The Honeywell BW Ultra is a multi-gas detector designed for confined space entry, featuring single-button operation and a large 4.4 x 6.5 cm display for quick assessment of gas levels. It monitors up to five gases and includes an integrated pump with a 75 ft (23 m) sample draw range. Three operating modes—Hole Watch, Inert, and Essential—provide flexibility for different applications.

IntelliFlash and Reverse IntelliFlash indicate compliance status, while built-in Bluetooth Low Energy (BLE) enables connectivity with the free Safety Communicator App for real-time data access. The Ultra supports TouchConnect technology for easy bump testing, calibration, and set-point changes. It is IP66/68 rated, operates from -4 to 131°F, and offers up to 18 hours of battery life (14 hours with PID/IR sensors). The unit logs 30 alarm events and 10 bump events, with 45 days of data storage based on 8-hour shifts.
