The BW Ultra is a 5 gas detector that is designed specifically for sampling and monitoring confined spaces, before and after entry.

Five-gas detector that's been designed for confined space applications thanks to its built in pumped. Choose from configurations including standard 4 gases (LEL, O2, CO & H2S) plus PID, Cl2, CO2, NH3 or SO2.

With its unmatched sensor technology, Visibility on gas readings , comfort and connectivity, even the most extreme working conditions. Please note this product is configurable for details and pricing, please contact our sales deparment at

The BW Ultra gas detector from Honeywell is a portable monitor with a built in pump, capable of detecting up to five gases. Available sensors include VOC, LEL, CO, H2S, O2 CO2, SO2, NH3, H2, Cl2, NO2, HCN and NO.

The Ultra has been designed with confined space monitoring applications in mind. It's also suitable for inert applications and ambient monitoring, with 3 modes of operation. Hole Watch Mode is one of these operational features. This is a graphical feature that quickly determines if gas levels are reaching their alarm set points.

A new series of sensors are used in this instrument. They're of an extremely high standard and quality and will provide highly accurate readings. The Intelliflash function allows the wearer to see at a glance if the monitor is compliant. The green LED will show compliance and the reverse Intelliflash LED will flash red and show the monitor requires service.
