Gas Readings offer enhanced visibility

When you are in an area with volatile, dangerous, or explosive gases, you must constantly monitor the atmosphere. The best way to do this is with the Honeywell BW™ Ultra because the readings are clear and easy to see. High-resolution screen makes it possible to check 5 gas levels quickly and accurately.

Take it Wherever You Go

Made for enhanced durability, your Honeywell BW™ Ultra can stand some of the harshest environments. In fact, the Honeywell BW™ Ultra is rated high for moisture and dust resistance. An IP66/68 rating can withstand submersion in water as deep as 3.9 feet (1.2 meters). Your Honeywell BW™ Ultra can be dropped on the ground, into a vat of liquid, or taken into an extremely dusty area and still give you the reliable, enhanced gas protection you need for the job.

Ergonomic Design Fits Your Hand

Holding or wearing some gas detectors is awkward and uncomfortable. This is why we made the Honeywell BW™ Ultra specifically for holding comfort. It fits the hand perfectly while you take your gas readings. It is not heavy, and its slim design is easy to hold onto. This helps to prevent hand fatigue and give you better efficiency.

Works well with gloves or with bare hands

Simple 1 button operation design is so easy to use and makes gas sampling and monitoring a breeze. This is the kind of equipment you can expect from Honeywell. It is easy to wear as you go about your business. The smooth design does not snag, and internal pump runs all the time. In tight spaces, it can be your best friend.

5 Gas Sensing Capacity for Staying Safe on the Job

With your Honeywell BW™ Ultra you enjoy detection of these gases:

H2S – hydrogen sulfide
O2 – oxygen
Lower explosive limit combustible gases
CO – carbon monoxide (choose% vol, LEL or LEL%)

You can also choose a fifth gas you want to monitor or check. Do you have sulfur dioxide issues? Maybe you need to make sure deadly chlorine gas is not in the air. You can also check for volatile organic compounds, and this is important for those in the oil and gas industries, chemical and paper plants, water treatment facilities, pulp, and other industries.

Situational awareness in real-time – making monitoring gases in tight space fast and easy – helps you make quick decisions on worker safety

Safe air to breathe in confined areas is a major safety concern with many industries today. However, many problems still exist because some companies are reactive as opposed to proactive when it comes to monitoring threats.

With the Honeywell BW™ Ultra, you can prevent many accidents involving dangerous gases. While your people are inside a confined area, you can have someone just outside constantly monitoring the air for hazards. The Honeywell BW™ Ultra makes the entire process of checking for dangerous gases like H2S or CO simple and fast. This lets you correct small problems before they become major issues, giving you enhanced safety and efficiency.

Remote Monitoring (real-time) is Perfect for High-Risk Applications

The Honeywell Safety Communicator App is made to work with the Honeywell BW™ Ultra. It lets you use your gas monitoring tools in places you may not have thought possible, and more people have access too.

Bluetooth Technology gives you more options than ever. Just set up your real-time monitoring with Bluetooth, and you can monitor for possible dangerous conditions from remote locations like your control room. This provides an added layer of protection for your workers.

Hole Watch made easy thanks to Honeywell easy to understand technology

When you have people working in a confined area, your Honeywell BW™ Ultra is there to check for gas concentration changes. Just switch the Honeywell BW™ Ultra to “Hole Watch” This gives you the gas concentrations in real-time to help you maintain maximum safety, hole watch mode gives you a graph reading (ppm) of gas concentrates to help you know when any of them are close to a critical state.

Available only with Honeywell equipment, Hole Watch mode lets you check gases as they rise and fall. This gives you the chance to get all your workers to safety when needed, avoiding accidents, injuries, and downtime.

Honeywell gives you real-time gas change monitoring.

Are you sure your gas detector can do the job? Unless your detector is specifically designed for confined spaces, like the Honeywell BW™ Ultra, you may be taking some unnecessary chances with your workers’ safety.

The Finest sensor reliability and quality in the industry

Working with City Technology, we designed the 1-Series sensor. City Technology has been a worldwide producer or fine gas sensors for over forty years. The 1-Series is an upgrade from the very successful 40 XV O2 sensor in the GasAlert detector and the long-life O2 sensor, 40xLL specially made for our GasAlertMicroClip X3. You can depend on the 1-Series because our sensors have a rich history of gas detection dependability.

Do you need dependability with no nuisance trippig – in the harshest of environments?

Do not let its size fool you. The 1-Series sensor gives you some of the most accurate gas readings even in temperatures as cold as -40 F and as warm as 140 F. Now add other factors like pressure humidity, wind, and precipitation.It does not matter how extreme the conditions, your Honeywell BW™ Ultra is up to the task for dangerous gas detection.

No senor changes for five years

If you invest in some gas detecting equipment you may need to change sensors often. In fact, some may not last you a year and you end up spending a lot of money.

Plus you have to take the units out of service to replace sensors. The Honeywell BW™ Ultra can give you 60 months of continuous sensor service (depending on usage)

In addition, we provide a 36 month warranty on our Honeywell BW™ Ultra models for cost-effective gas detection with few maintenance issues.

Would you like to increase your operating efficiency while reducing your downtime and equipment costs? Consider the Honeywell BW™ Ultra.

Do you spend too much time with bump tests? Our Honeywell BW™ Ultra is designed to facilitate this task.

Bumping is easy, and you do not even need docking stations.

Your TouchConnect™ device can locate your detectors for you and put them into bump mode.

Simple configuration for one unit or an entire fleet

Setting gas concentration alarms is sometimes time-consuming but when you have the Honeywell BW™ Ultra and TouchConnect™ Technology, alarm setting is simplified.

You only need to turn to your TouchConnect™ device to automatically setup your configuration settings.

This is very convenient for companies with many gas detectors (in branches all over the planet) to track and maintain) and you don’t need docking stations or special software programs.

Just contact each branch with your TouchConnect™. Your Bluetooth feature does the work for you.

Detecting Five Hazardous Gases

Do you face multiple gas hazards in your line of work? The Honeywell BW™ Ultra can detect more than just CO and O2. It can also tell if there are unsafe levels of LEL and H2S. In addition, you can also select a fifth setting for your specific applications. Here are some examples:

  • SO2 – for those in the oil, gas, paper and pulp industries
  • CL2 – wastewater treatment, water treatment, pools, and paper industries
  • NH3 – pool systems, chemical, agricultural, refrigeration, and paper industries.
  • CO2 – beer and wine industries
  • HCN – food and perishables
  • NO2 – construction
  • VOCs – companies using paints or solvents


Solving Inert Environment Problems

When you use your inert mode on the Honeywell BW™ Ultra, you can check your environment for low O2 levels. Your gas detector automatically adjusts the settings for O2 level alarms, and it can adjust for normal atmospheres or inert atmospheres.

Do you need more than just gas detection for confined spaces?

Your Honeywell BW™ Ultra is specifically made to perform well in the most tightest and confined spaces. However, you can also use it for monitoring and sampling other parts of your work area. For example, are there possible chlorine hazards or do some of your workers have to be around volatile organic compounds for cleanup tasks? You can use your Honeywell BW™ Ultra for these jobs. Simply take out the sample hose, and you have a full-time gas monitor, saving you a lot on operating expenses.

Your Honeywell BW™ Ultra protects you, your crew, and your entire operation
