevent fatigue and increase productivity. Plus it has 1 button operation.

The Honeywell BW Ultra simultaneously detects the 4 gases you are required to monitor in confined spaces: oxygen, hydrogen sulfide, carbon monoxide and combustibles at the LEL. plus there is a 5th sensor for the gas of your choice, ranging from sulfur dioxide to chlorine to volatile organic compounds (VOCs).

Honeywell BW Ultra is compatible with the Honeywell Safety Communicator mobile app, which means that vital gas readings on the detector are no longer limited to the confined space attendant who is using it. The detector’s gas readings and location can be instantly sent via Bluetooth to Honewell’s real time monitoring software, viewable from a control room or other remote locations.

The Ultra features “Hole Watch Mode” which shows the concentration of each gas plus a graph next to every reading that shows how close the gas is to the point of alarm. You can see how fast each gas level is climbing, so you can correct small problems before they cause worker injury, evacuation or complete shutdown.

The Ultra uses the new 1-Sensor technology with small size. These sensors deliver consistently accurate readings, standing up to temperatures from -40 to 60°C. The 1-Series sensors last up to 5 years, depending on their gas exposure. With that long sensor life, backed by a 3 year warranty on the Ultra you can have confidence in your detector performance while reducing your cost of ownership.

Honeywell’s TouchConnect Technology brings Bluetooth technology to gas detection users. Simply activate your Bluetooth TouchConnect device and it will allow you to change a number of ultra devices that are within range. It will allow you to configurations or send units in to a quick Bump or Calibration mode.

*CAUTION – the LEL IR combustible gas sensor option used in the BW Ultra cannot detect certain combustible gases including hydrogen and acetylene. The application should be reviewed to ensure the Ultra can provide adequate detection.
